From the southern end of G1 on Fremont Peak as San Juan Canyon Road, G1 begins a steep, sharp-curved winding descent from around 3,000 feet for the first 2 miles, north to northeast. G1 then curves to the west for about 2 miles before turning north. At the intersection of Mission Vineyard Road, G1 becomes The Alameda, which then heads north for approximately 1/4 mile before reaching the northern terminus at State Route 156. Beyond the northern terminus, The Alameda continues into downtown San Juan Bautista for 0.2 miles until the intersection of First Street.
County Route G2 (CR G2), more commonly known as Lawrence Expressway and Quito Road, is a busy 9.7-mile (15.6km) long north–south link through Silicon Valley in Northern California. The majority of G2 is part of the Santa Clara County expressway system.
G2 runs from the Quito Road overcrossing of SR 85 in Saratoga, north along Quito Road. G2 is not signed along this section and is not commonly recognized as existing along this 2 lane road by either locals or mapmakers. The Quito Road portion is also maintained by the City of Saratoga rather than Santa Clara County.[2]
As the road leaves Saratoga and enters San Jose, it widens to a 6 lane county-maintained expressway with a concrete island divider; at this point it becomes Lawrence Expressway. The Lawrence Expressway section from just south of Saratoga Avenue is more readily recognized as G2. Local residents almost exclusively refer to G2 as Lawrence Expressway. The road continues north, with access usually restricted to major intersections which are controlled via traffic lights.
Lawrence Expressway continues northeasterly and junctions with I-280 and Stevens Creek Boulevard over a complex shared separated grade crossing. Lawrence Expressway proceeds under I-280 before immediately rising over Stevens Creek Boulevard. San Tomas Expressway and Campbell Avenue also share ramps for access to I-280 with the exception of the onramp to Southbound I-280 which is accessed directly from Lawrence Expressway, a frequent cause of confusion for drivers on Stevens Creek Boulevard wishing to access I-280 due to unclear signage.[citation needed] Lawrence Expressway continues north into Santa Clara and widens to 8 lanes with an HOV lane occupying the far right lane.
Lawrence (looking south, center) at Central Expressway
Lawrence Expressway also has another separated grade interchange with El Camino Real (SR 82). Lawrence Expressway then enters Sunnyvale. At this point the expressway passes over Caltrain's Lawrence Station. Lawrence Expressway also passes under Central Expressway (G6) on a separated grade interchange and over US 101 on a separated grade interchange. The US 101 interchange was upgraded in the early 2000s to include traffic light control on G2.
G2 reaches its northern terminus at the end of Lawrence Expressway at the SR 237 Freeway. The physical road continues north as Caribbean Drive, which then curves back south through Sunnyvale and Cupertino, paralleling Lawrence Expressway under several different street names until the roads intersect again at Highway 9 and Quito. This effectively makes the road one continuous counterclockwise loop through the Santa Clara Valley, where one driver could start on Quito road and end up exactly where they started without ever changing lanes.
History
The designation G2 existed to the 1950s. The route replaced what was originally called Lawrence Station Road (after the Southern PacificLawrence station), from Mountain View–Alviso Road in the north to Stevens Creek Blvd. on the south, roughly paralleling Saratoga Creek. Lawrence Station was itself named for Alfred Chester Lawrence.[3] Crossing Stevens Creek, the route was originally called Doyle Road, a small two lane road up to the point the current Doyle Road exits to the east. The section between Doyle and Saratoga Avenue at Quito Road was originally orchards.[4]
G2 was first signed as a Santa Clara County Route in 1962 as construction was completing on sections of the upgrade to an expressway. County Route G2 was originally planned to link up with SR 85 when it was built. At the time of G2's inception SR 85 was in the early planning stages and an interchange had been envisioned at Quito Road. However opposition to the freeway was intense in Saratoga and the planned interchange between SR 85 and G2 along with an interchange further north at Prospect Road were abandoned in favor of the existing Saratoga Avenue interchange. G2 is unsigned from SR 85 to Saratoga Avenue along Quito Road. North of Saratoga Avenue, Lawrence Expressway is currently signed as G2.[5]
In the 1990s Lawrence Expressway was widened north of I-280 to 8 lanes to accommodate an HOV carpool lane.
