Project Overview

Similar to Sundt’s Ina Road project, the new interchange will reduce delays and improve safety on Ruthrauff Road and on El Camino del Cerro west of I-10 by carrying traffic over the freeway and Union Pacific Railroad tracks running parallel to the interstate.

The project includes widening I-10 to four lanes in each direction and reconstruction of the traffic interchange. Other improvements include widening Ruthrauff Road and El Camino del Cerro to two lanes in each direction near I-10, reconstructing the I-10 frontage roads to connect to the new interchange and other miscellaneous work including constructing concrete barriers, storm drain, guardrail, granite mulch, landform graphics, signing and pavement marking.

Prior to the start of construction a large area had been identified as having the potential for archaeological findings. The project team opened up the areas of interest to archaeologists to clear them before we started mass excavation.

This is an important project for the Tucson area. The new interchange will allow traffic to move more quickly through the area, and we’re improving safety because drivers will no longer have to cross the railroad tracks.
