Maine 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 Maine.

2,518
Public bridges
24.9%
Good condition
15.4%
Poor condition

Maine holds 2,518 public highway bridges (#45 of 52 by inventory) with a 15.41% Poor share (#4 of 52 by Poor share).

That is 15.4% 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 50 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.

Maine in the national condition pattern

Each point is a state or territory in the FHWA NBI; the highlighted point is this profile.

Inventory size and Poor-condition share are different measures: Maine has 2,518 bridges and a 15.4% Poor-condition share in the 2024 NBI, rank #50 of 54 jurisdictions ordered from the lowest share upward. The dashed comparisons mark the national average state rate and the midpoint of the plotted inventory range; neither is a live safety or closure threshold.
