San Francisco is on its way to being the greenest, most bike-friendly city in the nation – at least that’s what Mayor Gavin Newsom believes.

On Monday, the mayor joined the bike community and the San Francisco Municipal Transportation Authority in rolling out the first stripe of a new bike lane on Townsend Street near Fourth Street. The project is the first of some 45 new bike lanes.

On Friday, the courts lifted a four-year-old injunction that had barred The City from moving forward with plans for new bike lanes and other infrastructure. During the ban there was a 54 percent increase in bicycling in San Francisco, Newsom said. The mayor thinks once the new bikes lanes are paved, The City will see another 50 percent increase in bike usage citywide.

And for all of these reasons, Portland, Oregon better watch out, according to Newsom. “I love Portland but I hate they are ahead of us on this,” Newsom said. “We are always No. 2 in the country in terms of our environmental record because of the bike network.

“Portland is finished,” Newsom said.  “With all due respect to the good mayor out there you are going down.”
