Bad Bridges is a Glitch app that lets you "find out how many bridges you cross while traveling around Pittsburgh"—oftentimes many—and which of them are structurally deficient—also many.
Creator Rainy Sinclair: "I made it on @glitch using publicly available data from @PennDOTNews, the google maps API, and some super hacky javascript."
For example, getting from the War Streets to Homestead traverses 30 bridges, 3 of them in structurally deficient condition and 24 of them not so bad, really. [via joe janecek]
