Clear Creek County Bridge Snapshot
According to the Federal Highway Administration's 2024 National Bridge Inventory, Clear Creek County ranks #45 of 64 Colorado counties with at least 5 public highway bridges on Poor-condition share (lower share ranks better; currently 6.5%). Clear Creek County, Colorado contains 77 public highway bridges. Roughly 36.4% are rated “Good,” 57.1% “Fair,” and 6.5% “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.

Clear Creek County's Poor-condition bridges carry 156,400 vehicle crossings a day
That is 13.9% of the county's reported daily bridge traffic on 6.5% of its bridges: Poor-condition structures carry more traffic than their share of the inventory. Each Poor bridge averages 31,280 crossings a day against 12,112 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.

55.8% of Clear Creek County's bridges have passed the 50-year mark
43 of the 77 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 36.4% 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 30.1% of the county's Poor-condition bridge traffic
I 70 FRONTAGE RD over CLEAR CREEK SR, built 1936, carries 47,000 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 5-bridge count understates how much of the daily burden sits on a single crossing.
