Bicycle Infrastructure

New green-backed sharrows, Muni shelters, planters, art murals and more were installed in recent weeks as part of the ongoing improvements to the bike and transit hub at Duboce Avenue and Church Street.

Second Street could get protected bike lanes, sidewalk extensions, lane reductions, greening and more under options presented to residents last night by the SF Department of Public Works and the Municipal Transportation Agency.

The SF Municipal Transportation Agency released its four-year State of Cycling Report [PDF] this week. While the findings in the report may not be new to those keeping an eye on the growth of bicycling in San Francisco -- which has jumped 71 percent from 2006 to 2011 -- bike advocates say it highlights the city's faltering plans to roll out bike infrastructure in comparison to other cities.

A plan for sweeping safety improvements on deadly Masonic Avenue was unanimously approved by the SF Municipal Transportation Agency Board of Directors yesterday. It's the final decision needed to move the project forward, though the SFMTA says planners still need to finalize the design and secure funding before it's implemented. The agency doesn't have a timeline for that yet, but construction is likely still a couple years off.

Chronicle columnist C.W. Nevius took another shot at stoking some bicycle controversy today with his latest fact-free piece sharing his "concerns" that bike lanes "may be on [a] crash course" with cars.

We reported last week that the SFMTA is considering testing out a two-way bike lane on the Embarcadero during the next America's Cup races in October, according to an agency report. However, America's Cup spokesperson Jane Sullivan tells us that the lane will only serve one-way traffic in the northbound direction, and no trial bike lane will be provided in the southbound direction.

A two-way protected bikeway along the Embarcadero could get a trial in the coming months. The SF Municipal Transportation Agency is considering implementing a temporary two-way bikeway along the waterfront during the next America's Cup events in October, according to an agency report. The agency is also developing plans for a more permanent bikeway along the Embaracdero near Pier 39, from Kearny to Powell Streets.

A section of the post-separated bike lanes on Portola Drive was removed last week and replaced with a design which the SF Municipal Transportation Agency says should be safer and easier for people on bikes to navigate. But at least one commuter who uses the lanes said the change is anything but safe.

San Jose -- which wants its central district to become the urban center of Silicon Valley -- hopes to build the Bay Area's most bike-friendly downtown, where pedaling to work, school or the farmers market is "safe, convenient and commonplace" for people of all ages. The vision includes Long Beach-inspired bicycle-friendly business districts, where merchants would wholeheartedly embrace bike-riding shoppers and diners.
