Mountain View Corridor

West Valley City, Utah

As one of the Utah Department of Transportation (UDOT)’s top projects of 2017, phase two of the Mountain View Corridor project added 2.5 miles of greenfield roadway from 5400 South to 4100 South in West Valley City and included the completion of 14 mainline bridges, seven pedestrian bridges, intersection reconstruction, and safety improvements in impacted areas. The completion of this latest phase of the project focused on forward compatibility to accommodate future build-out of the corridor, and quality design for long-lasting, low-maintenance infrastructure.

A phased construction approach was implemented for this project to address immediate short-term regional transportation needs while providing a long-term solution.

Michael Baker, as part of the Ralph L. Wadsworth/Staker Parsons Companies design-build team, served as the lead designer for the second phase of the project, which included the full design and construction of a new greenfield segment of the corridor, including a roadway, structures and a shared-use path, to allow for future growth and mobility.

Future construction will build out the remainder of the corridor, including a transit solution and enhancement of initial construction by adding more lanes, a collector distributor system and interchanges. The next phase of construction to expand the corridor from 4100 South to S.R. 201 will begin in 2019. In the meantime, the extension project into Utah County from SR-73 to 2100 North will begin in 2018.

The corridor will evolve into a free-flowing freeway as improvements are made in subsequent construction stages. Once all phases are completed, the Mountain View Corridor will be a 35-mile freeway from I-80 in Salt Lake to SR-73 in Utah County. It will also provide an alternative route to I-15 for commuters and residents.


“Extending this vital transportation corridor while maintaining existing east-west connector streets helps to ensure that the fabric of established neighborhoods remain intact and that residents have easy and safe access to neighborhood schools.”
