What Work Is Being Done

Crews will install new pavement striping and make additional roadway improvements along I-10 between mile markers 117.4 and 126.7. Officials say the upgrades are aimed at improving safety and visibility for drivers traveling through the corridor.

When Lane Closures Will Happen

Construction is scheduled to take place Monday through Saturday from 8 p.m. to 5 a.m., depending on weather conditions.

What Drivers Should Expect

Drivers should expect intermittent lane closures in both directions during those overnight hours, which could lead to delays. DOTD is urging motorists to plan ahead and use caution when traveling through the area.