As of 2019, Santa Clara County is planning a major grade separation project at Homestead Road. This will be one of the largest expressway improvement projects in many years.[6]
Animation of USGS maps of 1953, 1961, 1969, 1974, and 2015, showing the conversion of Oregon Avenue to Oregon Expressway, and its interchange with Alma Street and connection to Page Mill Road. In 1953, Oregon Avenue had a T intersection with Alma Street, while Page Mill Road and California Avenue had level crossings across the Southern Pacific railroad tracks. By 1961, the left-jog underpass connection between Page Mill Road and Oregon Avenue had been made, but Oregon was still a narrow residential street, which connected to US-101 so it became a very busy route to Stanford and the Stanford Industrial Park. By 1969, the Oregon Expressway had replaced about 90 homes on the south side of Oregon Avenue. By 1974, more ramps were added to the Alma Street interchange. At some point, by 2015, the railroad tracks behind the Sutter Packing Company cannery / Maximart / Fry's building were gone (where the 2015 map says "Mayfield"); this was the track that connected the Peninsular Railway route that ran along what became Foothill Expressway.
County Route G3 (CR G3), more commonly known as Page Mill Road and Oregon Expressway, is a short 4.5-mile (7.2km) northeast–southwest arterial route that spans the lower peninsula region of the San Francisco Bay Area from I-280 to US 101. G3 runs through Palo Alto and unincorporated Stanford University lands. It is part of the Santa Clara County expressway system.
Route description
Page Mill Road heading downhill toward Hanover Street and El Camino RealOregon Expressway where it goes under Park Blvd., the Caltrain tracks, and Alma Street (which is also the start of G6)
CR G3 begins in the west at its interchange with I-280, at the Los Altos Hills–Stanford border. It proceeds northeast as a four lane expressway over the rolling hills of Stanford University until it reaches Foothill Expressway (G5), at which it has an at-grade intersection. East of Foothill Expressway, G3 descends down into the more urban areas of the lower peninsula, going through the industrialized area of the Stanford Research Park located in Palo Alto. The road along this section has a reduced speed limit and several turnoffs along its length until it reaches El Camino Real (SR 82).
After SR 82, G3 branches from Page Mill Road (which becomes a narrow access road to the California Avenue Station), and curves under the Caltrain tracks, continuing as Oregon Expressway for the remainder of its northeastward journey. Oregon Expressway functions more comparably to a County-maintained Arterial Road for Palo Alto, with frequent signaled intersections and a posted speed limit of 35 MPH. G3 reaches its eastern terminus at its junction with US 101, where it shares an interchange with Embarcadero Road.
Page Mill Road (no longer designated G3) continues southwest of I-280 for 6 miles (9.7km), a twisting two-lane road that climbs to Skyline Boulevard (SR 35) at the crest of the Santa Cruz Mountains. It passes the entrance to Palo Alto's Foothills Park, and the Monte Bello and Los Trancos Open Space Preserves. Under the name West Alpine Road, the road descends west of Skyline Boulevard to a turn-off that leads to Portola Redwoods State Park, where the original Page sawmill was located. Other than a commemorative sign, no artifacts remain at the mill site, which is accessible only by Slate Creek Trail from either Portola Redwoods state park or from Skyline Boulevard (SR 35).
History
This route was designated in 1962. G3 is currently signed its entire length. Page Mill Road was originally known as Mayfield–Pescadero Road,[7] but only the urbanized portion of Page Mill Road is part of G3.
The widening of Oregon Avenue from a congested narrow residential street to a median-divided 4-lane Oregon Expressway was narrowly approved by Palo Alto voters in a June 5, 1962, election; about 90 homes on the south side of Oregon Avenue were moved or destroyed to make room for it.[8] The original Oregon Ave still exists on the north side of the roadway, though is mostly separated from G3 with trees and shrubbery.
Due to the steep grade and high water table around the area of the Caltrain underpass, the underpass is notorious for flooding during heavy rains, which often overwhelmed the county pumps which were installed due to the existence of a Superfund site 1/4 mile upstream on Page Mill road.[9] When the underpass is closed due to flooding, through traffic must detour onto Alma Street (Route G6) and cross the train tracks at either Churchill Ave to the North, or Charleston Rd to the south.
