Long-Delayed Polk Contra-Flow Protected Bike Lane Jumpstarted by DPW

In a surprising development, the Department of Public Works broke ground today on a contra-flow, protected bike lane on the two southernmost blocks of Polk Street, from Market to Grove Streets (at City Hall), which are currently one-way southbound. By Bike to Work Day, two of the city’s busiest bicycling streets are expected to be linked with the first bike lane in San Francisco to be protected with a landscaped median, against the flow of motor traffic.

The short but vital connection, first proposed by the city ten years ago and included in the SF Bike Plan, was threatened with yet another year of delay due to poor coordination and a missed contracting deadline. But DPW Director Mohammed Nuru was apparently convinced by the SF Bike Coalition that the project should become a top priority. The SFBC credits Nuru with kickstarting construction, said Executive Director Leah Shahum.

“When they see there’s a problem, there’s often more they can do to get things back on track, and they were able to do it in this case,” she said. “I can’t emphasize how important these two blocks are for so many people. This is going to be a game-changer for helping people ride where they need to go in a safer, more legitimate way.”

Currently, bicycle commuters have no legal way to turn from eastbound Market onto northbound Polk, except to travel a block ahead to Larkin, a one-way, heavily-trafficked three lane street with no bike lane. They must then turn left onto Grove to get back on to Polk.

To access the new contra-flow bike lane, which will replace an existing car parking lane, people bicycling on eastbound Market will have a new bike box to wait in at the intersection with 10th Street before making the turn on to Polk.

“With all the new developments, this is going to be a great way to connect a whole new community in mid-Market with the businesses on Polk Street,” said Shahum.

It’s important to note that the contra-flow lane project is being managed separately from the contested plans for partial protected bike lanes for Polk north of McAllister Street.

The existing southbound bike lane on the southern stretch of Polk will also be widened with a buffer zone and plastic posts on teh block south of Hayes Street, said DPW spokesperson Rachel Gordon. Since that bike lane runs between a parking lane and traffic lanes, it’s unclear if parking will be removed on that side of the street. No southbound bike lane improvements appeared in the Bike Plan design as of 2012, and they appear to be a recent addition.
