Each year since 1979, the Better Roads Bridge Inventory has examined the conditions of the nation’s bridges.
This year, departments of transportation in 39 states and the District of Columbia responded between August 5 and September 28 to the annual Equipment World survey. The survey was sent to the 51 bridge engineering divisions of the District and all the 50 states. For those that did not respond, we used data from the Federal Highway Administration’s 2019 National Bridge Inventory.
For a rundown of how the states stack up in 2020, looking at the five states with the lowest percentage of bridges rated poor and the five states with the highest percentage. This year, we also included a ranking of all 50 states and D.C. by the percentage of poor-rated bridges, as well as a breakdown of the number and percentage of bridges rated good and fair.
