San Francisco’s first on-street, two-way protected  bikeway  is nearly complete, featuring bicycle traffic signals and green intersection bike markings . The bikeway, which is separated from motor vehicles by a fence and concrete median, provides a safer connection from Bayview and Hunter’s Point to Third Street and the north-south bike lanes on Illinois Street.
“It’s exciting to see this much-needed improvement in the southeastern part of San Francisco, where there is so much potential for great bicycling,” said Leah Shahum, executive director of the SF Bicycle Coalition. “We are hearing from a lot of people that this is making a real difference in improving their bike commutes. We look forward to a lot more improvements in the area , such as Bayshore Boulevard and the eastern half of Cesar Chavez.”
Construction of the bikeway, a project of the Port of SF and the SF Municipal Transportation Agency [PDF ], began in March and was originally scheduled to be completed in May, though it’s unclear why it was delayed. The fence was completed in May, and the striping was finished by July. The bike traffic signal at the Mendell Street intersection was activated last week, though an SFMTA staffer said there’s a delay with activating the signal at the three-way intersection of Cargo Way, Illinois and Amador Streets, at the bikeway’s west end. There, the bikeway splits into separate one-way painted bike lanes that end at Third Street.
The bike traffic signals create a dedicate phase for bike traffic to cross, separate from another signal phase for motor vehicles to turn across the path of the bikeway.
Green-backed sharrows were also installed to guide bicycle riders through the Illinois/Amador intersection, and in the coming weeks green paint will also be added to a waiting area for bicyclists crossing Cargo Way onto northbound Illinois. At the east end of the bikeway, the intersection of Cargo Way and Jennings Street was converted from a two-way stop sign intersection to a four-way stop.
One other notable touch added to the project is the visible wayfinding signage at the bikeway’s west entrance — certainly not a typical feature on bike routes in SF.
