The California Highway Patrol and Caltrans are working together to reduce speeds on the Bay Bridge as the structure continues to undergo seismic retrofits, bridge officials said today.
Sensors built into the bridge have determined that westbound motorists typically drive about 10 mph over the speed limit during off-peak hours, according to bridge officials.
The CHP has therefore been increasing patrols on the span.
Officials said two temporary detours on the structure, which are products of the retrofit work, have made it especially important for motorists to obey speed limits on the bridge.
Another detour is scheduled to be put in place in early 2012. Increased CHP patrols will continue throughout August, officials said.
