Whatcom County Owned Arterial Surface Condition

About this metric.

  • What are arterials and why are they important? Arterials provide the highest level of service at the greatest speed for the longest uninterrupted distance, with some degree of access control. In 2019, 81% of all traffic on county roads was on paved arterials.
  • How is the pavement surface condition determined? Counties are required by CRAB to inspect their arterials every two years. Arterials are given a numerical score from 1 (very poor) to 100 (excellent).

What does the data show? In 2019, 96% of arterials have a rating of fair or better and 4% (16 miles) are in poor or very poor condition.