When Interstate 280 was completed through the area in 1969, the old narrow Page Mill road, which passed by the Frenchman's Tower, was bypassed over the hills to the south and expanded to 5 lanes from 2. The old road was renamed "Old Page Mill Road", the center line was removed, and car access was limited to eastbound and local traffic only. The road is still traversable today and is a popular route for bicyclists.
In 2014, the county began a rehabilitation project on Oregon Expressway, which entailed rebuilding and landscaping of the center median, installation of new traffic lights and mast arms, and repaving of the travel lanes. The intersection of Ross and Oregon, previously an uncontrolled intersection, had new traffic signals and sensors installed and Ross was converted into a Bike Boulevard.
County Route G4 (CR G4), more commonly referred to as San Tomas Expressway and Montague Expressway is a busy 14.5-mile (23.34km) long link across Silicon Valley. G4 is part of the Santa Clara County expressway system.
CR G4 begins in the south at its interchange with SR 17 and Camden Avenue as San Tomas Expressway in the city of Campbell. The road is three lanes wide in each direction, with an HOV carpool lane occupying the right lane, from SR 17 north to Homestead Road, where it expands to four lanes in each direction with an HOV lane until San Tomas "ends" at US 101. The majority of intersections along San Tomas are at grade, controlled by traffic lights. The only grade-separated intersections along San Tomas are at SR 17, US 101, Winchester (necessary due to a Union Pacific branchline), and the junction with Central Expressway (G6). G4 intersects at grade with El Camino Real in Santa Clara. Further north in Santa Clara, G4 crosses US 101 and becomes Montague Expressway.
Montague Expressway is signed as an east–west route, however it is not signed as G4 along its entire length. Montague continues east as an 8 lane road until it crosses Interstate 880 on the San Jose/Milpitas city line, where it loses a lane to become a 6 lane road. G4 reaches its eastern terminus at Interstate 680 but the physical road continues as Landess Ave further east until it ends at its intersection with Piedmont Road.

G4 was designated and signed in 1962 along the San Tomas portions. Montague was designated later around 1978. Whether this has anything to do with Montague and not being physically signed as G4 is uncertain. Emergency Call boxes along Montague however are labeled as being on G4 leaving no doubt that Montague is part of G4.
Original plans called for G4 to include Hillsdale Avenue and Camden Avenue, between its present-day southern terminus and the southern terminus of Capitol Expressway (G21).[citation needed] These plans were never brought to fruition.

County Route G5 (CR G5), more often referred to as Foothill Expressway, is a 4-lane, 7.24-mile (11.65km) long, northwest–southeast route in Santa Clara County, California, United States. It connects Palo Alto to the Silicon Valley proper closely paralleling Interstate 280 through the lower Santa Cruz Mountains foothills. CR G5 is part of the Santa Clara County expressway system. The speed limit for Foothill Expressway is 45 MPH.
Route description
CR G5 begins at its southeastern end at I-280 in Cupertino, California. It proceeds northwest directly east of I-280 making it a viable alternative route for short trips between Cupertino and Palo Alto. The road is a four-lane expressway along its entire route. Access is generally limited to major intersections that are governed by traffic lights except for an interchange at Fremont Avenue, which the interchange also provides access to Miramonte Avenue and Loyola Drive. CR G5 travels through several affluent neighborhoods in Los Altos before reaching its northern terminus at the intersection with Page Mill Road (CR G3). The physical road continues north as Junipero Serra Boulevard and passes the back entrances to Stanford University. In the south, the road continues past Foothill Boulevard onto Stevens Canyon Road, a winding mountain road that passes by a rock quarry and several open space preserves.
History
G5 was designated in 1962 and is currently signed its entire length. The route was built upon the right-of-way for the Los Altos branch of the Peninsular Railway.[10] The buildings along the route at Loyola Corners in Los Altos are historical railroad station buildings.
In 1970, one of the first scientifically designed noise barriers in the nation was conceived for Foothill Expressway in a study overseen by the Santa Clara County Public Works Department using Sunnyvale consultant ESL Inc.
