A secretive group is painting crosswalks in Los Angeles where they say the city has failed to provide basic infrastructure to protect walkers — and while Streetsblog would never suggest that advocates across America follow their lead, it’s worth noting the wealth of resources available to would-be tactical urbanists…purely for entertainment purposes, of course.

The anonymous DIY traffic engineers behind Crosswalk Collective LA broke the internet last week when NPR profiled their efforts to bring high-visibility walking infrastructure to overlooked streets in the City of Angels. The fine folks at Streetsblog LA praised the initiative as well, noting that they hope “these new crosswalks last a while.”
