IH 15 Tech Corridor

In order to alleviate traffic congestion through Utah’s rapidly growing Silicon Slopes area, UDOT allocated $450 million to improve a section of I-15, also known as the Tech Corridor. CobbFendley oversaw the coordination and utility design efforts to relocate 20 utility companies (both public and private) along 6.5 miles of I-15. CobbFendley supplemented existing 30% design utility information, providing Quality Levels D, C, B and A SUE services for the design-build project, which aims to improve travel times by expanding NB and SB lanes from 4 to 6, replacing 13 bridges, and adding shared use facilities to new frontage roads. CobbFebdley’s Utah team worked with design engineers to accurately supplement utility location data, ultimately completing 325 test holes and providing Level B SUE location designation for 16,000 linear feet of identified utilities. In addition, the team performed 20,000 linear feet of Levels C and D SUE services through painstaking records research and verification.
