It’s officially rideable: The left-turn pocket and traffic signal connecting Market and Valencia Streets is finished as of today, the SFMTA announced on its Livable Streets Facebook page. Finally, the bicycling gates from Market to the Mission have been opened to people who don’t feel comfortable merging across three traffic lanes and a set of streetcar tracks to turn left with car traffic. A simple but incredibly useful upgrade.

The green-backed sharrow (not pictured) in the center of the street seems like a nice touch, but the concrete divider in the bike lane has drawn some skepticism from observers during construction. If you pass by it on your commute today, let us know in the comments how it works for you.
