County profile · official public datasets
1,014 public highway bridges tracked in the FHWA National Bridge Inventory: 25.5% rated Good, 66.9% Fair, 7.6% Poor.
The verdict
According to the Federal Highway Administration's 2024 National Bridge Inventory.
Worcester County posts a higher-than-median Poor-condition share among rated counties in the state across large county bridge inventory.
Poor is an FHWA condition category from the lowest applicable component rating (4 or below), not a live crossing-safety or closure decision. Rankings cover counties with at least five public highway bridges.
According to the Federal Highway Administration's 2024 National Bridge Inventory, Worcester County ranks #7 of 13 Massachusetts counties with at least 5 public highway bridges on Poor-condition share (lower share ranks better; currently 7.6%). Worcester County, Massachusetts contains 1,014 public highway bridges. Roughly 25.5% are rated “Good,” 66.9% “Fair,” and 7.6% “Poor.” Poor means the lowest applicable deck, superstructure, substructure, or culvert rating is 4 or below on the 0–9 NBI scale. It is a condition category, not a live safety or closure decision.
Responsible agencies inspect covered bridges on risk-based intervals under current NBIS rules and submit inventory data to FHWA annually. The list below shows every NBI-tracked bridge in the county.

Share of 1,014 NBI-tracked bridges by lowest applicable component rating.
That is 6.1% of the county's reported daily bridge traffic on 7.6% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 12,467 crossings a day against 11,673 for a Good-condition one. A Poor rating is a condition category, not a closure or a live safety judgement; it means the lowest applicable component rating is 4 or below.
Computed over the 1,013 of 1,014 bridges in this county that report an average daily traffic count. Source: FHWA National Bridge Inventory, 2024 release.
665 of the 1,014 bridges with a recorded construction year were built in 1974 or earlier. Age alone is not a defect: a well-maintained older bridge can rate Good, and 25.5% of this county's inventory does. Even so, this older cohort is the population from which future Poor ratings are drawn, which is why the age profile below matters alongside the condition split above.
Cutoff derives from the 2024 release year minus a 50-year design life. Source: FHWA National Bridge Inventory, 2024 release.
I 290 EB over HWY E CENTRAL ST, built 1958, carries 65,611 vehicles a day, the most of any Poor-rated structure here. The county's Poor-condition exposure is concentrated rather than evenly spread, so the 77-bridge count understates how much of the daily burden sits on a single crossing.
Share is of the 959,932 daily crossings on Poor-rated bridges that report a traffic count. Source: FHWA National Bridge Inventory, 2024 release.

What this shows Construction peaked in the 1950s, when 224 of the county's bridges still in the inventory were built, which is 22.1% of those with a recorded year. That cohort is now 65 to 74 years old in the 2024 inventory. Its average build year (1963) matches the Massachusetts average (1961).
The 5 Massachusetts counties nearest Worcester County in number of bridges, with their condition splits. Its 7.6% Poor share is the 2nd-lowest of these 6. Its average build year of 1963 against a peer-group mean of 1960 is in line with the group.
