Arizona State Route 87
Arizona State Route 87 (SR 87) is a north–south state highway in central Arizona spanning 272.66 miles (438.80 km) from its southern terminus at Interstate 10 near Picacho in Pinal County to its northern terminus at State Route 264 near Second Mesa in Navajo County.[1] The route traverses diverse terrain, including urban areas of the Phoenix metropolitan region and rural landscapes through the Tonto National Forest and along the Mogollon Rim, serving as a vital link for intrastate travel, tourism, and commerce.[2] Established in 1927 as a connector between State Route 84 and Chandler, SR 87 has undergone numerous extensions and redesignations since the 1920s, evolving from a short local road into a major corridor that originally began near Casa Grande and now reaches the Hopi Reservation in the north.[3] Key segments include the urban stretch through Chandler and Mesa, where it functions as Arizona Avenue and supports heavy commuter traffic, and the scenic "Beeline Highway" portion from the Phoenix area to Payson, known for its steep grades and hairpin turns ascending over 5,000 feet in elevation.[4] In 1996, the section between the Valley and Payson was officially named the Duthie-Martin Highway in honor of two highway patrol officers killed in the line of duty.[3] The highway connects several significant communities and tribal lands, including Coolidge, Fountain Hills, the Salt River Pima–Maricopa Indian Community, Fort McDowell Yavapai Nation, Payson, and Winslow, while providing access to recreational destinations such as state parks, national forests, and the Little Colorado River.[2] It forms part of the National Highway System from its southern end to Payson, facilitating freight movement and serving as a popular route for travelers heading to northern Arizona's high country.[5] Ongoing improvements by the Arizona Department of Transportation focus on pavement rehabilitation, shoulder widening, and safety enhancements to address congestion and terrain challenges along this multi-county corridor.[6]Overview
Route summary
Arizona State Route 87 (SR 87) is a major north–south highway in Arizona that serves as a vital transportation link across the state. Spanning a total length of 271.81 miles (437.48 km) as of 2020, it provides an essential route through diverse landscapes, from desert lowlands to mountainous terrain and high plateaus.[7] The highway's southern terminus is at the interchange with Interstate 10 (I-10) near Picacho in Pinal County, marking the beginning of its northward journey. Its northern terminus is at the junction with State Route 264 (SR 264) near Second Mesa in Navajo County. Along its path, SR 87 traverses five counties: Pinal, Maricopa, Gila, Coconino, and Navajo.[7] As a primary north–south corridor, SR 87 connects the densely populated Phoenix metropolitan area in the south to the rural communities and Native American reservation lands of northern Arizona. The central section through the mountains is commonly known as the Beeline Highway.[3]Designations and maintenance
Arizona State Route 87 (SR 87) is maintained primarily by the Arizona Department of Transportation (ADOT), which is responsible for constructing and maintaining all state highways in Arizona.[8] Specific segments within the city limits of Chandler, Mesa, and Winslow are handled by local municipalities, reflecting the urban integration of the route where city streets overlap with the state designation.[1] The route is designated as part of the National Highway System (NHS) from its southern terminus at Interstate 10 near Picacho northward to Payson in Gila County, supporting critical regional freight and traveler mobility.[9] Officially, SR 87 is known as Arizona Avenue in the urban southern areas through Chandler.[10] In parts of Mesa, it carries the name Country Club Drive.[11] The central mountainous stretch is commonly referred to as the Beeline Highway.[3] While SR 87 lacks a federal scenic byway designation, it plays a vital role in regional connectivity, linking the Phoenix metropolitan area to northern Arizona communities and recreational areas.[12]Route description
Pinal and Maricopa Counties
Arizona State Route 87 begins at its southern terminus, an interchange with Interstate 10 (I-10) near Picacho in rural Pinal County, heading north through expansive farmlands and semi-arid plains characteristic of the region's agricultural landscape.[1] The highway initially traverses sparsely populated areas, providing access to local farms and the nearby Picacho Peak State Park, before approaching the town of Eloy.[13] This southern segment is designated as part of the National Highway System (NHS), facilitating regional freight and commuter traffic. Continuing north for approximately 16 miles, SR 87 enters the city of Coolidge, where it is known locally as Arizona Boulevard and serves as a primary north-south arterial. In Coolidge, the route intersects State Route 287 (SR 287) at Florence Boulevard, marking the eastern terminus of that highway, and overlaps briefly with State Route 84 (SR 84) before the latter branches west toward Casa Grande.