The Arroyo Seco Parkway, also known as the Pasadena Freeway, is one of the oldest freeways in the United States. It connects Los Angeles with Pasadena alongside the Arroyo Seco seasonal river. Mostly opened in 1940, it represents the transitional phase between early parkways and later freeways. It conformed to modern standards when it was built, but is now regarded as a narrow, outdated roadway. A 1953 extension brought the south end to the Four Level Interchange in downtown Los Angeles and a connection with the rest of the freeway system.
Route 110, consisting of State Route 110 (SR 110) and Interstate 110 (I-110), is a state and auxiliary Interstate Highway in the Los Angeles metropolitan area of the US state of California. The entire route connects San Pedro and the Port of Los Angeles with Downtown Los Angeles and Pasadena. The southern segment from San Pedro to I-10 in downtown Los Angeles is signed as I-110, while the northern segment to Pasadena is signed as SR 110. The entire length of I-110, as well as SR 110 south of the Four Level Interchange with US Route 101 (US 101), is the Harbor Freeway, and SR 110 north from US 101 to Pasadena is the historic Arroyo Seco Parkway, the first freeway in the western United States.
Route 710, consisting of the non-contiguous segments of State Route 710 (SR 710) and Interstate 710 (I-710), is a major north–south state highway and auxiliary Interstate Highway in the Los Angeles metropolitan area of the U.S. state of California. Also called the Los Angeles River Freeway prior to November 18, 1954, the highway was initially planned to connect Long Beach and Pasadena, but a gap in the route exists from Alhambra to Pasadena through South Pasadena due to community opposition to its construction.
The Hollywood Freeway is one of the principal freeways of Los Angeles, California and one of the busiest in the United States. It is the principal route through the Cahuenga Pass, the primary shortcut between the Los Angeles Basin and the San Fernando Valley. It is considered one of the most important freeways in the history of Los Angeles and instrumental in the development of the San Fernando Valley. It is the second oldest freeway in Los Angeles. From its southern end at the Four Level Interchange to its intersection with the Ventura Freeway in the southeastern San Fernando Valley, it is signed as part of U.S. Route 101. It is then signed as State Route 170 north to its terminus at the Golden State Freeway.
Interstate 105 (I-105) is an east–west auxiliary Interstate Highway in the Greater Los Angeles urban area of Southern California. It runs from State Route 1 (SR 1) near El Segundo and Los Angeles International Airport (LAX) to Studebaker Road in the City of Norwalk. It is commonly known as the Century Freeway after Century Boulevard which it parallels, and also officially known as the Glenn Anderson Freeway after the late congressman Glenn M. Anderson who advocated for its construction.
State Route 60 (SR 60) is an east–west state highway in the U.S. state of California. It serves the cities and communities on the eastern side of the Los Angeles metropolitan area and runs along the south side of the San Gabriel Valley. It functions as a bypass route of Interstate 10 (I-10) through the area between the East Los Angeles Interchange in Los Angeles and Beaumont.

A continuation of the municipal Don Valley Parkway (DVP) north of Highway 401, it connects Toronto with East Gwillimbury. The 50.1-kilometre (31.1 mi) controlled-access freeway also connects with Highway 407 in Markham, which formed the northeastern ring road of the Greater Toronto Area until the opening of Highway 412 in 2016. Highway 404 provides access to the eastern edge of Richmond Hill, Aurora and Newmarket and the western edge of Whitchurch-Stouffville, in addition to the southern edge of Keswick.
The Hampton Roads Beltway is a loop of Interstate 64 and Interstate 664, which links the communities of the Virginia Peninsula and South Hampton Roads which surround the body of water known as Hampton Roads and comprise much of the region of the same name in the southeastern portion of Virginia in the United States. It crosses the harbor of Hampton Roads at two locations on large four-laned bridge-tunnel facilities: the eastern half carries Interstate 64 and uses the Hampton Roads Bridge-Tunnel and the western half carries Interstate 664 and uses the Monitor-Merrimac Memorial Bridge-Tunnel. The beltway has the clockwise direction signed as the Inner Loop, and the counter-clockwise direction signed as the Outer Loop. The entire beltway, including the bridge-tunnels, is owned and operated by the Virginia Department of Transportation.
King's Highway 403, or simply Highway 403, is a 400-series highway in the Canadian province of Ontario that travels between Woodstock and Mississauga, branching off from and reuniting with Highway 401 at both ends and travelling south of it through Hamilton and Mississauga. It is concurrent with the Queen Elizabeth Way (QEW) for 22 km (14 mi) from Burlington to Oakville. The Highway 403 designation was first applied in 1963 to a short stub of freeway branching off the QEW at Burlington, and the entire route was completed on August 15, 1997, when the section from Brantford to the then-still independent Town of Ancaster was opened to traffic. The section of Highway 403 between Woodstock and Burlington was formally dedicated as the Alexander Graham Bell Parkway on April 27, 2016, in honour of Alexander Graham Bell.
A vast network of interconnected freeways in the megaregion of Southern California serves a population of over 23 million people. The Master Plan of Metropolitan Los Angeles Freeways was adopted by the Regional Planning Commission in 1947 and construction began in the early 1950s. The plan hit opposition and funding limitations in the 1970s, and by 2004, only some 61% of the original planned network had been completed.
Interstate 395 (I-395) in Virginia and Washington, D.C., is a 13.79-mile-long (22.19 km) spur route of I-95 that begins at an interchange with I-95 in Springfield and ends at an interchange with US Route 50 (US 50) in Northwest Washington, D.C. It passes underneath the National Mall near the US Capitol and ends at a junction with US 50 at New York Avenue, roughly one mile (1.6 km) north of the 3rd Street Tunnel. Despite its proximity to I-395 in Maryland, the route is unrelated and unconnected.
The Harbor Transitway is a 10.3-mile (16.6 km) shared-use express bus corridor and high occupancy toll (HOT) lanes running in the median of Interstate 110 between Downtown Los Angeles and the Harbor Gateway Transit Center in Gardena, California. Buses also make intermediate stops at 37th Street/USC, Slauson, Manchester, Harbor Freeway, and Rosecrans stations.

