U.S. Route 60 (US 60) is an east–west United States Highway within Arizona. The highway runs for 369 miles (594 km) from a junction with Interstate 10 near Quartzsite to the New Mexico State Line near Springerville. As it crosses the state, US 60 overlaps at various points: I-17, I-10, SR 77, SR 260, US 191, and US 180. Between Wickenburg and Phoenix, the route is known as Grand Avenue (or the Phoenix–Wickenburg Highway). From Tempe to Apache Junction, it is known as the Superstition Freeway.

Route description

I-10 to Wickenburg

The western terminus of US 60 is located at an interchange with I-10 east of Quartzite. It heads northeast from this junction to Vicksburg Junction where it curves towards the east. It continues to the east to Hope where it intersects SR 72. East of Hope, the highway briefly curves towards the north-northeast before curving towards the northeast. It continues this direction until it reaches Aguila. The highway heads east to an intersection with SR 71 after passing through Aguila. US 60 continues towards the east until it reaches Wickenburg and an intersection with US 93. From Wickenburg, the highway heads towards the southeast towards Phoenix. It has an intersection with SR 74 in Morristown as it continues towards the southeast.

Grand Avenue

As US 60 enters the Phoenix metropolitan area, It intersects Loop 303 in Surprise where it becomes Grand Avenue as it continues southeast. It continues to a junction with Loop 101 (Agua Fria Freeway) in Peoria before heading through Glendale. The highway enters the Phoenix city limits and continues towards the southeast until it reaches an interchange with 27th Avenue near Thomas Road.

Improvements to the Grand Avenue portion of US 60, which were included in the Maricopa Association of Governments' 20-year Regional Transportation Plan, have been made. Among such improvements is the reducing of many of the busiest six-legged intersections to four-legged intersections by constructing overpasses, underpasses, and access roads.

I-17/I-10 concurrencies

After briefly heading south along 27th Ave., US 60 turns left onto Thomas Rd. for 14 mile (0.40 km) until it reaches I-17. At I-17 the highway begins to run concurrently with I-17 towards the south. It passes through an I-10 interchange known as "The Stack." US 60 continues to run concurrent with I-17 around the Durango Curve and continues east until it again reaches I-10 at the interchange known as "The Split." US 60 begins to run concurrently towards the east with I-10 after the interchange. Along the freeway, US 60 passes along the south side of the airport and over a bridge traversing the Salt River. Once over the river, the freeway continues towards Tempe to an interchange with SR 143. The freeway curves back towards the south following the SR 143 interchange.

Superstition Freeway

After the curve, I-10 and US 60 part ways in Tempe, with I-10 continuing towards the south and US 60 now heading east along the Superstition Freeway. The freeway continues towards the east to a second interchange with Loop 101 (Price Freeway). The freeway enters Mesa city limits after the interchange as it continues towards the east to the SuperRedTan interchange with Loop 202. The freeway enters the city limits of Apache Junction in Pinal County as it continues eastbound. The freeway portion of the highway ends in Apache Junction as US 60 curves towards the southeast.

The highway continues towards the southeast passing through Gold Canyon to an interchange with SR 79 at Florence Junction. US 60 curves towards the east at this junction as it heads to Superior and an interchange with SR 177. From Superior the highway begins to head towards the northeast to Miami and Claypool. It continues to a junction with SR 188 before passing through Midland City and turning towards the south towards Globe. US 60 curves back towards the east in Globe and continues to an intersection with US 70 and SR 77. US 60 heads northeast from the intersection concurrent with SR 77. The two highways curve towards the north before curving back towards the northeast as they head towards Show Low. As the highway continues towards the northeast it enters the San Carlos Indian Reservation. Within the reservation, the highway goes through a series of hairpin turns as it enters the Salt River Canyon. After descending into the canyon, the highway passes over the Salt River and enters the Fort Apache Indian Reservation. The highway continues towards the northeast and enters Navajo County before reaching an intersection with SR 73. It continues northeast from this intersection to the city of Show Low.

