What to Expect
This project will involve a full closure of the westbound I-10 on-ramp from SR 80 (4th St), and traffic will be detoured to the eastbound on-ramp towards the next exit at Ocotillo Avenue. I-10 westbound will be limited to a single lane intermittently and only overnight from 8 p.m. to 6 a.m. Monday through Friday as crews perform work. ADOT will provide advance notice of restrictions and closures to email subscribers and on the project traffic alert web pages.
