District of Columbia bridge safety

According to the Federal Highway Administration's 2024 National Bridge Inventory, condition ratings, load ratings, and Poor-condition shares for every public highway bridge in District of Columbia.

257
Public bridges
34.6%
Good condition
1.9%
Poor condition

District of Columbia holds 257 public highway bridges (#52 of 52 by inventory) with a 1.95% Poor share (#47 of 52 by Poor share).

That is 1.9% of the state's inventory, against an average of 7.5% across the 54 states and territories with Poor-rated bridges on file, which places it 6 of 54 ordered from the lowest Poor share upward. A bridge is rated Poor when its weakest applicable component scores 4 or below on the inspecting agency's 0-9 scale, so the category is a maintenance and funding signal rather than a closure order or a live crossing-safety verdict.