[14] Beyond Coolidge, SR 87 proceeds through the Gila River Indian Community near Sacaton, crossing tribal lands amid desert terrain and providing essential connectivity to community facilities and reservation roads.[15] Entering Maricopa County south of Chandler, SR 87 transitions into more developed suburban environments, adopting the name Arizona Avenue as it weaves through the city's commercial and residential districts.[16] The highway intersects State Route 587 (SR 587, also known as the Casa Grande-Chandler Highway) at Riggs Road, offering access to western Chandler and industrial areas.[17] Proceeding northward, it continues as Arizona Avenue through Gilbert, supporting local retail and housing developments, before crossing into Mesa and shifting to Country Club Drive, a bustling multi-lane arterial lined with businesses and educational institutions.[18] In Mesa, SR 87 functions as a vital commuter corridor within the Phoenix metropolitan area, intersecting major east-west routes like U.S. Route 60 (US 60).[1] The urban segment features signalized intersections and sidewalks, accommodating heavy local traffic until reaching its junction with Loop 202 (Red Mountain Freeway) at University Drive, where the highway begins its ascent into the more rural Beeline Highway corridor.[2] This portion underscores SR 87's role in linking southern agricultural zones to the expansive Phoenix suburbs.[1]Gila County
Upon entering Gila County near milepost 223, State Route 87 continues as the four-lane divided Beeline Highway within the Tonto National Forest, ascending through the Mazatzal Mountains. The route splits from the Bush Highway near Saguaro Lake and climbs steadily via steep grades, crossing the Salt River and passing close to the Apache Trail (SR 88) intersection at milepost 222, where the terrain shifts to forested canyons and rugged elevations.[19][1][2] The highway features environmental and safety enhancements, including wildlife crossing structures such as an overpass at milepost 247 to facilitate animal movement across the roadway in the sensitive Tonto National Forest habitat. Post-widening improvements have incorporated upgraded guardrails along steep sections to mitigate risks from rockfalls and vehicle departures, particularly in areas prone to erosion and wildlife activity.[20][21][22] Northbound, SR 87 approaches Payson, serving as the community's main street and intersecting SR 188 at milepost 244 just south of town, followed by SR 260 at milepost 252 within Payson. Beyond Payson, the route tackles the Mogollon Rim ascent through switchbacks and designated scenic overlooks, rising from approximately 5,000 feet at Payson to over 7,000 feet at the rim's ponderosa pine woodlands, offering views of the surrounding canyons and forests.[22][19]Coconino and Navajo Counties
SR 87 enters Coconino County from the south near the Mogollon Rim, descending from elevations around 7,000 feet into the Colorado Plateau through the Coconino National Forest, where the highway winds through ponderosa pine forests and offers scenic views of canyons and rock formations.[22] This segment, spanning approximately mileposts 278 to 338, features a two-lane undivided roadway with gentle curves and passing zones, accommodating moderate traffic volumes of 2,900 to 9,900 vehicles per day, primarily serving recreational travelers and local residents in remote forested areas.[22] The route maintains a rural character with limited services, emphasizing the transition from the Rim's rugged terrain to the broader high-desert landscape of the plateau.[1] Continuing northeast into Navajo County near milepost 338, SR 87 passes through open rangeland and approaches Winslow, a key junction point where it intersects Interstate 40 at milepost 341, facilitating connections to eastern and western Arizona.[22] In this stretch from mileposts 338 to 360, the highway remains a two-lane undivided road with long straightaways across flat, arid terrain dotted by buttes and sparse vegetation, experiencing average daily traffic of 7,100 to 12,200 vehicles and providing essential access to small communities with minimal amenities.[22] Beyond Winslow, the route traverses rural expanses with occasional pullouts for viewpoints, crossing the Little Colorado River near milepost 361 and entering the Hopi Reservation, where it ascends gradually toward Second Mesa.[1] On the Hopi Reservation from milepost 361 to its northern terminus at milepost 391, SR 87 climbs to elevations over 6,000 feet on the mesas, passing near traditional Hopi villages such as Shungopavi and providing panoramic vistas of the surrounding high desert and ancient pueblos.[1] This final segment continues as a two-lane undivided highway, supporting low-volume traffic of around 1,200 to 3,100 vehicles daily while serving isolated communities and cultural sites with limited roadside development to preserve the reservation's integrity.[22] The road ends at the junction with SR 264 near Second Mesa, marking the conclusion of its journey through northern Arizona's diverse plateau landscapes.[1]History
