From SFMTA:
Beginning at 6 a.m., Sunday until 9 p.m., Sunday, Sept. 15, the right-hand travel lane of northbound The Embarcadero between Washington and Green streets will be closed temporarily for the implementation of a two-way cycletrack for the America’s Cup Finals races.
This bikeway will run between Washington Street, north of the Ferry Building, to the midblock pedestrian crossing at Pier 23, between Lombard and Green streets. The facility will provide additional capacity for bikes in the areas that are expected to experience the greatest number of visitors to the America’s Cup events.
Police barricades will be used for the cycletrack. There will be gaps at each intersection and midblock crossing. Local, loading and emergency access will be allowed.
No parking will be allowed along the east side of northbound The Embarcadero while the bike facility is in place. There will be signs to alert drivers of the lane closure.
The SFMTA recommends motorists traveling northbound in the vicinity of The Embarcadero to allow plenty of travel time and to use Sansome Street or Kearny Street as alternate routes.
For details of traffic re-route, please refer to the attached America’s Cup Embarcadero Alternate Route Map.
