PROJECT UPDATE Jan. 15, 2021


As early as Friday, Jan. 22, 2021, UDOT will implement a long-term, east-west closure of 12600 South across Bangerter Highway. This closure will remain in place through August 2021, and will facilitate construction of the grade-separated interchange. Designated detour routes will be signed for drivers navigating the area.

Although east-west traffic will be restricted, northbound and southbound drivers on mainline Bangerter Highway will have free-flow travel with the permanent removal of the traffic signal. Right turn movements to/from 12600 South will also be allowed.

The decision for the east-west closure was made in partnership with UDOT and Riverton City due to the complexity of the new interchange. To construct the underpass on 12600 South, crews will build from the “top down,” starting with bridge components first, followed by excavating the underpass. This approach will emphasize safety for both the traveling public and workers and allow efficient interchange construction.

Bangerter Highway

Northbound on- and off-ramp construction

Crews continue to prepare for the Jan. 22, 12600 South east-west closure and Bangerter north-south traffic shift. These activities include asphalt and concrete paving on the northbound ramps with concrete paving, fence installation, curb and gutter placement


Southbound on- and off-ramp construction

Crews have shifted all traffic to the west side of Bangerter Highway. Drivers are advised to note changing traffic patterns.


Crews continue work activities to construct the southbound on- and off-ramps on the west side of Bangerter Highway.


12600 South utility relocations

Crews are performing utility relocations directly on 12600 South and on east and west Bangerter Highway as preparatory work for the new interchange.

Plan Ahead

Construction activities are ongoing day and night. Residents, businesses, and drivers should be aware of trucks entering and exiting the work zone, as well as noise, dust, vibration, and nighttime construction lighting.


Drivers and pedestrians are advised to note reduced speeds of 45 mph, changing traffic patterns, and on-site construction activities and equipment while navigating in the area.


As part of its efforts to keep traffic moving on Bangerter Highway now and into the future, UDOT will build freeway-style interchanges at 6200, 10400, and 12600 South. This is a continuation of UDOT’s multi-year effort to upgrade Bangerter Highway and the east-west arterial roads in order to meet the traffic demands of western Salt Lake County.


During these unprecedented times, safety remains our top priority and we have been following the Governor’s mandate to take bold, aggressive steps to slow the spread of disease. Our project team is working hard to maintain a heightened awareness and proper social distancing methods while still moving forward with construction activities.
