Marine View SR 529

Project delivery:

WSDOT will manage project construction for the I-5/NB Marine View Drive to SR 529 Corridor and Interchange Improvements project through a design-build contract. With design-build project delivery, we execute a single contract with one entity (the Design-Builder) for design and construction services. Please note, the preferred alternative selected by WSDOT in summer 2019 will build a fourth fixed lane that will be designated HOV.
