Construction for interchange upgrades is underway at 6200, 10400, and 12600 South.  Work activities began in May 2020 with completion anticipated for late 2021.

As one of our valley’s largest north-south corridors, Bangerter Highway moves an average of 58,000 vehicles per day. With continued growth on the west side of the Salt Lake Valley, that number is expected to double by 2040 and without major improvements, delays will increase by four times over the next twenty-five years.


The Utah Department of Transportation (UDOT) is making major improvements at various intersections along Bangerter Highway to reduce travel times and congestion, connect communities, and improve overall safety along the corridor. Bangerter operated using a series of traffic signals at a majority of its intersections, causing significant congestion in recent years. This congestion also exists for cross traffic moving east-west. To meet the current and future needs of drivers and the nearby communities, UDOT is replacing traditional intersections with grade-separated interchanges. Grade-separated interchanges allow one street to pass over the other. This separation allows Bangerter to free flow and the cross street to flow more efficiently. By removing traffic signals and creating fewer interruptions, traffic will move more freely and at speeds that are more consistent in all directions.
