Current Construction Status
S.R. 201 to 12300 South & 7200 South Widening
I-15 Southbound Weekly Construction
Heads up! For your safety and that of our construction crews, please watch for lane shifts starting at 9000 S. Please avoid distractions and drive safely through this project and it’s work zones.
New Construction Activities
- Drivers using eastbound 12300 S to get on I-15 SB will see a shift at the on-ramp. This is expected to continue in that configuration for approximately 10 days. Please watch for this new configuration and drive carefully in this area.
- Crews are working between 9000 S and 12300 S on roadway paving and permanent barrier installation marking progress toward completion of the southern segment of the project.
- Work to widen the 5900 S. and 4800 S. bridges to accommodate the additional southbound lane has been underway and is scheduled to continue for several weeks. Area residents and businesses may notice an increase in construction noise and vibrations while this work occurs, including overnight hours. This will include day and night-time flagging operations on both 5900 S. and 4800 S. to accommodate bridge construction.
- Over the next week, traffic on mainline I-15 between 9000 S. and 12300 S., along with associated entrance and exit ramps, will be shifted into their final traffic configuration. This work will be performed during off peak hours. Please watch for these new configurations.
- Traffic on the 7200 S. southbound entrance ramp will be shifted east to the new concrete pavement by mid-November to allow for the remainder of the ramp construction to be completed.
- Dominion Energy (Questar) is working** 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 northern and southern segments of the I-15 Southbound project – from 3300 S. 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
- Placing of permanent barrier along the shoulder
- 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 few weeks.
- 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. – 7:30 a.m.
- Saturday, 11 p.m. – 8:00 a.m.
- Sunday, 6 p.m. – 5 a.m.*
- *On Sunday, the right lane will be closed all day to accommodate crews.
- 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
