I-5 - Marine View Dr to SR 528 - Peak Use Shoulder Lane & I/C Improvements - Contractor resources

Project delivery:

WSDOT will manage project construction for the I-5 Marine View Drive to SR 528 Peak-Use Shoulder Lane 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.

Procurement schedule:

We anticipate hiring a contractor in the summer of 2020 and starting construction in 2021. Construction should take around two years. 

  • Request for Qualifications (RFQ): Spring 2020