In Show Low, US 60 intersects SR 260 and briefly runs concurrently with SR 260 as it heads northeast through the city. The concurrency with SR 77 also ends in Show Low as SR 77 heads north to Snowflake and US 60 continues towards the east. US 60 leaves the Show Low city limits and heads east to a junction with SR 61 which heads northeast towards Concho. US 60 continues east from this intersection before curving towards the southeast as it heads towards Springerville.

As it enters the Springerville city limits, it intersects and begins to run concurrently with US 180 and US 191. The three highways continue along the same alignment through Springerville, passing over the Little Colorado River. As the three highways continue through the city, they eventually split with US 180 and US 191 heading south towards Alpine and US 60 continuing towards the east. US 60 continues towards the east leaving the Springerville city limits and crossing over the state line into New Mexico. [1] [3]

Existed1970–1992

In 1927, what is now US 60 was signed as or roughly followed by SR 74 between the California border near Ehrenburg and Wickenburg, US 89 from Wickenburg to Florence Junction, US 80 from Phoenix to Florence Junction, US 180 from Florence Junction to Globe and US 70 between Springerville and the New Mexico border. The segment of highway between Springerville and Globe had not been constructed yet. [4] [5] [6] US 60 was extended into Arizona on June 8, 1931, from its original western terminus at US 66 in Springfield, Missouri. [7] While what is now US 60 was under construction between Globe and Springerville, US 60 was temporarily routed down SR 73 as US 60T through San Carlos and McNary. The current route through Show Low was completed sometime between 1935 and 1938. [8] US 60 through Arizona has had far fewer major changes than some other U.S. routes, but one notable example is being replaced by Interstate 10 between Los Angeles, California, and the highway's current terminus near Quartzsite. (The Arizona section of this route was decommissioned in 1982. [9] )

US 60 is now the only U.S. Route to serve Phoenix. US 70 (decommissioned 1969), US 80 (decommissioned 1977) & US 89 (decommissioned 1992) have all been truncated outside of Phoenix. The only other major change was being realigned from an "in-town" route along city arterials through Mesa, Tempe, and Phoenix to the old SR 360 alignment a few miles south and merging with I-10 and I-17 into Downtown Phoenix. [10]

In 1949, the Pinto Creek Bridge won an Annual Award of Merit for being the "most beautiful steel bridge", given by the American Institute of Steel Construction. [10]

In 1952, the Claypool Tunnel was bypassed by the Queen Creek Tunnel to the north, upgrading from a simple 'hole in the rock' type tunnel to a more modern tunnel. [10]

Recent improvements

In recent years, Arizona Department of Transportation (ADOT) has been working to widen and improve US 60 through the Metropolitan Phoenix Area, as it is one of the area's principal freeways. Along the Superstition Freeway segment in the East Valley between I-10 and Loop 202, ADOT has completed its project of adding additional general purpose lanes (6 total plus an HOV in each direction), adding auxiliary lanes between exits, improving sound barriers, replacing signs, improving lighting conditions, adding rubberized asphalt to reduce noise, adding variable message signs, installing cameras, and adding traffic sensors. [11] A new partial interchange at Meridian Road, along the MaricopaPinal county line, opened in October 2015. [12]

US 60 Arizona 1956 West.svg US 60 Arizona 1956 East.svg
Directional colored shields found on US 60 in Arizona during the 1950s.

Along the Grand Avenue segment in Phoenix, ADOT has been widening portions of Grand Avenue in addition to constructing additional overpasses and underpasses at six former six-way intersections to improve traffic flow along US 60 in the Northwest Valley. [13]

ADOT is currently in the study phase of adding additional lanes between Loop 101 and Loop 303 in the far West Valley.

