Crews are now well into Phase II of the Presidio Parkway Project, which began in late 2009 and will convert Doyle Drive into a lush parkway that will serve as the San Francisco approach to the Golden Gate Bridge by late 2016. The 1.6-mile segment of Route 101 extends from Broderick Street to the Golden Gate Bridge toll plaza.
