The I-15 reconstruction contractor will close both sides of I-15 Thursday night.

Wasatch Constructors also closed the freeway Wednesday night after adding the work to its weekly schedule Wednesday afternoon.Northbound I-15 will be closed between 4500 South and 2100 South, 10 p.m. Thursday until 6 a.m. Friday. Southbound I-15 will be closed from I-80 East to 3300 South at the same time.

Another added project will close 6400 South between 300 West and 700 West on Thursday and Friday, 8 a.m. to 5 p.m.

Also, Wasatch has decided not to close U-201 Thursday night but will do so on Friday as previously planned.

It had intended to close eastbound U-201 between Redwood Road and 300 West, and westbound U-201 between 300 West and 900 West, every weeknight this week.

But the contractor said Wednesday it had postponed all of those work shifts, except for Friday night's closure - from 9 p.m. until 6 a.m. Saturday. The southbound I-15 offramp to 2100 South will be closed during the same nine-hour period Friday and Saturday.
