Express Lanes

The Interstate 15 Express Lanes system in March 2018.

LAYTON — The state says preliminary work on their Northern Utah Interstate 15 construction project is finished and they’re ready to start the heavy lifting — which means parts of the freeway will be closed soon.

Utah Department of Transportation spokesman Vic Saunders said the I-15 Davis-Weber Express Lanes project will start as early as Monday, May 6. Saunders said initial work will begin overnight, mainly on northbound I-15 from Hill Field Road to Antelope Drive, as crews widen the roadway shoulder in that area.

Motorists should expect reduced lanes from 7 p.m. to 6 a.m. Monday through Friday and again from 7 p.m. to 9 a.m. on Saturdays. Commuters should also expect Sunday daytime and nighttime lane closures, Saunders said.

The $169 million project will add lanes to north and southbound I-15 between Hill Field Road and Interstate 84 near the Riverdale/Ogden border, expanding the state’s Express Lanes system that allows carpoolers, buses, motorcycles, emergency vehicles and clean-fuel vehicles.

The system also allows solo drivers in the lane when space is open, but those motorists have to pay a fee for usage. An electronic payment process charges solo drivers by using an algorithm that adjusts the price based on current traffic conditions. Costs are higher when I-15 is more congested.

As part of the project, UDOT will also replace freeway bridges at Church Street in Layton and at 200 South in Clearfield, as part of the project. They will replace bridge decks at Gentile Street in Layton, at 700 South and 650 North in Clearfield, and at 5600 West and the Union Pacific Railroad tracks in Roy.

Gentile Street may be closed for as many as 45 days, with Church Street closed for up to six months. The two Layton streets would not be closed simultaneously.

UDOT spokesman John Gleason said the project isn’t scheduled to be complete until 2020. Once the project is done, the Express Lanes system will extend 80 miles, running continuously from Utah County to Weber County. Gleason said the completed project will make UDOT’s Express Lane the longest uninterrupted system in the United States.

The I-15 reconstruction is one of 169 construction projects statewide that are currently in progress or scheduled to start this year, a list totaling $2.1 billion, Gleason said.
