State profile · Near median Poor share

Massachusetts 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 Massachusetts.

5,295
Public bridges
25.1%
Good condition
8.9%
Poor condition

Massachusetts holds 5,295 public highway bridges (#35 of 52 by inventory) with a 8.88% Poor share (#14 of 52 by Poor share).

That is 8.9% 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 39 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.
