Project Scope

The project is located in Pima County, Arizona, at the intersection of I-10 and Ruthrauff. This stretch of road was named after the Chief Engineer of the City of Tucson, John Mosheim Ruthrauff, whom became one of the first to design and pave the streets of Tucson, Arizona in the years 1912-1917. Ruthrauff offers transportation from Interstate 10 to central and northern Tucson, but due to conflicts with an existing railroad crossing, traffic often comes to a standstill as various train cars arrive. This project aims to relieve traffic tension from this area by creating a overpass above the Union Pacific Railroad and widening the road to four lanes in both directions. 


The scope of work includes furnishing of all labor, materials, equipment, fixtures and services required for the widening of the offramp on each side of the existing roadway, drilled shaft foundations to support the widened four lane roads, new concrete pier and abutment walls on each side of the existing bridge, crash tested barrier railing, removing the chip seal overlay, providing a new polymer epoxy deck overlay, asphalt paving, embankment construction, striping, guardrail, and miscellaneous related work.
