I-15 Southbound Project
Beginning in Spring 2018, the Utah Department of Transportation began work to add a southbound lane to I-15 between S.R. 201 and 12300 South and expand 7200 South, west of the freeway.
New Construction Activities
Last Updated: Friday, January 24, 2020
- Last night, crews changed the configuration for westbound I-215 to southbound I-15 traffic. Westbound to southbound motorists merge directly onto southbound I-15. This configuration and the split loop ramp will be in place the following two weeks and then crews plan to remove the split. Please be alert and attentive driving through this new configuration. Please refer to the map below.
- On Sunday, Jan. 26, crews plan to shift the 5300 South on ramp to the east to accommodate drainage work on the west side of the ramp.
- On Sunday, Jan. 26, crews will begin pile driving bridge structures at the Union Pacific Railroad bridge over 7200 S. This work will begin at 6:30 pm and finish at 5 am. It is anticipated that this work will last three days. Area residents and businesses may notice increased noise and vibrations.
- Beginning as early as Thursday, Jan. 30, crews will begin opening the new southbound lane to traffic. This will be done in sections from the south to the north between approximately 7800 S. and just north of 3300 S. as work is completed.
Despite winter weather conditions, our crews are still working hard on I-15 and 7200 South, both day and night. As a reminder, please drive slowly and carefully through construction zones, especially during winter storm conditions, to ensure your safety and that of other drivers and our crews.
Drivers in the area are advised to use caution in the construction zone and observe all posted signage.
To improve traffic flow and reduce congestion, UDOT is adding a southbound lane to I-15 between S.R. 201 and 12300 South and expanding 7200 South, west of the freeway. The I-15 Southbound project will use $180 million dollars in state funds, which accounts for the environmental study, design and construction. Work will include:
- Adding a lane to southbound I-15 between S.R. 201 and 12300 South in Salt Lake County.
- Widening 7200 South to three lanes in each direction from I-15 to Bingham Junction Boulevard in Midvale.
- Modifying the I-15 interchange at I-215 to improve traffic flow.