Future

Due to rapid growth in the far eastern Phoenix suburbs within Pinal County and increasing road congestion in the Gold Canyon area, ADOT has begun to study potential freeway-grade realignments of US 60 past the current eastern terminus of the Superstition Freeway in Apache Junction. The new freeway alignment would bypass the existing at-grade section of US 60 through Gold Canyon, and would either rejoin the existing alignment southeast of town (in the vicinity of the Arizona Renaissance Festival grounds) or at the newly constructed freeway-grade junction with SR 79 at Florence Junction.

Notes

  1. The mileposts were not renumbered after the western leg was truncated, so they begin at milepost 30.89. Mileposts for US 60 are not logged on overlaps with Interstate highways, except at the junction of I-10 and I-17.
  2. Only the freeway portion of US 60 east of the I-10 interchange has exit numbers, except for a few exits on the lower section of Grand Avenue, and the interchanges with SR 79 and SR 177. All other segments are standard divided or undivided highways with uncontrolled access. [16]

An unsigned U.S. Route 60X is also listed by ADOT is divided into two discontinuous segments, both of which are located within Maricopa County in the Phoenix area. Both sections of US 60X were portions of the pre-freeway alignment of US 60 between Apache Junction and central Phoenix. [23]

US 60X begins near Grand Avenue and Thomas Road at exit 160, where US 60 leaves Grand Avenue for Thomas Road. It then follows Grand Avenue southeast over I-17/US 60, terminating at an intersection with 18th Avenue and Willetta Street. [24]

The eastern segment of US 60X picks up at Sossaman Road, traveling east across Main Street/Apache Trail, crossing Loop 202 and Ellsworth Road before terminating at Meridian Drive, at the Pinal County line. [24] [25]

Major intersections

The eastern segment of US 60X has posted mile markers that likely correspond to the former alignment of US 60.

Interstate 17 (I-17) is a north–south Interstate Highway located entirely within the U.S. state of Arizona. I-17's southern terminus lies within Phoenix, at Interstate 10, and its northern terminus is in Flagstaff, at Interstate 40. The majority of I-17 is known as the Arizona Veterans Highway. In the Phoenix metropolitan area, it is mostly known as the Black Canyon Freeway, however the southern 4.16 miles (6.69 km) is part of the Maricopa Freeway. The portion of the highway south of Cordes Lakes was built along the alignment of SR 69, while the northern part was built along old SR 79's alignment. I-17 is one of the most scenic Interstate Highways as it gains more than a mile in altitude between Phoenix at 1,117 feet (340 m) and Flagstaff at 7,000 feet (2,100 m). The highway features several scenic view exits along its route that overlook the many mountains and valleys found in northern Arizona.

State Route 85 is a 128.86-mile-long (207.38 km) state highway in the U.S. state of Arizona. The highway runs from the United States-Mexico border near Lukeville to the north ending at Interstate 10 (I-10) in Buckeye. The highway also intersects I-8 in Gila Bend and serves as a connector between I-8 and I-10 and for travelers between Phoenix and Yuma as well as San Diego. SR 85 between I-10 and I-8, as well as I-8 between SR 85 and I-10 in Casa Grande, is touted as a bypass of the Phoenix area for long-distance travelers on I-10.

State Route 79, also known as the Pinal Pioneer Parkway, is a 58.40 mi (93.99 km) long state highway in the U.S. state of Arizona. It serves as the main route through the town of Florence, which is also the county seat of Pinal County. Although the highway has been part of the state highway system since at least 1926, it was not designated as SR 79 until 1992. The highway was previously a section of U.S. Route 80 and U.S. Route 89 between Phoenix and Tucson, until both highways were decommissioned in 1977 and 1992 respectively. SR 79 is also the only state highway in Arizona that has a business route, which is SR 79 Business through downtown Florence. SR 79 is also notable for being the location where cowboy western actor Tom Mix lost his life in a car accident on October 14, 1940.

