Essex County Bridge Snapshot

According to the Federal Highway Administration's 2024 National Bridge Inventory, Essex County ranks #13 of 13 Massachusetts counties with at least 5 public highway bridges on Poor-condition share (lower share ranks better; currently 17.2%). Essex County, Massachusetts contains 395 public highway bridges. Roughly 15.9% are rated “Good,” 66.8% “Fair,” and 17.2% “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. Use the “Sort by” controls to change the ordering, and click any row for its reported inspection date, traffic count, and condition fields.

Essex County's Poor-condition bridges carry 2,590,672 vehicle crossings a day

That is 21.8% of the county's reported daily bridge traffic on 17.3% of its bridges: Poor-condition structures carry more traffic than their share of the inventory. Each Poor bridge averages 38,098 crossings a day against 20,809 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 394 of 395 bridges in this county that report an average daily traffic count. Source: FHWA National Bridge Inventory, 2024 release.

73.4% of Essex County's bridges have passed the 50-year mark

289 of the 394 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 15.9% 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.

One structure carries 5% of the county's Poor-condition bridge traffic

US 1 NEWBRPRT TPK over I 95 /ST128, built 1963, carries 128,520 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 68-bridge count understates how much of the daily burden sits on a single crossing.

Share is of the 2,590,672 daily crossings on Poor-rated bridges that report a traffic count. Source: FHWA National Bridge Inventory, 2024 release.
