Southbound I-15 On-ramp at Riverdale Road

The southbound I-15 on-ramp at Riverdale Road will close as early as 10 p.m. on Sunday, Sept. 27, to 5 a.m. on Monday, Sept. 28, for shoulder removal. Drivers can detour to 5600 South in Roy to enter southbound I-15.  

200 South (Clearfield)

Crews are reconstructing the bridge at I-15 and 200 South in Clearfield. To accommodate this work, traffic in and out of the Airlane Drive neighborhood at 200 South is utilizing a one-way automated flagger device. This configuration will remain in place through December 2020.  


Southbound I-15 from 200 South to 700 South in Clearfield is now in a crossover traffic configuration. A northbound crossover from 800 North in Clearfield and 5600 South in Roy has also been implemented.


One lane of traffic crosses onto the opposite side of the freeway, protected by a concrete barrier, and drives against traffic. Both 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.


The traffic configurations are allowing crews to work in the median of I-15 to replace and widen bridge structures. Speeds are reduced to 60 mph through the crossover areas.  

650 North (Clearfield)

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.
