Challenge: The Arizona Department of Transportation (ADOT) was seeking to construct the Loop 202 South Mountain freeway. The 22-mile-long freeway is essential to serving the Phoenix community and the traveling public. The project is the largest in the state’s history and the goal was to use a design, build, and maintain (DBM) procurement method to reduce project costs to deliver the eight-lane freeway.
Solution: YSMA, an HR Green company based in Tempe, was selected to be part of the design-build project team. YSMA/HR Green led the Intelligent Transportation System (ITS) portion of the project and was also responsible for designing 11 miles of ADOT’s freeway management system (FMS) infrastructure and eight traffic signals. The FMS portions of the project included fiber optic communications, dynamic message signs (DMS), closed-circuit television (CCTV), ramp meters, and detection stations.
YSMA/HR Green also facilitated the FMS design between the various disciplines specifically traffic, structures, and landscape design. The traffic signal and ITS facilities accommodated overhead signs and lane markings with respect to ramp meters.
Areas bordering the Gila River Indian Community (GRIC) presented an opportunity to leverage ADOT FMS infrastructure for Gila River telecommunications needs. YSMA/HR Green spearheaded the coordination of those efforts between GRIC and ADOT to facilitate the design of GRIC Telecommunication facilities alongside the ADOT FMS infrastructure.
Benefit: The Loop 202 South Mountain freeway project was a culmination of a 35-year effort on the part of ADOT to provide freeway connectivity to the area surrounding South Mountain. It provides a safer and much-needed route for growth in the community, utilizing state-of-the-art traffic innovations. The design-build approach for the project saved ADOT more than $100M in construction costs. The project also paved the way to provide broadband telecommunication to the Gila River Indian Community.
