Construction FAQ

What is the construction schedule? What is the schedule for Phase II construction?

Preconstruction activities began in summer 2009 and included native plant and seed gathering, tree removal and utility relocation. Major construction began in December 2009, while construction of the northbound High Viaduct, the northbound Battery Tunnel and the Main Post Tunnels began in summer 2012. Traffic was shifted to the final roadway in July 2015 after a weekend closure. Site restoration and landscaping is now underway.

View the construction schedule.

What are the hours of construction?

  • 7:00 a.m. - 7:00 p.m. (Mon.-Fri.)
  • 9:00 a.m. - 6:00 p.m. (Sat.)
  • Occasional Sunday work
  • Night work as needed
  • Potential extended hours to expedite construction, as needed

Why is the speed limit 35 mph on Doyle Drive?

While Doyle Drive is still an active construction site, the speed limit is 35 mph to ensure the safety of road workers and the general public. When the project is complete, the speed limit will change to 45 mph to match the speed limit on the Golden Gate Bridge.

What efforts are being made to mitigate dust?

Dust suppression measures are in place, including watering stockpiles up to three times daily, or as necessary, and application of tackifier, a compound that increases the stickiness of the pile surface and minimizes dust.

Why are no soundwalls planned along the project corridor during construction?

The project team studied noise barriers near residences along Storey Avenue, Armistead Road, Officer Family Housing and Lyon Street, and published its findings in the FEIS/R. The study concluded that a noise barrier at all but one location was infeasible according to Caltrans protocol. A soundwall would be feasible at Armistead Road, but it was determined such a soundwall would be inconsistent with the natural and cultural landscape and its benefits would not outweigh its negative effects.

What will happen to the Pet Cemetery during construction?

The Pet Cemetery was designated an environmentally sensitive area and was fenced off and protected during construction. The Swords to Plowshares organization has initiated a volunteer program to maintain the cemetery in partnership with the Presidio Trust. Later in the year, the girders that protected the Pet Cemetery during construction will be removed, and access to the Pet Cemetery will be restored.

Why is tree removal necessary?

The area surrounding the construction site had to be carefully cleared of trees to create space for construction equipment and materials. Although there is a visual impact as a result of the tree removal, an extensive landscaping effort is a critical part of the project design. The project’s Tree Removal and Protection Plan was carefully developed in collaboration with experts and the Presidio Trust to remove only the trees necessary and protect the surrounding area. Furthermore, the eventual replacement of existing trees with young, healthy and more diverse trees will help improve this man-made forest in the long term.

View the tree removal and protection plan fact sheet.

What is the plan for replanting and landscaping after construction is complete?

Native plants and seeds were collected prior to tree removal and construction. Those plants and seeds are being grown in the Presidio Nursery and will be reused in the post-construction landscaping plan and wetlands mitigation.

Will there be any impacts to Marin commuters?

Traffic to and from the Golden Gate Bridge and 19th Ave/Hwy 1 will remain flowing throughout construction. This corridor is a construction zone with continually changing conditions, so delays may occur. However, the connections between 19th Ave and the Golden Gate Bridge will remain open.

Temporary ramp and lane closures will be required due to construction. These closures are generally scheduled to occur overnight, and advance notice will be provided.

Which local roads will be closed during construction?

  • Lincoln Boulevard between McDowell Avenue and Montgomery Street (June 2, 2010-April 10, 2012) 
  • Halleck Street (April 21, 2012-2016)
  • Marshall Street (Permanently beginning April 21, 2012)
  • Slip Ramp (Permanently beginning April 27, 2012)

Will there be any additional closures of Doyle Drive during construction?

There were two planned weekend closures, one in 2012 and one in 2015. The first weekend closure occurred on April 27-30, 2012, to switch traffic onto the temporary bypass and achieve seismic safety. The second weekend closure occurred on July 9-12, 2015, to transfer traffic onto the final roadway. No additional full closures are anticipated.

General Project FAQ

Why is the Presidio Parkway design the best design for the corridor?

The Presidio Parkway has the unique features of a parkway design, including a wide landscaped median, a traffic calming transition to city streets, and reduced lane and shoulder widths, with enhanced pedestrian connections within the Presidio to the Main Post, Crissy Marsh, the National Cemetery and Historic Batteries. It provides new direct access to the Presidio and enhanced views from within the Presidio. It will be a spectacular regional gateway that complements the unique environment of San Francisco and the Presidio, a national park. View the overview booklet for more information about the parkway's design and features.

Why was replacing Doyle Drive so important to the region?

