Caltrans says you can expect lane closures on Interstate 8 on the Colorado River Bridge.

The daytime closures are part of an ongoing project between Caltrans and the Arizona Department of Transportation to upgrade the bridge. A westbound lane will be closed Monday through Friday from 7 a.m. to 6 p.m. for the bridge work. The project will see resurfacing of the bridge deck, replace bearings at bridge hinge locations, as well as replace approach slabs, defective guardrail, and seismic bearings.
