Just read this in the latest sfbike.org newsletter:
From the Hills to Flatlands, Bike Lane Links Add Up
The SF Bicycle Coalition is proud to announce that bike lanes on Portola Drive are making their way to the pavement soon. These bike lanes, approved thanks to many hours of work of Bicycle Coalition volunteers, will create a safer connection for people commuting over Twin Peaks on Portola Drive between Corbett Avenue and O'Shaughnessy Boulevard, and connect to the recently completed bike lanes on Laguna Honda.
Good deal! It'll make my commute much safer, a car this morning didn't know that I could take the lane.
