Beginning early morning April 4, southbound I-15 from 200 South to 700 South in Clearfield will move to a crossover traffic configuration. One lane of traffic will cross onto the opposite side of the freeway, protected by a concrete barrier, and drive against traffic. This traffic configuration will allow crews to work in the median of I-15 and replace bridge structures. Speeds will be reduced to 60 mph through the crossover configuration.  

A northbound crossover from 800 North in Clearfield and 5600 South in Roy will follow in the weeks to come. The crossovers will be in the left lane for through traffic, so drivers needing to exit should stay right. There are no crossovers at 650 North to provide access to Hill Air Force Base.  

700 South (Clearfield)

The southbound I-15 off-ramp at 700 South in Clearfield will close as early as 10 p.m. on Tuesday, April 7 to 5 a.m. on Wednesday, April 8 as crews remove barrier in the area. Drivers can detour to Antelope Drive to exit southbound I-15.  

200 South (Clearfield)

Traffic in and out of the Airlane Drive neighborhood at 200 South will utilize a one-way automated flagger device. This configuration will remain in place through December 2020.   

650 North (Clearfield)

The westbound 650 North on-ramp to southbound I-15 will close nightly from 10 p.m. to 5 a.m. beginning Saturday, Feb. 8 for up to two months for bridge construction. Drivers can detour to Main Street and 700 South in Clearfield for access to southbound I-15. Click here for a detailed route map.

Drivers at 650 North and I-15 in Clearfield will see lanes shifted to a new traffic configuration. This work will allow crews to perform structural work on the south side of the I-15 bridge at this location. Lanes will remain shifted in the new traffic configuration for up to six months. A current map of the new traffic pattern can be found here. Drivers should stay alert and use caution while navigating this new configuration.  

Construction schedules are weather-dependent and subject to change.
