The scope of the $136m project includes the improvement of the I-15/I-215 interchange near 7200 South and widening of 7200 South by one lane in each direction from I-15 to Bingham Junction Blvd.
It also includes the resurfacing of southbound bridge structures between 12300 South and SR-201 and the replacement of two railroad structures over 7200 South.
Associated project works such as earthwork and grading, drainage, PCC paving, multiple bridge widenings and utility work also form a part of the work package.
Sterling Construction Company CEO Joe Cutillo said: “RLW was selected for this project due, in part, to its design-build capabilities, which include significant engineering expertise and a strong track record of executing effectively on complicated construction elements such as bridge widening and replacement.
“In addition, with its substantial rail-related elements, this project demonstrates our continued focus on expansion into adjacent business lines outside of heavy highway.
“Once completed, the improvements to this very busy stretch of I-15 South will alleviate traffic congestion, enhancing safety and reducing drive times for motorists in the area.”
Initial design work for the project has already started, with construction estimated to begin later this year.
The project is expected to be completed by the end of next year.
