Construction Update – Week of May 25

In observance of Memorial Day, no closures are scheduled from Friday, May 22, through Monday, May 25.

We hope you enjoy the holiday weekend and please drive safely!

Pavement grinding on I-15, between Magnolia Ave. and State Route 60, is scheduled during the weekdays and weeknights. The grinding of existing and temporary lanes are necessary for operational and safety reasons, as well as future noise reduction of motorists using the I-15 and 15 Express Lanes.

This activity will create noise, due to equipment movement, back-up alarms, and related construction activity. We apologize for any inconvenience this may cause.


A full closure of the northbound 15 at Magnolia Ave. including the 15 Express Lane connectors, is tentatively scheduled June 1,2, and 3, from 10 p.m. to 4 a.m.

A full closure of southbound 15 at Hidden Valley Pkwy. is tentatively scheudled June 4, 5, and 8, from 11 p.m to 5 a.m.

More information, including detours, will be provided next week.
