Presidio Parkway Corridor Improvements

​​​​​​​​​​​​​​​​​​​​​Presidio Tunnel Tops and Other Open Space Improvements Set to Begin

(Updated May 20, 2019) - Now that construction of the Presidio Parkway to the Golden Gate Bridge is complete and the surrounding land has been returned to the Presidio Trust, we’re preparing to make big improvements to beautify the park, expand natural habitat, improve walking paths, and create new experiences for visitors.

Three projects will begin over the next few months, with the first scheduled to start in early June. Since these projects are near each other and the project schedules overlap, we want to give you an overview of the timelines, activities, and expected impacts, which include increased truck trips and road closures with detours.

We appreciate your patience and will provi​de periodic updates. Should you have questions, contact us at presidio@presidiotrust.gov.​

Project Improvements

Presidio Tunnel Tops Soil Delivery – June through July 2019

We are bringing in soil to cover the Presidio Parkway tunnels so we can create a new 14 -acre landscape with vistas and trails on top. A high volume of delivery trucks will travel to the site for two months. In October, the Transit Center will close for remodeling, and a temporary transit stop and restrooms will be located nearby. We’ll provide full details as we approach that date. Construction of the Tunnel Tops will continue through fall 2021.

Crissy Marsh

Crissy Marsh Expansion at Quartermaster Reach – July 2019 to January 2020

We are expanding Crissy marsh by seven acres just east of Halleck Street. This is the latest step in the 20-year restoration of the park’s largest watershed. To expand the marsh, we will 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 July through January 2020, with a detour along Halleck Street. The driveways in and out of East Beach will not be affected. We will plant thousands of salt marsh and riparian plants beginning in early 2020.

Girard Road

Beautification of Girard Entry Corridor – August 2019 to Spring 2020

We’re beautifying the Presidio’s entrance along Girard Road in conjunction with new landscaping from the Presidio Parkway / Highway 101 interchange to Lincoln Boulevard. This work will bring additional truck trips and may require intermittent one-way closures on Girard Road.
