Traffic Alert

Full Interstate 15 (I-15) ramp closures on State Route 126 (SR-126) are planned for Sept. 14 and Sept. 28, from 10 p.m. to 12 a.m. Through mid-September, we will continue reducing SR-126 to a single lane, alternating one-way on weekdays, from 7 a.m. to 7 p.m., as part of the SR-126 Paving project. This lane closure is needed to accommodate road paving activities. The location of the closure will vary as paving activities progress. 

Overview

We are repaving eight miles of State Route 126 between State Route 39 (1200 South) and U.S. Route 89 from Marriott-Slaterville to South Willard, Utah. The project is helping improve the pavement conditions, extend the life of the road, and enhance the driving experience for all users. Additional work includes restriping access ramps, bridge repairs, and replacing outdated signs along the corridor.
