I-5 Northbound Marine View Drive to SR 529 Corridor and Interchange Improvements
Transportation Funding: $84 Million
A Washington State Department of Transportation project scheduled to be advertised in June of 2021 with construction beginning in 2022 and tentative completion in 2024. This project was fully funded in the 2015 Connecting Washington Transportation package with $50M for the Interchange Improvements and $34M for the I-5 Northbound Corridor Improvements.
The interchange improvements will complete the current half at I-5 and SR 529 interchange by constructing a new I-5 northbound off-ramp to SR 529 and a new southbound on-ramp from SR 529 to I-5. This project will reduce congestion at the interchange of I-5 and SR 528, which was identified by WSDOT as a high-accident location. The interchange improvements will allow traffic to avoid at-grade crossings with the BNSF mainline, which causes significant delays to the surrounding road system. The City completed preliminary design, started environmental review and obtained federal approval of the Interchange Justification Report to move the project forward.
The I-5 Northbound Corridor Improvements will provide a peak use hard shoulder lane between Marine View Drive in Everett and SR 529 in Marysville.