In 2021, Route G5 saw one of its only major expansions from since it was first built; the section of Foothill between San Antonio Road and El Monte Avenue was widened from 4 lanes to 6, complete with removal of the dedicated right-turn ramps and installation of new traffic signals. This section of CR G5 often sees heavy commuter traffic, particularly from motorists accessing I-280 from San Antonio Road via El Monte.

County Route G6 (CR G6) is a signed 12.3-mile (19.8km) long, east–west route in the western portion of Silicon Valley in Santa Clara County, California, United States. It comprises mainly of Central Expressway, as well as portions of Alma Street in Palo Alto and De La Cruz Boulevard in San Jose. While paralleling US 101, El Camino Real (SR 82) and I-280, all of which are signed north–south, Central Expressway is signed east–west. This is due to the fact that all of these routes move in an east–west direction in this area, but these other routes continue longer than Central Expressway and are mostly north–south overall. This route is part of the Santa Clara County expressway system.
Route description
CR G6 actually begins in the west at Oregon Expressway (CR G3) as Alma Street in Palo Alto. In Palo Alto, CR G6 remains a major surface street with four lanes of traffic and a center turning lane to service the many driveways and turnoffs available. At the Palo Alto –Mountain View border at San Antonio Road, CR G6's character changes, removing the driveways and frequent intersections and adding a center divider, and is known as Central Expressway. Central continues east as a 4-6 lane road through the city of Mountain View. There are signalized intersections at major thoroughfares, and there is a grade crossing for the VTA Light Rail. This section's intersections are primarily at-grade with cross streets controlled by traffic lights, although there are some overpasses, such as for San Antonio Road, Shoreline Boulevard, SR 85, Whisman Road, SR 237, and Middlefield Road.
Up to this point, the roadway has paralleled the Caltrain rail line all the way from the Palo Alto station, which limits the intersections on the south side of the road. The roadway branches off from the railway at Bernardo Avenue.
After crossing under SR 85, Central Expressway takes on a very freeway-like appearance (which is not typical for most county roads) for several miles through Sunnyvale. Through this section, Central Expressway has a wide center divider with guardrails, and access is limited to a sequence of several separated grade interchanges at main cross streets with no turnoffs or driveways. The final in this sequence is at Lawrence Expressway (CR G2). East of CR G2, Central resumes at grade intersections along with sporadic HOV lanes at the approaches to intersections. Central has one final separated grade interchange with San Tomas Expressway (CR G4).
After CR G4, Central Expressway continues east for about a mile as a 6-lane expressway until it abruptly ends at De La Cruz Boulevrad, where all lanes must turn left or right. CR G6 continues for a few hundred feet north on De La Cruz until it reaches its terminus at US 101, just outside the north end of the runways for San Jose International Airport. The physical road continues as Trimble Road towards CR G4, while at its western terminus in Palo Alto, Alma Street continues northwest through downtown Palo Alto until Alma ends at El Camino Real near the border of Palo Alto and Menlo Park.
The posted speed limit on CR G6 is 50 MPH (80 km/h). In Mountain View, the posted limit drops to 45 MPH.
History
Central Expressway was first designated in 1962. Central Expressway was a vital route through the western Silicon Valley in the days before US 101 had been widened and I-280 had been built as an alternate route. Central Expressway still acts as an alternate route to US 101 through the west valley, however usage has declined as both freeways are now much larger and more direct routes.
In 1982, the prohibition against bicyclists using Central Expressway's shoulders was lifted. All pedestrian prohibitions were repealed by 2003.
In 2007, construction was completed near the eastern terminus widening Central Expressway to accommodate an HOV lane and a reconfiguration of the intersection with Lafayette Street.
In 2016, VTA expanded the Central Expressway grade crossing from 1 track to 2 tracks, necessitating some closures between Whisman and Mary for construction. CR G6 was also closed to vehicular traffic in the same stretch on the day of Super Bowl 50 so that Light Rail traffic would have priority to Levi's Stadium.[11]
In 2020, Mountain View closed Castro Street to vehicular traffic to support outdoor dining in the wake of the COVID-19 pandemic. The road is still closed to this day, and the turn pockets onto Castro Street from Central remain coned off while the city and county determine more permanent plans for this intersection.
In early 2023, the eastern terminus of CR G6 was modified to match the new configuration of the De La Cruz Boulevard / US 101 interchange. The right slip ramps to/from De La Cruz on Central were permanently closed to traffic and replaced with standard right turn lanes.