Early development and designation
Arizona State Route 87 was established in 1927 as part of Arizona's numbered state highway system, initially routing as an unpaved dirt road from near Casa Grande to Mesa to connect key communities in Pinal and Maricopa Counties.[3] This alignment followed existing paths through agricultural lowlands, serving as an essential extension of the developing network under the Arizona Highway Department, which aimed to link southern Arizona's farming regions to larger markets.[23] In 1927, following the reorganization of the Arizona Highway Department into the Arizona State Highway Commission, SR 87 was designated from State Route 84 near Casa Grande to Chandler, integrating it more closely with the Southern National Highway and other early routes, enhancing connectivity along the Salt River Valley.[23] Throughout the 1920s to 1940s, SR 87 functioned as a vital corridor for early automobile travel and freight hauling, facilitating the transport of produce and goods from Pinal County farms to Phoenix and beyond.[23] The highway supported the rise of auto tourism in southern Arizona, linking towns like Coolidge and Chandler while promoting economic growth in the region amid increasing vehicle adoption.[24] Initially built as a basic two-lane road with minimal grading, it traversed flat terrain that occasionally challenged maintenance due to seasonal water flows in the Pinal County lowlands.[23]Major extensions and reroutings
In 1959, the Arizona Department of Transportation extended State Route 87 northward from Mesa to Strawberry Junction via a new cutoff known as the Beeline Highway, which provided a more direct path through the Mazatzal Mountains and bypassed a winding section of the older Bush Highway alignment near Saguaro Lake, shortening the overall distance by approximately three miles.[3][25] This extension connected the Phoenix Basin more efficiently to the Mogollon Rim region, replacing slower routes and facilitating increased travel to northern Arizona.[26] The Beeline Highway moniker was adopted around the same time to reflect the route's straight-line efficiency as a shortcut from Mesa to Payson, contrasting with the more circuitous alternatives available prior to its construction.[3] During the 1950s and 1960s, additional reroutings realigned SR 87 through Chandler and Mesa to bypass congested older paths, incorporating straighter urban corridors like Arizona Avenue in Chandler and improving connectivity southward toward Coolidge.[26] These changes, combined with the northern expansions, added roughly 100 miles to the highway's total length over the period. Further extension occurred in 1968, when SR 87 was lengthened northward from its previous endpoint near Winslow to its current terminus at SR 264 near Second Mesa, absorbing segments of the former State Route 65 and incorporating roads within the Hopi Reservation to serve tribal communities and enhance access to the Colorado Plateau.[4] This completion established the modern north-south corridor spanning from the Sonoran Desert to the high plateaus, supporting economic and recreational travel across diverse Arizona landscapes.[4]Infrastructure improvements
The widening of the Beeline Highway portion of SR 87 to a four-lane divided highway from Mesa to Payson was a major infrastructure project undertaken between 1990 and 2001, transforming the route from a predominantly two-lane road into a higher-capacity corridor to accommodate growing commuter and tourist traffic.[25][27] By 1983, nearly half of the highway had already been expanded to three or four lanes, with the remaining sections, including northbound lanes built on new alignments, completed by 2001, including the final bridge and realignment at Kitty Joe Canyon.[25] These upgrades significantly increased traffic capacity by 75 percent and reduced the accident rate by 65 percent compared to the pre-widening era, when crash rates were 50 percent above the national average, while also cutting travel times along the corridor.[28][25] In Gila County, the 1990s saw targeted enhancements such as the addition of passing lanes (for example, at mileposts 213 to 216.7) and curve realignments (such as at milepost 216.2 to 216.5) to improve safety and flow amid rising tourism and regional commuting demands.[27] These measures included guardrail upgrades and rock-fall mitigation, addressing the challenging mountainous terrain and reducing hazards in remote sections.[27] The project was funded through a combination of state resources and federal highway aid, reflecting broader efforts to modernize Arizona's rural highways.[23]Recent developments
21st century projects