A directional interchange, colloquially known as a stack interchange, is a type of grade-separated junction between two controlled-access highways that allows for free-flowing movement to and from all directions of traffic. These interchanges eliminate the problems of weaving, have the highest vehicle capacity, and vehicles travel shorter distances when compared to different types of interchanges.
The El Monte Busway is a 12-mile (19 km) shared-use express bus corridor (busway) and high occupancy toll (HOT) lanes running along Interstate 10 between Union Station in Downtown Los Angeles and Interstate 605 or El Monte Station in El Monte, California. Buses also make intermediate stops at Cal State LA station and LA General Medical Center station. The busway opened in January 1973 to buses only, three-person carpools were allowed to enter in 1976, and the facility was converted to HOT lanes as part of the Metro ExpressLanes project on February 22, 2013.
Interstate 10 (I-10) is a transcontinental Interstate Highway in the United States, stretching from Santa Monica, California, to Jacksonville, Florida. The segment of I-10 in California, also known as the Pearl Harbor Memorial Highway, runs east from Santa Monica through Los Angeles, San Bernardino, and Palm Springs before crossing into the state of Arizona. In the Greater Los Angeles area, it is known as the Santa Monica and San Bernardino freeways, linked by a short concurrency on I-5 at the East Los Angeles Interchange. I-10 also has parts designated as the Rosa Parks and Sonny Bono Memorial freeways. Some parts were also formerly designated as the Christopher Columbus Transcontinental Highway. However, the California State Legislature removed this designation following the passage of a bill on August 31, 2022. I-10 is also known colloquially as "the 10" to Southern California residents (See also California English § Freeways).
Harbor Freeway station is a transit center located on the Harbor Transitway, within the Judge Harry Pregerson Interchange of Interstate 105 and Interstate 110 near Figueroa Street in the neighborhood of South Los Angeles.

Interstate 70 (I-70) is a part of the Interstate Highway System that runs from Cove Fort, Utah, to Woodlawn just outside of Baltimore, Maryland. In Maryland, the Interstate Highway runs 91.85 miles (147.82 km) from the Pennsylvania state line in Hancock east to the Interstate's eastern terminus at its junction with I-695. I-70 is the primary east–west Interstate in Maryland; the Interstate Highway connects Baltimore—and Washington, D.C., via I-270—with Western Maryland. The Interstate serves Frederick and Hagerstown directly and provides access to Cumberland via its junction with I-68 at Hancock. I-70 runs concurrently with its predecessor highway, U.S. Route 40 (US 40), from Hancock to Indian Springs in Washington County and from Frederick to West Friendship in Howard County.
Interstate 15 (I-15) runs north–south in the U.S. state of Utah through the southwestern and central portions of the state, passing through most of the state's population centers, including St. George and those comprising the Wasatch Front: Provo–Orem, Salt Lake City, and Ogden–Clearfield. It is Utah's primary and only north–south interstate highway, as the vast majority of the state's population lives along its corridor; the Logan metropolitan area is the state's only Metropolitan Statistical Area through which I-15 does not pass. In 1998, the Utah State Legislature designated Utah's entire portion of the road as the Veterans Memorial Highway.
The Newhall Pass interchange is a highway interchange at Newhall Pass in Southern California, United States. It is south of the city of Santa Clarita and north of the Los Angeles neighborhoods of Granada Hills and Sylmar. It connects Interstate 5 with California State Route 14. It is officially named in the memory of Los Angeles Police officer Clarence Wayne Dean, who was killed when he was unable to stop before going over a collapsed section of the interchange immediately following the 1994 Northridge earthquake.
A managed lane is a type of highway lane that is operated with a management scheme, such as lane use restrictions or variable tolling, to optimize traffic flow, vehicle throughput, or both. Definitions and goals vary among transport agencies, but managed lanes are generally implemented to achieve an improved operational condition on a highway, such as improving traffic speed and throughput, reducing air pollution, and improving safety. Types of managed lanes include high-occupancy vehicle (HOV) lanes, high-occupancy toll lanes, express toll lanes, reversible lanes, and bus lanes. Most managed lane facilities are located in the United States and Canada, although HOV and bus lanes can be found in many other countries; outside of the US and Canada, many countries use active traffic management that manage all lanes of a highway.
