Current Construction Status
S.R. 201 to 12300 South & 7200 South Widening
I-15 Southbound Weekly Construction
New Construction Activities
- Drivers are advised to watch for a new traffic pattern at the 7200 S offramp beginning September 23. Traffic will be temporarily shifted in this area to allow crews to safely work on improvements to the offramp. Please drive slowly and obey all posted signs.
- A full closure of 5900 S. between Sanford Drive and Stratler Street has been rescheduled to occur on the night of September 22 from 9 p.m. to 8 a.m. as crews begin bridge modifications. For your convenience, please see detour map below
- Additionally, for the 4-5 nights following the closure, 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.
- Beginning late September to early October and continuing through November, Dominion Energy (Questar) will begin work on 7200 S. between 700 W. and Bingham Junction Blvd. This work will include shoulder closures and possible sidewalk closures along the north side of the road between I-15 and Bingham Junction.
- Crews will be working in the freeway median as they install foundations for overhead signs. Drivers can expect narrowed shoulders and nightly left lane closures on southbound and northbound lanes. Please be aware and drive carefully.
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 to 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 of 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 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.
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.
- Construction expected to span two construction seasons
