Streetfilms: Bike-Centric Left Turn Markings on San Francisco’s “Wiggle”

"The Wiggle" is one of San Francisco's most beloved bike routes, guiding riders between two nasty hills. It even has its own Wikipedia entry.

It's so popular, it's hard to stand there at any time of day and not see packs of cyclists passing through! (Note: This is a camera person's dream.) Recently, after a judge partially lifted the legal injunction on new bike amenities in the city, San Francisco striped a unique combo to help cyclists safely navigate one of the Wiggle's twists. A green bike box on Scott Street -- believed to be California's first -- allows riders to safely wait and queue up for a dedicated left turn lane which runs the length of the entire next block.

Andy Thornley from the San Francisco Bike Coalition showed us around to see how it works -- and we heard from riders who voiced their appreciation.
