Public highway bridges in Massachusetts
State profile · Near median Poor share
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.
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.

Pre-1950 construction accounts for 26.1% of the 5,295 bridges with a recorded original year in Massachusetts. Era bands are orthogonal to the Poor-share ranking above.
Adjacent states by Poor-condition share (lower share = better)
States are ranked by the share of bridges whose lowest applicable component rating is 4 or below. This describes recorded condition; it does not measure funding effectiveness or live crossing safety. States here sit immediately above and below Massachusetts on the same metric.

What to do with this
Use Massachusetts's inventory picture to drill to a county or a specific span.
NBI condition ratings are inventory snapshots, not live crossing-safety verdicts.
Every figure on PlainBridges is rendered directly from federal source data, no number is typed in by an editor. Massachusetts Good/Fair/Poor shares and county rollups on this page are computed from the same NBI extract as the national boards; no figure is typed in by an editor. See our editorial standards & corrections policy, the methodology behind these numbers, or report a data error. Data current as of 2024 NBI release. NBI condition categories reflect the latest reported inventory record, not a live safety, closure, or travel decision.
