Construction crews will be working on the Interstate 8 Colorado River Bridge near Yuma.

The work will mean the eastbound and westbound lanes on the bridge will be closed. The work is scheduled for Friday from 7 a.m. to 6 p.m. and Monday and Tuesday again from 7 a.m. to 6 p.m. Additionally, the eastbound I-8 4th Avenue on-ramp will be closed those days from 7 a.m. to 6 p.m.

The work is part of an ongoing project between Caltrans and the Arizona Department of Transportation (ADOT) 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.
