Cities around the United States have built nearly as many protected bike lanes in the past two years as they did in the previous 140.

The Green Lane Project released an updated inventory of protected bike lanes around the country, noting the quick rate of adoption for the most robust form of bike infrastructure. "Between 1874 and 2011, only 78 of these facilities were built nationwide. Our inventory shows that this number nearly doubled to 138 protected bike lanes witin [sic] the first two years of the Green Lane Project. 60 percent of the new lanes were in the Green Lane Project's six founding focus cities: Austin (6), Chicago (17), Memphis (1), Portland (2), San Francisco (9) and Washington DC (2). By the end of 2014, 191 protected lanes were on the ground across the country."
The main purpose of the post is to share an updated inventory of current protected bike lanes in North America, which is available in Google Drive as well as for download, but the Green Lane project has also prepared the video below to explain the differences between protected bike lanes and other forms of bike infrastructure.
