I-5 Northbound Marine View Drive to SR 529 Corridor and Interchange Improvements
Transportation Funding: $122 Million
This Washington State Department of Transportation (WSDOT) project is scheduled to start design in spring of 2022 with construction beginning in 2023 and tentative completion in 2024. The project received funding through the 2015 Connecting Washington Transportation package.
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.
