Starting Wednesday, an offramp that connects motorists from Park Presidio Boulevard to Doyle Drive will be shut down for three years, the second long-term street closure in a month involving the $1.1 billion project to rebuild the southern approach to the Golden Gate Bridge.
The offramp, which connects northbound motorists from Park Presidio Boulevard (also state Highway 1) to southbound Doyle Drive (U.S. Highway 101), will close Wednesday and not reopen until 2013.
Since Jan. 10, an offramp connecting northbound Doyle Drive to southbound Park Presidio Boulevard has been closed.
Nearly 120,000 vehicles use the 74-year-old highway daily. The rebuild project is expected to be complete by 2014.
When finished, the aging southern approach to the Golden Gate Bridge will be transformed into a state-of-the-art freeway to be called Presidio Parkway.
Doyle Drive, which has been in existence since 1936, will be completely demolished. It has been deemed structurally and seismically unsafe.
As early as 1955, the state recommended reconstructing Doyle Drive to handle increased congestion.
The roadway is named after Frank P. Doyle, a director of the California State AutomobileAssociation.
