I-5 Operations and Demand Analysis

Planning study news

WSDOT has completed the I-5 Operations and Demand Analysis and the report is now available for viewing.

July 2018 - September 2020


The Northwest Region Mount Baker Area is leading this effort to address several mobility challenges along segments of the I-5 corridor within the urban area of Bellingham (MP 250 to MP 258). Congestion occurs regularly during peak travel at the I-5 interchanges and on the connecting regional arterials. WSDOT conducted this analysis to understand when and where congestion occurs, and the travel characteristics of users of this section of the I‐5 corridor. WSDOT will use this information to assess the need for operations and demand management strategies, and to evaluate their effectiveness.
