MC85 and Avondale Boulevard Widening
This federally funded multi-jurisdictional project involved ADOT, MCDOT, Avondale, and Union Pacific Railroad (UPRR). The project widened the intersection serving nearly half a million cars to Phoenix International Raceway events.
YSMA engineered the project from conceptual stage to design and through construction by taking into considerations restrictions posed by irrigation structures, railroad, right of way and the needs of adjacent trucking facility whose access was impacted.
The project demanded intense coordination with UPRR and expertise in traffic signal and railroad operations. During construction, UPRR unexpectedly raised their track elevations which posed a challenge to the rest of the intersection construction. This required a quick redesign of the intersection to prevent schedule overruns.
