I-8 Construction to Close All Eastbound Lanes of Colorado River Bridge

El Centro, Calif. — Construction crews will close all eastbound lanes of Interstate 8 (I-8) on the Colorado River Bridge near Yuma, AZ, on Wednesday, April 19th from 9 p.m. to 5 a.m. for replacement of seismic bearings, according to Caltrans. Additionally, the 4th Avenue on-ramp to eastbound I-8 will be closed from 9 p.m. to 5 a.m.

Motorists will detour by exiting towards Winterhaven/4th Avenue. Turn right on to 4th avenue and continue southbound towards 16th street. Turn left onto W.16th/U.S 95 street and continue heading eastbound towards I-8 on-ramp.

The daytime 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.
