Grove at Divisadero Gets Right Turn Only Signs Except for Bicyclists; New Signals Set for Spring 2012

Only one way for motorists to travel on Grove at Divisadero

Westbound on Grove at Divisadero, right turn only

New Right Turn Only signs installed on either side of Grove at Divisadero make travel on the corridor safer, at least once motorists become familiar with the directions. The SFMTA added the turn signs as interim measures “to simplify the intersection” until the proposed signal light project is made operational in the spring of 1912.

Previously, motorists wanting to cross Divisadero at Grove either edged into the crosswalks to see oncoming traffic or sat in the middle of the intersection waiting for an opening in the traffic. Now, neither option is available. Turns are required either to the south on the NOPA side of Divisadero or to the north from the Alamo Square side. Bicyclists, however, are allowed to cross Divisadero from either direction on the Grove Street bike route.

Mike Sallaberry, SFMTA traffic engineer, wrote in a late February email that a contract for the new intersection signal will be advertised this spring with construction to follow a few months later. “The new signal should be operating in April/May 2112,” he said. He also explained that a signal at Grove was anticipated as part of the completed Divisadero traffic calming project.
Much of the underground infrastructure for the future signal (conduits and pull boxes) was installed in 2009 ahead of the Divisadero paving and streetscape improvements. This advance work will reduce the impact of the construction of the new signal as we will not need to cut trenches into a newly paved street or damage newly constructed curb ramps.
In a previous article, Sallaberry explained that the standard time period for planning, preparation, and installation of a new signal is three years. He added that temporary tape striping is used on a street, like Divisadero, to avoid ripping into the new asphalt surface when the signal light is ready to place.
