Hennepin County Bridge Snapshot

According to the Federal Highway Administration's 2024 National Bridge Inventory, Hennepin County ranks #44 of 87 Minnesota counties with at least 5 public highway bridges on Poor-condition share (lower share ranks better; currently 4.1%). Hennepin County, Minnesota contains 936 public highway bridges. Roughly 40.6% are rated “Good,” 55.3% “Fair,” and 4.1% “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.

Hennepin County's Poor-condition bridges carry 334,931 vehicle crossings a day

That is 1.6% of the county's reported daily bridge traffic on 4.1% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 8,814 crossings a day against 22,491 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 936 of 936 bridges in this county that report an average daily traffic count. Source: FHWA National Bridge Inventory, 2024 release.

31.2% of Hennepin County's bridges have passed the 50-year mark

292 of the 936 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 40.6% 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 13.2% of the county's Poor-condition bridge traffic

I 494 over Minnesota River, built 1981, carries 44,357 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 38-bridge count understates how much of the daily burden sits on a single crossing.
