Current Construction Status
S.R. 201 to 12300 South & 7200 South Widening
I-15 Southbound Weekly Construction
Tanker Fire Roadway Repair Impacts
Due to the tanker fire that occurred on Feb. 22, crews will be working on I-15 Southbound at 1800 S. to make repairs to the roadway.
- On March 27 and March 28, 2019, there will be nightly lane closures in place from 400 S to 1800 S to accommodate crews removing damaged barrier and concrete.
- Nightly lane closures will also be in place for the pavement repair operations on March 30.
I-15 Southbound New Construction Activities
- Yesterday, Thursday March 21, 2019, traffic shifted at the 7200 S on ramp to new pavement. Drivers please watch for the new traffic pattern.
- Beginning as early as Sunday March 24, 2019, traffic will be shifted east at the 5300 S off ramp to new pavement in preparation for an upcoming lane split. Drivers please watch for the new traffic pattern.
- In the area of 4800 S, crews will begin constructing retaining walls. Area residents and businesses may notice increased construction noise while this work occurs.
- Just north of 5900 S on I-15, crews are installing drainage. Area residents and businesses may notice increased construction noise while this work occurs.
Ongoing Construction Activities
Crews will continue work along the northern segments of the I-15 Southbound project – from 2700 S. to 7800 S. You can expect:
- Current work in the northern segment (2700 S. – 7800 S.) may include crews working at various locations on drainage, excavation, retaining walls, bridge widening, and utility relocation in preparation for the new lane addition.
- Between 2700 S. and 4500 S. crews are:
- Grading and constructing new retaining walls between 3600 S and 3900 S.
- Removing wall panels and barrier between 3500 S and 3800 S.
- Between 4500 S. and 5900 S. crews are:
- Grading and installing drainage at exit and entrance ramps.
- Grading and constructing new retaining walls between 4500 S and 4800 S.Installing soil nail wall below the Vine St. underpass
- Widening bridges at 5900 S. and 4800 S. Work in the area is scheduled to continue for the next several months and drivers can expect one-way flagging operations and lane closures.
- In the I-15/I-215 interchange area crews are:
- Constructing new retaining walls adjacent to the 7200 S. exit ramp and the other near the I-215 WB to SB ramp.
- Between I-215 and 7800 S. crews are:
- Installing drainage and grading at 7200 S exit ramp.
- Paving and barrier placement at the 7200 S. entrance ramp
While the new lane has been completed in this area, crews will continue work on other items along the southern segment of the I-15 Southbound project – from 9000 S. to 12300 S. You can expect:
- Placement of concrete slope paving at 9800 S. This will require a daytime one-way flagging operation on 300 W. Area residents and businesses may notice traffic delays on 300 W. and an increase in construction noise while this work occurs.
- Pothole repair at 10000 S.
- Installation of utilities from 9000 S. to 12300 S. This will result in nightly shoulder closures between 9000 S. to 12300 S.
Please note that due to weather, Project conflicts, utility issues, or equipment/supply issues, schedules are subject to change.
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. – 7:30 a.m.
- Saturday, 11 p.m. – 8:00 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.
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.
- Construction expected to span two construction seasons