Central Expressway is currently signed as CR G6 sporadically along its entire length.
The route serves as a bypass for travelers who are traveling from westbound State Route 152 to southbound U.S. Route 101. County Route G7 bypasses SR 152 at the US 101 interchange, where SR 152 is signed as 10th Street. This bypass avoids considerable amounts of traffic congestion that is the result of large retail shopping centers on both sides of 10th Street.
CR G7 also serves Frazier Lake Airpark via Frazer Lake Road, as well as the Christopher Ranch garlic facility.
Almaden Expressway at its interchange with Route 85
County Route G8 (CR G8) is an important north–south arterial road from the South Valley area of Santa Clara County, California, United States, to near Downtown San Jose. It runs for 29.4 miles (47.3km) over both rural roads, expressway and urban streets, but it is most commonly known by residents for its expressway portion, Almaden Expressway. The route is also known as Watsonville Road, Uvas Road, McKean Road, and small portions of Harry Road, Almaden Road, and Alma Avenue. CR G8 is also part of the Santa Clara County expressway system.
Route description
CR G8 begins in the south at its junction with State Route 152 in Gilroy. It proceeds north along Watsonville Road as a two-lane country road until it reaches the intersection of Watsonville Road and Uvas Road. CR G8 turns left and proceeds north along Uvas Road which is a winding two-lane mountain road that passes by Uvas, Chesbro and Calero reservoirs and their surrounding parks. In Calero Reservoir County Park, Uvas Road transitions to McKean Road and proceeds into the Almaden Valley area of San Jose. At the north end of McKean Road, CR G8 turns briefly right on Harry Road for a short distance and then left on to the south end of Almaden Expressway.
As Almaden Expressway, CR G8 begins as a 2-lane undivided road for 1/2 mile before expanding to 4-lane divided expressway approaching the intersection of Almaden Road. Almaden Expressway eventually expands to a 6-8 lane expressway with the majority of access limited to major intersections controlled by traffic signals. The major exception to this is near State Route 85 and Blossom Hill Road (CR G10) where there are several major shopping centers.
CR G8 intersects CR G10 at Blossom Hill Road and SR 85 a quarter mile north. This interchange is one of the busiest in Silicon Valley due to several shopping centers and a Costco warehouse store all sharing driveways with this interchange. CR G8 continues north resuming its expressway design. It shares a separated grade interchange with the terminus of Capitol Expressway Auto Mall and again with Curtner Avenue. Other intersections along this part of the route are at grade. Almaden Expressway crosses State Route 87 with which it shares a northbound only interchange.
CR G8 continues past the north end of Almaden Expressway on to Almaden Road as a 4-lane city street. At the intersection Almaden Road and Alma Avenue, CR G8 turns east along Alma Avenue and proceeds for about a quarter mile to its eastern terminus at First Street (former SR 82).
History
CR G8 was originally designated in 1962 along Almaden Expressway which had begun construction in 1959. Almaden Expressway was not completed to its southern terminus until 1984. Before that time the section between McKean Road and the southern end of the expressway (which was further north at the time) took a zig zag path from McKean Road to Harry Road to Almaden Road (S) to Barnes Lane, to the then southern end of Almaden Expressway.
CR G8 is signed sporadically along its entire length.
County Route G9 (CR G9) is a road in Santa Clara County, California, United States. The route runs along Leavesley Road from State Route 152's northern interchange with US 101 in Gilroy and then curves southward onto Ferguson Road. The route's eastern terminus is at SR 152 (Pacheco Pass Highway) east of Gilroy.
County Route G9 serves shoppers traveling to the Gilroy Premium Outlets, which features more than 145 stores and is the largest collection of outlet stores in Northern California.[12]
County Route G9 serves several agricultural facilities along its route. It also serves travelers as a bypass around the city of Gilroy, who wish to avoid the congestion at 10th Street and U.S. Route 101.
County Route G10 (CR G10), known as Los Gatos-Saratoga Road, Los Gatos Boulevard, and more commonly known along the majority of its route as Blossom Hill Road for the majority of its length, is an important east–west arterial roadway through the Almaden Valley area of Santa Clara County, California, United States in the Silicon Valley. The route runs for 10.34 miles (16.64km) and is a series of city streets for its entire length.
