The interchange improvements and high occupancy vehicle (HOV) lane will be built using a design-build contract. Using this type of contract, WSDOT executes one contract with a single firm that is responsible for finishing design work and then building the project.
“Atkinson Construction submitted the best value proposal for an improved interchange and extending the northbound HOV lane,” said Amir Rasaie, WSDOT Assistant Regional Administrator for project design and development. “We look forward to working with them to build this project.”
“This work will improve mobility for highway users, ease congestion, and provide more access to and from Marysville,” said Atkinson Senior Project Manager Reggie Wageman. “We intend to build a project that meets the needs of the community, minimizes effects on travelers, and looks for efficiencies in design and construction to provide the best value for taxpayers.”
The improvements include:
- A northbound ramp from I-5 to State Route 529
- A ramp from SR 529 to southbound I-5
- Extending the existing northbound HOV lane from its existing end near US 2 in Everett to south of SR 529 in Marysville
Construction on the $123.1-million project is scheduled to begin in late 2022 with the improved interchange and HOV lane scheduled to open in 2025.
