I-15 Southbound - Weekly Construction Update

i15 new

Safety Tip

There have been a number of traffic shifts implemented throughout the construction zone. For your safety and that of construction crews, please be aware of lane restriping and signage as you are driving.

New Construction Activities

  • Drivers are advised to watch for a new traffic pattern at the 12300 S off ramp beginning Thursday, October 18th. Traffic will shift to the east to accommodate additional ramp construction.
  • Crews plan to close 4800 S between Commerce Drive and Riverside Drive Saturday, October 20 from 9 p.m. to 8 a.m., as crews begin bridge modifications. Please use the posted detour (see map below)
    • Additionally, a minimum of 5 nights following the closure, the crews will be placing bridge supports in this area. Residents and businesses may notice an increase in construction noise and vibrations while this work occurs.
  • Crews will continue working in the freeway median as they install foundations for overhead signs. Drivers can expect narrowed shoulders at all hours and nightly left lane closures on southbound and northbound lanes, for the next six to eight weeks. Please be aware and drive carefully.
  • Dominion Energy (Questar) has begun work on 7200 S. between 700 W. and just west of Bingham Junction Blvd. This work is anticipated to take 1 month and includes shoulder closures and possible sidewalk closures along the north side of the road between I-15 and Bingham Junction.

Ongoing Construction Activities

The following are ongoing activities along the Project corridor.
Please note that due to weather, Project conflicts, utility issues, or equipment/supply issues, schedules are subject to change.

  • Crews will continue work along the southern segment of the I-15 Southbound project - from I-215 to 12300 S. Work will include:
    • Demolition of existing barrier and concrete pavement
    • Roadway excavation and drainage work along the outside shoulder
    • Paving a new lane along the shoulder
    • Removal of existing pavement at specified on-ramps
  • The 7200 S. to southbound I-15 on-ramp is reduced from 2 lanes to 1 lane to accommodate ramp and wall construction for the new interchange configuration.
  • The point where traffic from I-215 merges from three lanes to two before entering southbound I-15 traffic has shifted north to allow for construction of the new interchange configuration. Previously, motorists merged left to right - now, motorists merge from right to left.

What to Expect

  • Drivers can expect nightly lane closures, including on and off ramps
  • Lane closures may occur on the following schedule:
    • Monday - Thursday, 9 p.m. - 5 a.m.
    • Friday, 11 p.m. - 6 a.m.
    • Saturday, 11 p.m. - 8 a.m.
    • Sunday, 6 p.m. - 5 a.m.
  • 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 still 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.

    Visit UDOT's Express Lane info page for more information on using the Express Lanes properly.

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.
