The #Pittsburgh #bridge that collapsed was steel, rated "poor". From http://bridge.watch, here are #steelbridges with similar usage rated "poor". https://bridge.watch/?plot_type=year_built&material=3%2c4&service_under=5&ratings=4&min_traffic=14500 (I added permalinks) #BridgeCollapse #infrastructure #Infrastructurebill @USDOTFHWA@twitter.com @ASCETweets@twitter.com @USDOT@twitter.com

95% of #bridges in Illinois with 200 ft or longer spans are #steelbridges (231/245). 30% of them are in poor shape (all but one were built prior to 1980), and have an average traffic volume of 23000 vehicles/day #Infrastructurebill #bridgeengineering http://bridge.watch

Interesting things I've found so far: New York is *big* on #steelbridges, 70% of which are in fair or poor condition. https://bridge.watch #InfrastructureWeek #InfrastructureBill #dataviz
