Whatcom County Owned Bridge Sufficiency Ratings Number of County Owned Bridges > 20 feet

About this metric.

  • Why bridges over 20 feet? The federal government requires agencies to report the condition of bridges over 20 feet annually.
  • How is the bridge sufficiency rating determined? The bridge sufficiency rating is determined by the results of annual inspections, combining structural and functional ratings. These ratings are used to help determine federal bridge replacement and rehabilitation funding levels to the states.

What does the data show? In 2016 there were 131 Whatcom County Owned bridges that were in fair or better condition, 4 in poor condition, and 1 in very poor condition. The sufficiency rating doesn't necessarily indicate a bridge's ability to carry traffic loads. It helps determine which bridges may need repair or replacement, not potential for collapse.
