The latest information on project activities, road closures, and detours.
For approximately one month, periodic lane closures and night work are scheduled along southbound Highway 101 at the northbound Highway 101 hook ramp and between the Battery and Main Post Tunnels. Lane closures are required for crews to prepare the highway median for landscaping.
Beginning the week of January 3, for approximately two months, crews are scheduled to install underground stone columns north of the Main Post Tunnels to stabilize the soil for seismic safety. Large rigs with vibrating columns will inject rock into the ground, creating three-foot diameter, 50-foot-deep foundations of compacted material in approximately 3,500 locations.
Through early March, McDowell Avenue is scheduled to be fully closed overnight to continue storm drain installation in the center of the roadway. Overnight work along McDowell Avenue is scheduled for Sunday through Thursday nights, from 10:00 p.m. until 6:00 a.m. the following morning.
Work continues to restore full operations to various parking lots in the Presidio, which are scheduled to be complete in April 2017. The Swords to Plowshares parking lot is now open to the public.
Beginning in mid-September, crews will prepare to relocate Building 201 and reconstruct the southern portion of Halleck Street, kicking off overall reconstruction of the Halleck Street streetscape. This work is expected to continue through early 2017.
The Presidio Parkway project team has been working hard to address design, environmental and regulatory approvals for the final elements of construction. Over the coming months, Doyle Drive and the Presidio will be a beehive of activity, with site restoration, paving and landscaping occurring across the corridor. Upcoming work (daytime, Monday-Friday, and occasional Saturday and night work) will lay the groundwork for the Presidio Tunnel Tops, the project team’s shared vision for a magnificent 14-acre landscape that integrates the San Francisco Bay waterfront with the Presidio’s historic Main Post district. Please reach out to the Public Information Office with any questions (contact information on second page), and thank you for your patience during construction!
The Presidio Parkway final design provides new connections from the Presidio to Crissy Field for pedestrians and bicyclists to enjoy. In addition to continuous sidewalks and bicycle lanes along Girard Road opening in late September, future landscaping and increased green space will create opportunities for outdoor recreation for years to come.
