Current Construction Status
S.R. 201 to 12300 South & 7200 South Widening
I-15 Southbound Weekly Construction
New Construction Activities
- Crews are working to widen the bridge structures above Winchester St. and the UTA tracks at approximately 6600 South and I-15 in Murray. Crews will use cranes recently brought into the area to perform this work. Area residents will notice increased construction noise and vibration. Residents can also expect intermittent night time work through the construction season. Drivers can expect one-way flagging operations and lane closures.
Ongoing Construction Activities
Crews will continue work along the northern segments of the I-15 Southbound project – from 2700 S. to 7800 S. Please expect:
- Work on the median overhead signs between 3300 South to 7200 South. Crews will close the left lane on north and southbound I-15 for the coming months to accommodate this work.
- Crews will continue road excavation and grading operations between 2700 South and 4500 South.
- Crews are working to allow for the lane addition at the 3300 South off-ramp. In its final configuration there will be an additional left turn lane at the bottom of the ramp from southbound I-15 to eastbound 3300 South.
- Work between 2700 South and 5900 South:
- Crews will continue road excavation and grading operations.
- Crews will continue building new retaining walls between 4500 South and 4800 South.
- Near 4800 South and 3600 South, crews are installing wall panels for the next few weeks.
- At 5900 South and 4800 South, crews will continue work to widen these bridges. Drivers can expect one-way flagging operations and lane closures beneath I-15 on these two roads.
- Work in the I-15/I-215 interchange and 7200 South area:
- Near the I-215 to I-15 ramp, crews will be removing and excavating pavement.
- As crews work to widen the bridge structures above Winchester St. and the UTA tracks at approximately 6600 South and I-15 in Murray, area residents will notice increased construction noise. Residents can expect intermittent night time work through the construction season. Drivers can expect one-way flagging operations and lane closures.
- The westbound I-215 loop ramp split remains in place. Both sides of the split provide access to I-15 and 7200 S.
- Pedestrians are advised to observe sidewalk closures in the area and to only cross at signal crossings at 300 West or 700 West. The north sidewalk on 7200 South is currently closed and pedestrian traffic has been directed to the south sidewalk.
- Along 7200 South crews will be conducting utility work ahead of the roadway construction.
- Westbound 7200 South is restricted to two lanes between I-15 and 700 West. A shorter segment of eastbound 7200 South is restricted as crews work on the Utah Transit Authority (UTA) Bridge. All movements are open at the intersection of 700 West and 7200 South. This traffic pattern is anticipated to be in place through September as crews widen the bridge structure over 7200 South. Expect delay and plan ahead.
While the new lane has been completed south of 7800 South, crews will continue work on other items along the southern segment of the I-15 Southbound project, from 9000 South to 12300 South. Please expect:
- Continued utility installation from 9000 South to 12300 South. Crews may close shoulders or lanes overnight to accommodate this work.
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
