About the Projects
Presidio Tunnel Tops
Through Fall 2021
In late 2019 we broke ground on the Presidio Tunnel Tops, 14-acres of new national parkland that will bridge over the Presidio Parkway tunnels, reconnecting the historic Main Post to the Crissy Field waterfront. Over two years, we will construct connecting pathways, scenic overlooks, meadows and gardens, picnic areas, a campfire circle, a renovated Crissy Field Center and an expanded Youth Campus. The site is scheduled to open in fall 2021. Visit
PresidioTunnelTops.org for details and updates.
December 2019 through Fall 2020
We’re expanding Crissy Marsh by seven acres just east of Halleck Street. This is the latest step in the 20-year restoration of Tennessee Hollow, the park’s largest watershed. To expand the marsh, we’ll remove landfill and install culverts beneath Mason Street. A section of Mason Street will be closed from the Mason Street warehouse parking lot to Halleck Street (see map) from December 2019 through Summer 2020, with a vehicular detour along Halleck Street. The in/out driveway to East Beach remains open. Alternative routes are available for bikes and pedestrians. We’ll plant thousands of salt marsh and riparian plants in Fall 2020.
Beautification of Girard Entry Corridor
December 2019 through Spring 2020
We’re beautifying the Presidio’s entrance along Girard Road from the Presidio Parkway / Highway 101 interchange to Lincoln Boulevard. These landscape improvements will bring additional truck trips and may require intermittent one-way closures on Girard Road.
Battery Tunnel Tops
February 2020 through Winter 2020
As part of our work to restore areas of the park disturbed by Presidio Parkway construction, we’re creating several acres of new public open space on top of the highway tunnels north of the National Cemetery (adjacent to Lincoln Blvd.) The “Battery Tunnel Tops” will feature a new multi-use section of the Presidio Promenade and offer sweeping views of the Golden Gate, Angel Island, and Alcatraz. Tree and brush removal began in February of 2020. An interim lane closure of Lincoln Boulevard begins in March. Soil movement and heavy landscape work will occur over the summer beginning in June. The project will take eight to ten months to complete.
Crissy Field Next
Crissy Field Next aims to enhance the area’s current uses, while improving ways to gather, create, and play. We kicked off the project in fall 2018, receiving feedback from hundreds of people. See the first round of design concepts online at
