Champaign County Bridge Snapshot
According to the Federal Highway Administration's 2024 National Bridge Inventory, Champaign County ranks #65 of 102 Illinois counties with at least 5 public highway bridges on Poor-condition share (lower share ranks better; currently 8.7%). Champaign County, Illinois contains 727 public highway bridges. Roughly 58.9% are rated “Good,” 32.5% “Fair,” and 8.7% “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.

Champaign County's Poor-condition bridges carry 179,635 vehicle crossings a day
That is 10.3% of the county's reported daily bridge traffic on 8.7% of its bridges: Poor-condition structures carry more traffic than their share of the inventory. Each Poor bridge averages 2,851 crossings a day against 1,460 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.

30.4% of Champaign County's bridges have passed the 50-year mark
221 of the 727 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 58.9% 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 23.3% of the county's Poor-condition bridge traffic
I-74 over US 45(FAP 800), built 1956, carries 41,900 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 63-bridge count understates how much of the daily burden sits on a single crossing.
