Wasatch Constructors will close most of northbound I-15 through the reconstruction corridor Tuesday and Wednesday nights.

The I-15 reconstruction contractor on Monday added a freeway closure for Tuesday and Wednesday that, when combined with other work already planned, will result in the shutdown of northbound I-15 from 9000 South to 1000 North.That closure will begin at 10 p.m. Tuesday and end at 6 a.m. Wednesday, then repeat during the same hours Wednesday night and Thursday morning.

A segment of southbound I-15 - from 1000 North to 500 South - also will be closed at the same time both nights.

Freeway closures also are planned for Thursday and Friday nights. For the latest construction schedule updates, call 1-888-INFO-I15 or check the contractor's Web site at (www.I-15.com).
