Current Construction Status
S.R. 201 to 12300 South & 7200 South Widening
I-15 Southbound Weekly Construction
Heads up! Please avoid distractions and drive safely through this project and it’s work zones. For your safety and that of our construction crews, please watch for new traffic patterns, lane shifts and construction 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 Saturday, Oct. 20th. Traffic will shift to the east to accommodate additional ramp construction.
- A full closure of 4800 S between Commerce Drive and Riverside Drive is scheduled for Saturday, Oct. 20 from 9 p.m. to 8 a.m., as crews begin bridge modifications. Please use alternate routes or follow posted detour routes (See map below).
- Work on the 4800 S. bridge will continue for several weeks. Area residents and businesses may notice an increase in construction noise and vibrations while this work occurs, including overnight hours.
- Crews will continue working in the freeway median to install foundations for overhead signs. Drivers can expect narrowed shoulders at all hours and nightly left lane closures on both southbound and northbound lanes, for the next six to eight weeks.
- 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. **This work is not associated with the I-15 Southbound project but is occurring in the project area.
Please note that due to weather, Project conflicts, utility issues, or equipment/supply issues, schedules are subject to change.
Ongoing Construction Activities
The following are ongoing activities along the Project corridor.
Crews will continue work along the norther and southern segments of the I-15 Southbound project – from 4800 S. to 12300 S. Work will include:
- 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
- Ongoing lane restrictions on 5900 S. with a night-time flagging operation to accommodate bridge construction.
- 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
