S.R. 201 to 12300 South & 7200 South Widening

Ongoing Construction Activities

Crews will continue work along the northern segments of the I-15 Southbound project, from 2700 South to 7800 South. Please expect:

Work between 2700 South and 5900 South
  • Crews are striping and shifting lanes into their permanent configuration.
Work in the I-15/I-215 interchange area:
  • Crews will continue work on bridges, including erecting bridge supports and paving the bridge decks.
7200 South between 700 West to Bingham Junction:
  • Crews will be closing one eastbound lane on 7200 South between 9 am and 3 pm. This will accommodate the UPRR bridge work and pile driving activities. This closure is expected to be intermittent through the end of the project.
  • Drivers can expect shoulder closures between Bingham Junction and I-15 as well as nightly lane closures.

Please note that due to weather, Project conflicts, utility issues, or equipment/supply issues, schedules are subject to change.

What to Expect

I-15 lane closures may occur during the following times:

  • Monday – Thursday, 9 p.m. – 5 a.m.
  • Friday, 11 p.m. – 7:30 a.m.
  • Saturday, 11 p.m. – 8:00 a.m.
  • Sunday, 6 p.m. – 5 a.m.
  • Drivers can expect nightly lane closures, including entrance and exit ramps.
  • Drivers can expect temporary barriers and the outside shoulder to be closed. Use inside shoulder or signed pullouts in case of emergency.
  • Residents and businesses adjacent to active construction can expect some increase in noise and dust.

HOV Suspension Reminder

HOV/Express Lanes are suspended through the I-15 Southbound project from S.R. 201 to 12300 S. These suspensions will be in place for the duration of the project.

Solo drivers may use the HOV lane as a general-purpose lane as crews work to keep traffic flowing but should note the following:

  • Don’t cross the double white lines–it’s unsafe and illegal.
  • Don’t weave in and out–enter and exit at designated areas indicated by white-dotted lines.
  • Trailers and vehicles with a gross vehicle weight of more than 12,000 pounds are not allowed in the two left lanes.

Other Projects

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. 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.


The I-15 Southbound project will use $180 million dollars in state funds, which accounts for the environmental study, design and construction.
