Document Description
Caltrans proposes to repair damaged and stolen electrical systems and power cables on the Richmond San Rafael Bridge on I-580 from PM 6.00 to 7.78 in Contra Costa County and PM 0.00 to 2.70 in Marin County. There has been about 1500 feet of wire stolen on the west side of the bridge from Piers 1 through 30 along the bicycle/pedestrian path. New aluminum wire will be installed, and wire theft prevention measures will be implemented. At piers 48 and 34, the conduit and wiring for the navigation and foghorn systems has corroded and will be replaced. Dedicated breakers will be installed for each system at pier 34 to ensure proper operation and compliance with safety standards (currently the wires are incorrectly landed on the same breaker). The work on the piers will be conducted from a boat and won’t require any climbing. The work at the piers will be completed in about a week. No in-water or under-water work is proposed at the piers. There are also several places along the bridge where the communication wiring has been cut or missing, so the wiring will be replaced or reconnected where needed. There have also been several acts of vandalism on the east end of the bridge that will need to be repaired. New power cable from the splice point to the termination box, new conduit to the house power cabling, new mounting strut to support the conduit, and vandal-resistance pull-boxes will be installed.
