For Immediate Release
Doyle Drive Will be Closed for a Weekend, April 27-30
SAN FRANCISCO - Doyle Drive will be closed for one weekend, April 27-30, from 8 p.m. Friday night to 5 a.m. Monday morning.
A historic event is on the horizon - Doyle Drive is coming down! The roadway that has linked the Golden Gate Bridge to San Francisco for 75 years is being replaced by a new state-of the-art roadway, the Presidio Parkway. During the weekend closure, crews will begin demolishing the aging roadway and transfer traffic onto a new, seismically safe bypass, comprised of the completed southbound tunnel and bridge and a temporary roadway. The weekend closure date could change due to weather.
During the weekend closure, motorists are asked to avoid the project area, use alternate modes of transportation, or travel by alternate routes, including the San Francisco - Oakland Bay Bridge and the Richmond - San Rafael Bridge. Expect major delays on the Golden Gate Bridge.
Moving traffic permanently off Doyle Drive and onto the new temporary bypass will establish seismic safety for the corridor, a major goal for the first phase of construction in the $1 billion roadway redesign. The first phase included construction of the Ruckman Bridge on Highway 1, the southbound High Viaduct, the first of four new tunnels and a temporary bypass. "Completion of Phase I construction means that drivers will travel on a new, safer roadway and makes room for the rest of the project to be built," said Dave Pang, Caltrans Construction Manager.
Phase II of construction will include construction of the northbound High Viaduct, the three remaining tunnels, and new connections to the Presidio. This phase will also include final landscaping.
"Seismic safety is very important for this heavily traveled corridor," said Bijan Sartipi, Caltrans District 4 Director. "We're very proud of the work that has been complete, and happy to see the project move into the second phase."
"The project is of great regional significance and will transform the Presidio, one of the treasures of San Francisco," stated José Luis Moscovich, Executive Director of the San Francisco County Transportation Authority. "It is truly exciting to achieve this milestone and get one step closer to the final product."
Weekend Activity Details
During the closure weekend, crews will use a fleet of 40 demolition hammers, now in transit from sites around the country. The machinery ranges in vertical reach from 30 to 56 feet, relying on hydraulic mechanisms to crush, hammer and chip away the old bridge.
Demolition over the weekend will occur around the clock and will focus on 'conflict points,' areas of Doyle Drive where the old roadway lies in conflict with the new bypass. This will allow crews to connect the bypass to the new permanent tunnel and bridge. After the corridor reopens on Monday morning in the new alignment, crews will turn their attention to the demolition of Doyle Drive's remaining segments, which is expected to take several months.

During the closure, motorists are asked to avoid the area and travel by alternate routes or modes of transportation.
Vehicles: Northbound traffic should use I-80/San Francisco - Oakland Bay Bridge to I-580/Richmond - San Rafael Bridge. Southbound traffic should I-580 to I-80 to I-280 towards the San Francisco Peninsula. Highway 1/Park Presidio Boulevard to and from the Golden Gate Bridge will remain open, however, motorists are asked to avoid this route as it will be heavily congested.
Buses: MUNI routes and Golden Gate Transit routes will be modified near the corridor. See www.sfmta.com and www.goldengate.org for more information.
Ferries: Ferry service between the San Francisco, Sausalito and Larkspur terminals will be increased.

Driving Condition After the Closure
Beginning Monday, April 30 after the roadway reopens, motorists will travel on the completed bridge and tunnel and a temporary bypass roadway. The temporary driving condition will have five lanes managed by a moveable median barrier to accommodate shifts in traffic demand. Expect delays as motorists adjust to the new driving experience.
The temporary bypass will meet today's seismic standards and prevent head-on collisions with the addition of a median barrier, improving the safety of the corridor while the rest of the project is built.
Media tours will be scheduled for the weeks of April 16 and April 23. Date and time for the tours will be based on construction activity. Invitations with additional details will be distributed soon.
