Ever since the L Street bike lane opened (and while DDOT was building it), for-hire sedans, delivery trucks, and other vehicles have consistently parked in the lane, despite signs, bollards, and new loading zones across the street or around the corner to serve buildings’ loading needs.

Photos from “Who’s Blocking the L St. Bike Lane Today?” on Tumblr.

Jay Corbalis created a Tumblr, Who’s Blocking the L St. Bike Lane Today? to collect photographs of these scofflaws. This is a great way to raise consciousness of how often it’s happening.

If you ride down the lane and encounter a blocker, take a picture of your own! You can submit them directly to be included on the site.
