SAN FRANCISCO (AP) — The $1.1 billion project to replace San Francisco's dangerous approach to the Golden Gate Bridge could face another delay, as leaders scramble to line up funding. The first phase is nearing completion on Doyle Drive, the approach originally built in 1937 that sits on unstable soil and lacks a median or shoulders. Crews have been working since 2009 to build a new highway interchange, viaduct and tunnel for the 1.6-mile road that's been newly dubbed Presidio Parkway.
