West Bakerview/Interstate 5 Interchange Improvements

​​​​​​​​​Project Overview​: ES-0500


  • 2​008: Washington State Department of Transportation (WSDOT) completed Fairhaven to Slater Interstate 5 (I-5) Master Plan, which recommends a $40 million Single Point Urban Interchange (SPUI) at the West Bakerview/I-5 interchange. WSDOT and City agreed that funding was unlikely to ever materialize for this.
  • 2010-2011: WSDOT funds a multi-agency West Bakerview/I-5 Interchange Value Planning Study (VPS), which identified Option 1 low-cost short-term improvements and an Option 2 new northbound on-ramp, which would require an Interchange Justification Report (IJR) with WSDOT and the Federal Highway Administration (FHWA).
  • 2013: Option 1 was constructed by Bellingham in 2013 for $3.5 million with multiple funding partners (Whatcom County, Economic Development Investment Board, Port of Bellingham, Fred Meyer, and Transportation Improvement Board).
  • 2014: Bellingham City Council adopts the 2015-2020 Transportation Improvement Program (TIP) with the West Bakerview / Interstate 5 Interchange Improvements listed as unfunded TIP project 23. 
  • 2015: Bellingham contracts with WSDOT for $250,000 to lead the required IJR; the City of Bellingham successfully lobbied the State legislature to secure $10 million in “Connecting Washington” gas tax funds for West Bakerview / Interstate 5 Interchange Improvements.
  • 2015-2016: Multi-agency IJR meetings occurred every month; 17 alternatives were narrowed down to 5 alternatives for in-depth analysis of the best option to improve multimodal safety, mobility, and circulation while reducing traffic congestion at I-5 in support of economic development in northwestern Bellingham. 
  • 2016: A public Open House was held on October 25 from 7:00 – 9​:00pm at Alderwood Elementary School in northwest Bellingham and well- over 100 people attended.  The IJR process concluded in December with a unanimous multi-agency recommendation for a new northbound on-ramp on the east side of I-5.  The IJR received final signatures of approval from FHWA in June 2017 allowing project engineering to start.
  • 2018-2020: WSDOT design of new on-ramp completed, right-of-way acquisition completed, and construction bids being readied for advertisement in October 2020 with construction anticipated for Spring 2021, pending adequate construction funding.
