The northbound I-15 offramp to eastbound 500 South in Bountiful will close for three weeks beginning Monday.

The adjacent loop ramp to westbound 500 South will close May 1, also for three weeks.

The closures are part of the ongoing effort to widen I-15 in southern Davis County, between I-215 in North Salt Lake and U.S. 89 in Farmington.

Both ramps were originally scheduled to close May 19, but the Utah Department of Transportation and its contractor adjusted the schedule to minimize impacts on traffic and nearby businesses and residential areas.

Motorists are advised to use 2600 South in Woods Cross or 400 North in Bountiful as alternate exits.
