From 2018 to 2020, the Washington State Department of Transportation (WSDOT) worked with agency partners including the city of Bellingham, city of Ferndale, Lummi Nation, Port of Bellingham, Whatcom Transportation Authority (WTA) and Whatcom Council of Governments (WCOG) to better understand mobility challenges along the Interstate-5 (I-5) corridor through Bellingham. Regular congestion happens during peak travel at I-5 interchanges and on connecting major streets.The resulting I-5 Operations & Transportation Demand Analysis helped agencies to understand when and where congestion occurs and the travel characteristics of users of this section of I-5. The Whatcom I-5 Operations Survey Story Map communicates these survey results to planning partners and the public. Please contact Katie Bunge at Katarina.Bunge@wsdot.wa.gov regarding this data product.