Route description
County Route G10 begins at its western end at the junction of SR 17 and Los Gatos-Saratoga Road (formerly Saratoga Avenue) in Los Gatos. It travels east on Los Gatos-Saratoga Road to the end of that road then turns northeast along Los Gatos Boulevard. CR G10 proceeds for about 3⁄4 mile (1.2km) to Blossom Hill Road where it turns east. Along this stretch, CR G10 is a narrow road that proceeds over Blossom Hill, the hill that the road takes its name from. At the base of Blossom Hill, CR G10 enters San Jose and the Almaden Valley neighborhood.
CR G10 proceeds as a busy 4-6 lane artery through this area, intersecting Almaden Expressway and further east, through the Blossom Valley neighborhood of San Jose, to SR 85. Prior to the completion of the segments of SR 85 between 1991 and 1994, which CR G10 roughly parallels, Blossom Hill Road was the major accessway to this area of San Jose from the west.
CR G10 reaches its eastern terminus at former prior-to-2013 SR 82, a few hundred feet (~100 meters) shy of US 101. Blossom Hill Road continues to US 101 and then over the freeway becoming Silver Creek Valley Road, before continuing as Nieman Boulevard and terminating at the junction with Capitol Expressway.
History
G10 was designated in 1964 as a county road. As of 2005, however, the road is no longer maintained by the county and is city street along its entire length. G10 is also only sporadically signed along its route and has been largely abandoned by the county after the completion of SR 85.
County Route G11 begins as San Juan Road at the intersection of Porter Drive (County Route G12) in Pajaro. It leaves Pajaro and continues east for a 3/4 mile before gradually turning southeast towards Aromas. The road enters a brief, but steep hill for a 3/4 mile with a passing lane, then returns as a two-lane road turning south and then southeast. Nearing the eastern terminus at US 101, CR G11 curves to the east and then sharply turns southeast. CR G11 crosses into San Benito County approximately one hundred feet (60 meters) before reaching its terminus at US 101.
It provides an alternative route from Gilroy and Hollister towards Santa Cruz, bypassing the twistier, hillier routes 152 and 129, which, like Highway 17, can be daunting to novice drivers.
County Route G12 (CR G12) is a county road in Monterey and Santa Cruz counties in the U.S. state of California. The route, running almost 11 miles (18km), begins at US 101 near Prunedale and follows San Miguel Canyon Road4 miles (6km)north-northwestward to Hall Road, onto which the route turns westward for 3 miles (5km) passing through the community of Las Lomas. This portion arrives at Elkhorn Road, where G12 turns northward for 1 mile (2km) before joining Salinas Road first to enter Pajaro, where the route becomes Porter Drive, and then crosses into Santa Cruz County to enter Watsonville, where the route joins Main Street and terminates at State Route 129.
North end of Elkhorn Road; south end of Salinas Road on CR G12; access from CR G12 north to Salinas Road south and from Salinas Road north to CR G12 south is via Werner Road

County Route G13 (CR G13) is a county road in Monterey and San Benito counties in the U.S. state of California. The route runs almost 16 miles (26km) between King City in Monterey County and State Route 25 in San Benito County. It is known as Broadway Circle, Broadway Street, a portion of First Street, Lyons Street, and Bitterwater Road.
Route description
CR G13 begins in King City at the interchange with U.S. Route 101 in King City as a city street. It turns east through downtown King City for 1 mile (2km) before turning northwest on First Street, which then becomes Lyons Street and turning northeast to become Bitterwater Road, passing Mesa Del Rey Airport and leaving the city limits. G13 then enters a hilly area before crossing into San Benito County for an additional 6 miles (10km) and terminating at the junction of State Route 25 at Bitterwater.
