Bridge Delay for Rare Birds | San Francisco News

Though work on the bridge deck continues, sidewalk installation is on hold. With fewer than 6,000 of these secretive sparrows left in the Bay Area, officials are collaborating with biologists to safeguard nests while keeping the vital 1934 bridge on track—already 65% complete on structural repairs.
