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.

Great news: The I-15 Southbound Team is pleased to announce the opening of the new southbound lane from S.R. 201 to 7800 S. The lane is now open to keep Utah moving! 

  • Additionally, the WB I-215 ramp to SB I-15 is in its final configuration with traffic merging onto I-15 separately from the EB I-215 traffic.
  • Motorists should be aware that construction will continue along I-15 throughout this year, but the new lane is available for use now, even as construction continues.

  • When the new southbound lane opened on I-15 earlier this month, a new traffic configuration was put in place at the I-215 interchange and the 7200 South off-ramp. Please remember to allow room and time for traffic to merge onto and off of I-15 as everyone adjusts to the new traffic pattern.

Project Overview

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.
