(Updated November 1, 2019) - This summer and fall we’ll begin several projects to create beautiful new national park experiences for our visitors.
We want to share an overview of the project locations, schedules, and activities. Two impacts are particularly noteworthy: 1) an increase in truck traffic, particularly during August and September, and 2) a six-month closure of a section of Mason Street east of Halleck Street, beginning in December.
Thank you for your patience during this work. Should you have any questions, please contact us at

About the Projects
Presidio Tunnel Tops Soil Delivery
August through September 2019
We are bringing in soil to cover the Presidio Parkway tunnels to create the Presidio Tunnel Tops - a new 14-acre world-class parkland with vistas, gardens, and trails (details at
PresidioTunnelTops.org). A high volume of delivery trucks will travel to the site for two months. Work hours are weekdays from 7 am to 5 pm. Construction of the Tunnel Tops will continue through fall 2021. Our thanks to the many community members who participated in the planning and design process, and our generous donors who have contributed to the implementation of this visionary project.
Temporary Transit Center
October 2019 through Fall 2021
This fall, the Presidio Transit Center will close for remodeling for two years to prepare for the opening of the new Tunnel Tops. A temporary transit stop and restrooms will be located in the Main Post parking lot across Lincoln Boulevard from the Visitor Center (see map). We’ll provide more details later this summer.
Fall 2019 through Spring/Summer 2020
We’re expanding Crissy Marsh by nearly 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 Spring/Summer 2020, with a detour along Halleck Street. The driveways in and out of East Beach will not be affected. Alternative routes will be available for bikes and pedestrians. We’ll plant thousands of salt marsh and riparian plants in Spring 2020.
Beautification of Girard Entry Corridor
October 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.
Crissy Field Next
Planning Begins Fall 2019
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
crissyﬁeldnext.org and tell us what you think! Public scoping begins in fall 2019.
