Gogebic County Bridge Snapshot
According to the Federal Highway Administration's 2024 National Bridge Inventory, Gogebic County ranks #69 of 83 Michigan counties with at least 5 public highway bridges on Poor-condition share (lower share ranks better; currently 17.3%). Gogebic County, Michigan contains 104 public highway bridges. Roughly 23.1% are rated “Good,” 59.6% “Fair,” and 17.3% “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.

Gogebic County's Poor-condition bridges carry 10,533 vehicle crossings a day
That is 11.6% of the county's reported daily bridge traffic on 17.3% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 585 crossings a day against 376 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 104 of 104 bridges in this county that report an average daily traffic count. Source: FHWA National Bridge Inventory, 2024 release.
53.8% of Gogebic County's bridges have passed the 50-year mark
56 of the 104 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 23.1% 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 80.5% of the county's Poor-condition bridge traffic
US-2 over POWDER MILL CREEK, built 1962, carries 8,481 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 18-bridge count understates how much of the daily burden sits on a single crossing.
