SFMTA crews were out striping bike lanes on Portola Drive today from O’Shaughnessy Boulevard to St. Francis Circle. The new lanes complement those striped on the rest of the street in recent months.
Streetsblog reader and Portola resident Mark Dreger reported spotting the crews this morning, noting that the project will provide a bicycling connection “on a street with no good parallel alternative for bicycling.”
Portola, which runs alongside Twin Peaks, is a road fraught with harrowing high-speed car traffic. It’s also the only direct road connecting the west end of Market Street to the intersection of Sloat Boulevard and West Portal Avenue, also known as St. Francis Circle, in the Parkside neighborhood.
The new bike lanes should provide some room for a more comfortable ride. The reduced width of the other traffic lanes, noted Dreger, “should also serve to traffic calm the street a bit.”
The project is part [PDF ] of the San Francisco Bike Plan currently being rolled out by the SFMTA. The lanes connect with a buffered bikeway striped on Laguna Honda Boulevard  in February, which connects to the Inner Sunset and areas north.
