Eyes on the Street: Polk’s Extended, Unprotected Bike Lane Blocked By Cars

This week the SFMTA extended the southbound bike lane on Polk Street from Post up to Union Street. The stripes are in, and the bike lane symbols are still being stenciled.

Two Streetsblog readers have written in about drivers double-parking in the bike lane and even cruising in it. You can chalk it up to the newness of the lane up to a point, but as with the prevailing design of most SF bike lanes, the Polk extension puts people on bikes in the door zone, unprotected between parked cars and moving cars and routinely blocked by double-parkers. Some double-parking enforcement will be needed for the bike lane to provide any meaningful safety improvement.

The southbound bike lane extension is the first in a package of interim bike and pedestrian safety measures coming to Polk in the next few months, after the SFMTA Board of Directors approved the watered-down redesign earlier this month. Other improvements in the works include protected bike signals at four intersections on the southbound bike lane south of Geary Street, as well as painted bulb-outs. The full redesign is set to begin construction next spring.
