La Crosse County Bridge Snapshot

According to the Federal Highway Administration's 2024 National Bridge Inventory, La Crosse County ranks #39 of 72 Wisconsin counties with at least 5 public highway bridges on Poor-condition share (lower share ranks better; currently 6%). La Crosse County, Wisconsin contains 249 public highway bridges. Roughly 41% are rated “Good,” 53% “Fair,” and 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. Use the “Sort by” controls to change the ordering, and click any row for its reported inspection date, traffic count, and condition fields.

La Crosse County's Poor-condition bridges carry 19,736 vehicle crossings a day

That is 1.4% of the county's reported daily bridge traffic on 6% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 1,316 crossings a day against 5,423 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 249 of 249 bridges in this county that report an average daily traffic count. Source: FHWA National Bridge Inventory, 2024 release.

30.5% of La Crosse County's bridges have passed the 50-year mark

76 of the 249 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 41% 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 66.9% of the county's Poor-condition bridge traffic

IH 90 WB over CTH M, built 1968, carries 13,200 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 15-bridge count understates how much of the daily burden sits on a single crossing.