In the early 2000s, the Arizona Department of Transportation (ADOT) completed the long-term widening of the Beeline Highway section of State Route 87 (SR 87) from Mesa to Payson, transforming it into a four-lane divided highway to accommodate growing traffic volumes and improve safety and efficiency. This project culminated in 2001 with the construction of the final bridge and realignment over Kitty Joe Canyon in Gila County, marking the end of decades of phased expansions that began in the 1950s and addressed challenging mountainous terrain in the Mazatzal Mountains.[25] Although earlier phases from the late 20th century laid the groundwork by widening segments through Maricopa County, the 2001 completion extended these improvements northward, reducing travel times and enhancing connectivity to the Mogollon Rim area. From 2011 to 2012, ADOT collaborated with the Arizona Game and Fish Department to install wildlife underpasses and fencing along SR 87 within Tonto National Forest, primarily targeting reductions in animal-vehicle collisions involving Sonoran desert tortoises while benefiting species like deer and javelina. The initiative included ungulate-proof fencing along approximately two miles near mileposts 204–206 and modifications to existing culverts as underpasses, resulting in documented decreases in wildlife crossings at grade and improved habitat connectivity across the highway. Evaluations post-installation confirmed efficacy in guiding animals to safe passages, with collision rates dropping significantly in treated segments.[29]Ongoing construction as of 2025
As of November 2025, several construction projects on Arizona State Route 87 (SR 87) remain active or are imminent, aimed at enhancing safety, accessibility, and pavement condition amid growing traffic volumes from prior widenings in the region.[6] In Payson, the Arizona Department of Transportation (ADOT) is conducting a $12.2 million street improvement project along SR 87 between Green Valley Parkway and Crackerjack Road, which includes the area near the Event Center and extending toward Flowing Springs Road. Sidewalk reconstruction, driveway adjustments, and ADA-compliant ramp installations began in early August 2025, with alternating lane closures occurring nightly from 8 p.m. to 7 a.m., Sunday through Friday, to minimize daytime disruptions. The full repaving phase, involving removal and replacement of the top pavement layer along with stormwater and utility upgrades, is scheduled to start in spring 2026 and conclude by late 2026.[6][30] Near Coolidge, intersection improvements at SR 87 and Kleck Road, which added left-turn lanes in both directions and widened the roadway, were completed in summer 2025 following a start in February; these enhancements address congestion at this key access point for local traffic.[31] North of Fountain Hills, ADOT conducted resurfacing efforts between Vista Del Oro Road and Fort McDowell Road, resulting in alternating lane closures and narrowing to one lane in each direction during July 2025; these works improved pavement condition and resilience against seasonal weather impacts.[32] Additionally, potential enhancements to the SR 87 and SR 260 interchange in Payson, such as adding a right-turn lane on northbound SR 87, have been incorporated into ADOT's 2026-2030 Five-Year Construction Program following public input sessions held in early 2025; design work is slated to advance in fiscal year 2026 to accommodate increasing regional traffic.[33][34]Junctions
Major highway intersections
Arizona State Route 87 begins at its southern terminus with a diamond interchange at Interstate 10 near Picacho, enabling seamless connectivity for northbound traffic from the major east-west corridor serving Tucson, Phoenix, and points beyond. This interchange, reconstructed in 2019 to include longer acceleration and deceleration ramps, enhances safety and efficiency for vehicles entering SR 87 from I-10's eastbound and westbound directions.[35] Within the Phoenix suburbs, SR 87 links to Loop 202 (Red Mountain Freeway) in Mesa via a partial interchange at Exit 13, which primarily accommodates southbound movements from the loop freeway onto SR 87 (Country Club Drive) while directing northbound SR 87 traffic onto the eastbound loop. This configuration supports suburban commuting and regional circulation in the densely populated East Valley area.[36] In central Mesa, SR 87 crosses U.S. Route 60 at an at-grade signalized intersection, integrating the north-south route with the east-west Superstition Freeway and providing essential linkage for local and through traffic between the Phoenix metropolitan area and eastern Arizona destinations.[37] North of the Valley, SR 87 intersects State Route 260 in Payson at an at-grade intersection, serving as a critical gateway for travelers accessing the broader northern Arizona network, including routes to the White Mountains and Mogollon Rim via the concurrent SR 87/SR 260 segment.[22] At its northern extent near Winslow, SR 87 crosses Interstate 40 via a full diamond interchange at Exit 257, facilitating direct connections to the transcontinental east-west highway and U.S. Route 180, which supports freight and tourism flows across Navajo County.[38]Interchange list
