Radar, hi-res cameras to check Richmond-San Rafael Bridge

News

(KRON) — Caltrans is about one-third of the way done repairing the Richmond-San Rafael Bridge’s crumbling expansion joints.

Ten of the 31 joints have been replaced after concrete has repeatedly fallen from the top deck of the bridge onto the lower deck, sometimes hitting moving vehicles and causing massive traffic delays.

Lane closures will continue overnight on the western end of the bridge as crews make those repairs. Drivers will also see more of those thin steel plates at the repair locations.

This week Caltrans will also use trucks with ground penatrating radar, hi-res video cameras to survey the condition of the bridge decks.
