I-8 Eastbound Lane Closures Beginning May 14, 2023

El Centro, Calif. — All lanes of eastbound Interstate 8 (I-8) between Winterhaven/4th Avenue in Imperial, California and 16th Street in Yuma, Arizona will close Sunday, May 14 through Thursday, May 19 from 9 p.m. to 5 a.m. for the Colorado River Bridge Project. Motorists will detour by exiting towards Winterhaven/4th Avenue, turn right on to 4th Avenue and continue southbound towards 16th Street. Turn left onto U.S. 95/ 16th Street and continue heading eastbound towards the I-8 on-ramp.

Beginning Tuesday, May 16 and continuing through Tuesday, June 6, traffic on eastbound I-8 between Winterhaven and U.S. 95/16th Street will be reduced from two lanes to one. 

The closures are part of an ongoing project between Caltrans and the Arizona Department of Transportation to upgrade the I-8 Colorado River Bridge. The work includes resurfacing the bridge deck, replace bearings at bridge hinge locations, as well as replace approach slabs, defective guardrail, and seismic bearings. 

The construction work schedule is subject to change due to weather, traffic incidents, or other maintenance considerations. Travelers are reminded to watch for highway workers and moving equipment and to Be Work Zone Alert.
