For Immediate Release
RESCHEDULED: Overnight Closure of Northbound Hwy 1 on May 11, 1:00 a.m. - 6:00 a.m.
SAN FRANCISCO - Visible progress is being made on the approach to the Golden Gate Bridge as Phase II construction continues on the Presidio Parkway project. Three new tunnels and the new northbound High Viaduct are well underway, while the Highway 1/101 realignment is advancing to build safety shoulders and a landscaped median for the future roadway.
On Sunday, May 11 from 1:00 a.m. to 6:00 a.m., northbound Highway 1 will be closed from Lake Street to the Highway 101 interchange to shift traffic to a new, temporary alignment that will allow crews to continue building the final roadway between Highway 1 and the Golden Gate Bridge Toll Plaza.
In the new alignment, which will be in place for approximately one month, motorists on northbound Highway 101 must be in the rightmost lane to access the last San Francisco exit at Merchant Road. A simulation video of the new alignment is available on the project website at www.presidioparkway.org/video.
While a majority of Presidio Parkway construction occurs away from the active roadway, work between the Highway 1/101 interchange and the Golden Gate Bridge must occur within the current roadway alignment, requiring construction to progress in phases as sections of the new roadway are built. Phased construction allows traffic to continue moving on the temporary alignment as construction of the new roadway occurs.
Early morning ramp closures, nighttime work and additional roadway realignments will occur as construction progresses throughout the corridor.
Official Detour during NB Highway 1 Closure - May 11 from 1am to 6am
Detour signage will direct motorists from Highway 1 to Highway 101 via Geary Boulevard/Van Ness Avenue/Lombard Street. These detour routes were selected because they are able to carry a high volume of traffic and use relatively flat streets; the signed detour must be accessible to all vehicles, including large trucks, motor homes, etc. However, most people will choose their alternate route based on what is most convenient for their trip.
Drivers should be cautious while adjusting to the new alignment. The closure date is subject to change due to weather and unforeseen conditions.
