Kankakee County Bridge Snapshot
According to the Federal Highway Administration's 2024 National Bridge Inventory, Kankakee County ranks #32 of 102 Illinois counties with at least 5 public highway bridges on Poor-condition share (lower share ranks better; currently 6.4%). Kankakee County, Illinois contains 344 public highway bridges. Roughly 40.1% are rated “Good,” 53.5% “Fair,” and 6.4% “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.

Kankakee County's Poor-condition bridges carry 79,175 vehicle crossings a day
That is 10.2% of the county's reported daily bridge traffic on 6.4% of its bridges: Poor-condition structures carry more traffic than their share of the inventory. Each Poor bridge averages 3,599 crossings a day against 1,505 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.

33.4% of Kankakee County's bridges have passed the 50-year mark
115 of the 344 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 40.1% 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 18.3% of the county's Poor-condition bridge traffic
FAI-57 SB over ILL 17, built 1955, carries 14,450 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 22-bridge count understates how much of the daily burden sits on a single crossing.