State Route 89A is an 83.85-mile (134.94 km) state highway that runs from Prescott north to Flagstaff in the U.S. state of Arizona. The highway begins at SR 89 and heads northward from Prescott, entering Jerome. From Jerome, the route then heads to Cottonwood and Sedona. The highway is notable for its scenic value as it passes through Sedona and the Oak Creek Canyon. The route then enters Flagstaff, where it crosses Interstate 17 (I-17) and I-40. The highway ends at I-40 Business in Flagstaff. What is now SR 89A became a state highway in the late 1920s as SR 79. The highway was extended and improved several times through 1938. SR 79 was renumbered to U.S. Route 89A in 1941 and then to SR 89A in the early 1990s.

Arizona State Route 143, also known as SR 143 and the Hohokam Expressway, is a north–south and access-controlled freeway in Maricopa County, Arizona, that runs from a junction with Interstate 10 at 48th Street in Phoenix to McDowell Road.

Arizona State Route 303 state highway in Arizona, United States

Arizona State Route 303, also known as Loop 303 or Bob Stump Memorial Parkway and formerly called Estrella Freeway, is a freeway that serves the northwestern portion of the Phoenix area. The freeway, originally a two-lane rural highway, was maintained by Maricopa County in central Arizona serving the far western suburbs of the Phoenix metropolitan area until 2004 when the Arizona Department of Transportation again took the control of upgrading the interim road to a freeway. In 2004, it was renamed "Bob Stump Memorial Parkway" to honor former Arizona congressman Bob Stump.

SR 86 is the primary east–west highway through the Tohono O'odham Nation.

State Route 88 is a 45.67 mi (73.50 km) long state highway in the U.S. state of Arizona. It runs from U.S. Route 60 in Apache Junction through desert terrain to SR 188 near Roosevelt Dam. Following the Salt River for much of its length, the section east of Tortilla Flat is known as the Apache Trail and is part of the National Forest Scenic Byway system. The Apache Trail was built in the mid-1920s and the number 88 was assigned in 1927. An eastern extension of SR 88 to Globe was redesignated as SR 188 on August 20, 1999.

State Route 73, also known as SR 73, is a U-shaped state highway, though it is signed north–south, primarily serving the Fort Apache Indian Reservation in eastern Arizona.

Arizona State Route 187 State highway in Arizona, United States

State Route 187, also known as SR 187, is a state highway in south-central Arizona traveling from State Route 387 north of Casa Grande north to its junction with State Route 87 near Sacaton. The entire stretch of road runs in the Gila River Indian Reservation and is approximately 5 miles (8.0 km) long. It is a short-cut for traffic heading toward the southeast valley of Phoenix in case of an accident on westbound Interstate 10.

State Route 177 or SR 177 runs in a north–south direction from Superior, Arizona to Winkelman, Arizona. It ends at two junctions, US 60 to the north and State Route 77 to the south. The southern half of this road runs alongside the Gila River and the Copper Basin Railroad.

Arizona State Route 93, abbreviated SR 93, was a state highway in Arizona that existed from 1946 to 1991. The route was co-signed with other highways along nearly all of its route from Kingman to the border at Nogales. SR 93 was the original designation for the highway from Kingman to Wickenburg, which was built in 1946. In 1965, the northern terminus of the state route was moved south to an unnamed desert junction with U.S. Route 89 just north of Wickenburg, and the southern terminus of U.S. Route 93 was moved south to the US 89 junction. The Arizona Highway Department sought U.S. Highway status for SR 93 across the rest of the state, but the proposal was never granted by AASHTO. On December 17, 1984, the SR 93 designation was removed south of the Grand Avenue/Van Buren Street/7th Avenue intersection in Phoenix. The route was completely decommissioned in 1991.

U.S. Route 93 in the state of Arizona is a United States Numbered Highway that begins in Wickenburg and heads north to the Nevada state line at the Mike O'Callaghan–Pat Tillman Memorial Bridge.

The metropolitan area of Phoenix in the U.S. state of Arizona contains one of the nation's largest and fastest-growing freeway systems, boasting over 1,405 lane miles (2,261 km) as of 2005.
