Public highway bridges in Maryland
State profile · Below median Poor share
Maryland 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 Maryland.
- 5,484
- Public bridges
- 32.3%
- Good condition
- 4.6%
- Poor condition
Maryland holds 5,484 public highway bridges (#34 of 52 by inventory) with a 4.56% Poor share (#38 of 52 by Poor share).
That is 4.6% 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 15 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.
