Crews will be repairing striping along the project length from Layton Parkway to Riverdale Road on I-15, both north- and southbound directions, on Friday, Dec. 6 between 10 a.m. to 2 p.m. and again between 10 p.m. and 5 a.m. Crews will stripe the lane shoulders between 10 a.m. and 2 p.m. and will use a rolling slowdown to perform this work. Inside lanes will be striped at night between 10 p.m. and 5 a.m. Lane restrictions will be in place during this time frame. Drivers should expect delays and use caution through the work zone. 

In preparation for traffic shifts at 700 South, crews will be striping lanes under I-15 on Friday, Dec. 6, between 9 a.m. and 3 p.m. This work requires single lane closures in both east- and westbound directions. Following the lane striping work, traffic at 700 South will remain shifted for up to two months as crews construct bridge structures at that location.

Lanes at 650 North and I-15 in Clearfield have been shifted and reduced. Westbound lanes have been reduced to two through lanes under I-15. Eastbound lanes have been reduced to one left-turn lane and one lane for through traffic. 

The north sidewalk under I-15 at 700 South (S.R. 193) will close as early as December 6 for bridge reconstruction through February 2020. Pedestrians and cyclists should detour to the crosswalks east or west of the closure. Click here for a detailed detour flyer.

Construction work is now in full swing along the length of the project. Drivers should expect shifted lanes on I-15 throughout the project limits. Nightly lane restrictions are still in place from 7 p.m. to 6 a.m. Monday through Friday and from 7 p.m. to 9 a.m. on Saturdays. Lane restrictions will be in place during the day and night on Sundays.
