Northbound San Jose Ave Goes on Road Diet, Gains Buffered Bike Lane

The northbound side of speed-plagued San Jose Avenue north of 280, a.k.a. the Bernal Cut, is getting a road diet and buffered bike lane that matches the geometry of the street's southbound side. SFMTA crews were out today, re-striping the road and installing plastic posts in the buffer zone.

The change is far overdue for neighbors who have pushed for traffic calming along the Bernal Cut for decades, particularly since Caltrans invited more speeders to the street by adding a 280 off-ramp lane over 20 years ago.

"The San Jose pilot is the result of decades of community organizing around making the Bernal Cut safer for everyone," said Kristin Smith, communications director for the SF Bicycle Coalition. She noted that the improvements "will make this critical part of our North-South Route safer," contributing to the SFBC's Connecting the City vision of a citywide bike route network safe enough for anyone age 8 to 80 to use. "We look forward to seeing following improvements in the area."

The bike lane upgrade is the first part of a two-phase pilot project, which was originally supposed to start construction in March. By reallocating one of San Jose’s three northbound traffic lanes to a wider bike lane and buffer zone, the SFMTA hopes to bring the number of drivers traveling faster than 35 mph down to 15 percent or less. If traffic speeds don’t drop below the target, Caltrans will remove the off-ramp lane that it added in 1992, in order to accommodate traffic re-routed away from Loma Prieta earthquake freeway repairs.

Currently, San Jose has a speed limit of 45 mph, and 15 percent of drivers travel faster than 48 mph. On the off-ramp, that number is 57 mph.

Spencer Goodwine came across the street construction on his bike ride to work, finding the entire northbound side of San Jose closed to cars. "It was pretty awesome getting all three car lanes to my self," he said.