Replacing Doyle Drive with a modern, earthquake-safe facility is a high-priority safety project. Doyle Drive is the primary highway and transit linkage through San Francisco between counties to the north and south, yet requires extensive seismic, structural and traffic safety upgrades. Should an earthquake or structural failure force the closure of Doyle Drive for any significant length of time, freeways in the North and East Bay areas would experience staggering congestion from rerouted trips, and the regional transit and ferry systems would be greatly overburdened. Severe economic hardship and job relocation would likely result for the North Bay counties as well as San Francisco. In the short term, regular maintenance, seismic retrofits and rehabilitation activities are keeping the structure safe. However, in the long term, permanent improvements are needed to bring Doyle Drive up to current design and safety standards.

How does the project design improve connectivity in the Presidio?

Doyle Drive is located within a National Historic Landmark District and a national park and, as such, the design team went to great lengths to reduce the footprint of the new roadway, connect the Presidio to the surrounding area, and respect the project setting. The parkway concept replaces the old Doyle Drive with a new roadway designed as an integrated part of the national park, rather than just a highway running through it. The addition of tunnels to the design also helps increase green space within the park and improve connections between points north and south of the roadway. These concepts are described in more detail in the Connecting People and the Park fact sheet.

How does the new roadway serve bicyclists and pedestrians?

The new roadway design will allow pedestrians and bicyclists to cross over or under Doyle Drive at numerous locations in accordance with the Presidio Trails and Bikeways Master Plan, including at Lincoln Boulevard, McDowell Avenue, Halleck Street, Girard Road, Richardson Avenue and adjacent to Tennessee Hollow. In addition, the design will provide enhanced opportunities for crossing Doyle Drive and new connections to Battery Blaney, Main Post and Crissy Field in the areas over both sets of tunnels.

How will the project be funded?

A balanced funding strategy has been developed for Doyle Drive, relying on a combination of federal, state, regional and local funds to meet the project's approximately $1.045 billion price tag. Visit the Costs & Funding page for more information.

Does the Presidio Parkway increase traffic by accommodating more vehicles?

The Presidio Parkway design will serve the same traffic capacity as Doyle Drive does now. In response to public comments, the project's traffic study was expanded beyond its original parameters. The results of the expanded analysis are presented in the FEIS/R. No adverse impacts from this project onto the surrounding neighborhoods were indicated. The study found that roadway intersections and highway segments will have the same general level of congestion as forecasts show for the roadway if no changes were made.

How many lanes of traffic does Doyle Drive carry in the final condition?

In the final condition, northbound and southbound traffic will travel on separated roadways. Northbound traffic will have 3 lanes. Southbound traffic will have 3 lanes, with the addition of an auxiliary lane (an outside lane to facilitate merging) to carry traffic from northbound Highway 1 to southbound Highway 101 and to the new Marina/Presidio exit. See the Corridor Overview image for a simulation of the final condition:

Average lane width will increase to 11', with an outside lane of width 12' to accommodate buses. In addition, both northbound and southbound roadways will have 10’ outside safety shoulders for emergency and disabled vehicles.


Does Doyle Drive have a new name now that major construction is complete?

There is currently no effort to rename the roadway. Upon completion, the new roadway will maintain its historic name, Doyle Drive, named for Frank Doyle, the North Bay banker who advocated for the construction and financing of the Golden Gate Bridge 75 years ago.

Does the Presidio Parkway design affect the YMCA pool?

The Presidio Parkway does not change Building 1151 (YMCA pool) and so the building will remain intact.

What is the footprint of the project?

The total roadway width will be 105.3 feet and the overall facility width, including the landscaped median, will vary from 121.7 feet to 146.3 feet. The new facility will overlap a large portion of the existing facility's footprint east of the Park Presidio Interchange.

How does the Presidio Parkway design affect the traffic between Richardson Avenue, the Marina, and Girard Road?

The design achieves a traffic flow between Marina Boulevard and Richardson Avenue that is very similar to prior conditions. Also, some traffic in the area has been alleviated by the introduction of Girard Road access into the Presidio, which attracts local traffic to and from currently unavailable destinations within the Presidio and points south.

Traffic models of the new configuration for this interchange show no increase in traffic delays for those traveling from the Marina to Doyle Drive, or along Doyle Drive to Richardson Avenue or Girard Road.

View a video of the new configuration.

What is a P3 and why was it chosen for this project?

A public-private partnership is a government service that is funded and operated through a partnership of the government and one or more private sector companies. In order to achieve greater schedule and budget certainty and to provide the expected level of operations and maintenance service for this new facility, Phase II is being delivered through the state's first public-private partnership (P3) under the authority of Senate Bill X2 4. The developer, Golden Link Concessionaire, was selected to design, build, finance, operate and maintain the project for 30 years while Caltrans and SFCTA maintain an oversight role. This P3 method of delivery was selected to reduce costs, free up state funding for other uses, transfer cost-overrun risks to the private developer and ensure a high maintenance standard during the 30 year contract.
