The city’s Vision Zero program two years ago and got to work quickly. The city expanded its bike-lane network 38 percent in 2019 and 2020, so that its total on-street network of 16.3 miles is now nearly half (47.3 percent) of the city’s 33 miles of streets. (Most of those lanes are not protected, however: The 1.04 miles of protected lanes comprise 6.4 percent of the on-street bike network.)
