South Mountain Freeway

Three of the state's major freeway and highway projects have earned regional awards in a national transportation competition that focuses on efforts to strengthen communities, improve the quality of life and foster a more efficient economy. The American Association of State Highway and Transportation Officials (AASHTO) announced the Arizona Department of Transportation projects, including the new Loop 202 South Mountain Freeway in the Phoenix area, have won first place awards in the organization's west region.

After spending time in temporary nurseries, more than 1,000 saguaro cactuses, palo verde trees and other native plants removed from the path of the Loop 202 South Mountain Freeway are now being used to grace the 22-mile corridor. Other plants salvaged and being replanted for the Arizona Department of Transportation's largest-ever highway project include ironwood and mesquite trees, as well as ocotillo and barrel cactuses.

After construction on 40 bridges over more than two years, workers have placed the final girder for the Loop 202 South Mountain Freeway, the Arizona Department of Transportation's single largest-ever freeway construction project. Crews with Connect 202 Partners, the freeway developer, lowered the 91-ft., 77,000-lb.

Two years after construction began on an interchange connecting Interstate 10 and the Loop 202 South Mountain Freeway, crews have placed the final bridge girders needed for this huge Arizona Department of Transportation project in west Phoenix. The milestone occurred when Connect 202 Partners, the developer of the South Mountain Freeway, placed 21 concrete support beams, measuring up to 128 ft.

With all bridge girders in place, frontage road construction under way and an overpass built over railroad tracks, among other milestones, Loop 202 South Mountain Freeway construction continues advancing along the 59th Avenue alignment south of Interstate 10 (Papago Freeway) in west Phoenix.

The Loop 202, Arizona's South Mountain Freeway, will add 22 mi. of freeway to the existing Phoenix metropolitan transportation system, easing traffic congestion and connecting the east and west valleys. Major construction began in early 2017. The project is scheduled for full completion in 2020, although traffic is expected to be using the freeway earlier.

Nearly two years after the first girder was set on Loop 202 South Mountain Freeway, the last support beam has been installed for the Dobbins Road interchange, marking the final girder placed on the Salt River segment of the freeway in the Laveen area.

The largest structures on the Arizona Department of Transportation's Loop 202 South Mountain Freeway project are nearly complete, with crews finishing the concrete decks of two half-mile-long bridges that will carry traffic over the Salt River in the growing southwest Valley.

Two hundred and ninety-two. That's the number of concrete girders installed on two Loop 202 South Mountain Freeway bridges spanning the Salt River between Broadway Road and Southern Avenue in the southwest Valley. It's also nearly a third of the 1,000 girders to be installed on 40 bridges throughout the 22-mi.

The team building the Loop 202 South Mountain Freeway, Arizona's largest single highway project ever, has awarded more than $100 million in contracts to local small businesses run by socially and economically disadvantaged groups, including minorities and women.

The Arizona Department of Transportation is making significant progress on two big projects. Girder placement has taken place for both the South Mountain Freeway interchange at 24th Street and the SR 87 interchange along the I-10 project.
