SFMTA Adds More Green Treatments to Bike Lane Merging Zones

The SFMTA recently added green paint to increase the visibility of bike lanes around the city at five intersections where drivers merge across bicycle traffic.

The SF Bicycle Coalition's Flickr page features the new treatments at the intersections of Division and 9th Streets, Grove and Polk Streets, and the Embarcadero at Bryant Street. The SFBC also said they spotted the treatment at Howard and 9th, and Streetsblog SF founding editor Bryan Goebel snapped a photo of one on eastbound Market Street at Buchanan (across the street from the entrance to the Wiggle).

An SFMTA document [PDF] says the agency chose the locations to evaluate how the treatments affect merging behavior as drivers cross over bike lanes into right-turn lanes.

Check out more photos after the break.
