Boston city passes law for protected bike lanes

City Lab - The Boston suburb of Cambridge mandated that protected cycling lanes be installed on all streets that are slated for reconstruction under existing city plans.

The ordinance appears to be the first of its kind in the U.S., and allows Cambridge—a dense university town that already has an unusually high share of bike commuters—to ascend into the ranks of the most progressive bicycling cities in the country. Local law now requires the city to erect vertical barriers between cyclists and cars on any roadway that’s rebuilt, expanded, or reconfigured if it’s part of the proposed 20-mile network of separated lanes known as the Cambridge Bicycle Plan. only in “rare circumstances” where the city manager must cite physical or financial restraints will there be exceptions.

This doesn’t mean that pylons and planters will erupt in the streets around Harvard overnight. Permanent, protected lanes will only appear as the city advances those planned upgrades, which could mean that progress moves slowly. As Cambridge Day reported, last year the city only built one mile of new protected bike lanes.
