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 final work on structures, grading, and other misc. items located outside the travel lanes, with nightly lane closures to accommodate final work.
Additional Lane Closures on I-15 and 7200 South:
- With decreased traffic volumes on I-15 and 7200 South, UDOT has given the contractor permission to close additional lanes on I-15 and 7200 South. These additional closures will allow the contractor to work more efficiently without impacting motorists.
- 7200 South
- Eastbound: Crews may restrict travel to one lane any time of day, as needed.
- Westbound: Crews may restrict travel to one lane from 8 pm to 10 am. On Sundays, they may restrict travel to one lane any time of day, as needed.
- I-15 Southbound
- Crews may begin closing an additional lane at 7:30 pm on any day of the week.
- 7200 South
- Beginning Sunday, eastbound traffic on 7200 South will be shifted to the north to accommodate roadway widening on the south side of the road.
- On Sunday, crews will be completing work on bridge structures near 3500 South. This may require additional right lane closures on 3300 South on-ramp and on mainline I-15.
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.
Visit UDOT’s Express Lane info page for more information on using the Express Lanes properly.
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.