CR G14 begins at the intersection of US 101 and State Route 46 in Paso Robles. It then heads west for less than one mile (~1.5km) before leaving the city limits as Nacimiento Lake Drive and turning mainly northwest for 15 miles (24km). G14 then crosses the Nacimiento Dam for 1/4 mile before reaching a steep hill with a brief winding curve. G14 then turns west onto Interlake Road while Nacimiento Lake Drive continues as CR G19. As Interlake Road, G14 heads west with a brief curve to the north for a few miles and passing Lake San Antonio before turning mainly northwest and eventually north towards the town of Lockwood. Just a few hundred feet (~100 meters) south of Lockwood, G14 reaches the intersection of the western terminus of CR G18 and heads west along Jolon Road. As G14 reaches the small town of Jolon, a side road provides an entrance to the Fort Hunter Liggett military facility while G14 curves to the north. G14 continues north through the southern end of the Santa Lucia range for several miles to reach the southern Salinas Valley. G14 terminates at US 101 west of King City.
The route begins at US 101 southeast of King City and follows First Street through the city, where it intersects County Route G13 and exits the city as Metz Road. G15 follows this road 17 miles (27km)northwestward, bypassing Greenfield for the unincorporated community of Metz and terminating at State Route 146 near Soledad.
County Route G17 (CR G17) is a county road in Monterey County, California, United States. The route was constructed in 1955, and is part of the De Anza National Historic trail. It wasn't one of the original Signed County Routes but was added in 1965.[14] CR G17 runs from Elm Avenue (CR G16) west of Greenfield to State Route 1 in Marina.[1] The route is known as Arroyo Seco Road, Fort Romie Road, River Road, Reservation Road and the River Road Wine Trail.
Route description
County Route G17 begins as a three-way intersection with CR G16 near Millers Ranch as Arroyo Seco Road. It then briefly heads northeast before turning north for several miles closely paralleling the eastern end of the Arroyo Seco until at the intersection at Fort Romie Road south of Fort Romie. G17 then proceeds northwest on Fort Romie Road as Arroyo Seco Road continues east to its terminus at US 101. Just after passing the Mission Soledad historic site, G17 turns southwest for 1000 feet before reverting northwest. G17 continues for another 2 miles until the intersection with Foothill Road, becoming River Road. As River Road, G17 continues northwest for several more miles along the Salinas River until the intersection with Gonzales River Road near Gonzales, which G17 turns southwest for 1/4 mile before reverting northwest. As the road nears Chualar, G17 has another intersection with Chualar River Road and heads northwest, closely following the Salinas River. Shortly before the interchange with State Route 68, G17 becomes a 4-lane undivided road for about 1/2 mile before reverting to a 2-lane road and becoming Reservation Road.
As Reservation Road, G17 continues northwest along the Salinas River with occasional sharp curves until reaching a brief steep hill south of Marina and becoming a 4-lane divided road. G17 remains a 4-lane divided road for most of the length through Marina except between Del Monte Boulevard and Beach Road. At Del Monte Boulevard, G17 truncates back to a 2-lane city street, progressively turning north, with traffic circles until the intersection of Beach Road. G17 which then turns northwest for 600 feet, resuming a 4-lane road until the northern terminus at State Route 1.

County Route G18 (CR G18), known entirely as Jolon Road, is a county road in Monterey County, California, United States. Jolon Road itself runs between U.S. Route 101 on both ends. Although Jolon Road runs on both ends of 101, the western terminus of CR G18 is near Lockwood with the intersection of CR G14 and runs for approximately 16.4 miles.
Route description
County Route G18 begins at the intersection of CR G14 (Interlake Road) and proceeds east for several miles as a continuation of Jolon Road. There is a junction with CR G19 (Nacimiento Lake Drive) just a few hundred feet shy of its eastern terminus with US 101.
County Route G19 begins at its southern terminus at Interlake Road, which is a continuation of the CR G14 portion of Nacimiento Lake Drive. G19 heads northeast for approximately 1.25 miles (2km) until the intersection with Vista Road. Vista Road provides access to Lake San Antonio, while G19 continues east, progressively turning north and crossing the San Antonio River before a sharp curve to the east.

History
Capitol Expressway was designated in 1978 from Almaden Expressway to US 101, including what is now Capitol Expressway Auto Mall. Construction on the eastern portion from US 101 to I-680 was not completed until 1997.
In the late 1990s the portion of the expressway from Almaden Expressway to SR 87 was transferred from Santa Clara County to the city of San Jose. San Jose then converted it into an auto row and renamed it Capitol Expressway Auto Mall.
Capitol Expressway is signed as G21 along its length.
