SR 520 Bridge Program: Contracting and Job Information

What is WSDOT's contracting process?

Contractors hired by WSDOT complete construction projects and hire administrative and field staff to work on those projects.

The selected contractors will be responsible for securing vendors and sub-contractors, and assembling their workforce. WSDOT will work with contractors to ensure that notification is provided to all potential parties, and have added contact information to this list of interested parties. 

To stay in touch and learn more about contracts as they become available, you can:

WSDOT advertises projects on the Contract Ad and Award website. At this website, contractors can view projects that are available for bid, learn about pre-qualifications, and stay up-to-date with contractor bulletins.

Apprenticeship requirements

Design-build teams will comply with an apprentice utilization requirement. The goal is that 15 percent of project labor hours will be performed by apprentices. The apprenticeship program provides on-the-job training and supportive services to assist contractors with recruitment and placement of minorities and women, as well as to provide advocacy and support for individual apprentices/trainees participating in the program.

Commitment to Disadvantaged Business Enterprises

WSDOT strives to create equal access and make opportunities available for Disadvantaged Business Enterprises (DBEs) on public works and other transportation-related projects.

Individual DBE goals are established for each federally funded SR 520 project based on the opportunities available and funding sources. WSDOT is committed to ensuring DBE firms are afforded equal access and opportunities consistent with DBE programs.

There are multiple resources available for DBE firms. More information about these services is available on WSDOT’s Disadvantaged Minority/Women's Business Enterprise Program web page or WSDOT’s Opportunities for Small Businesses web page

Future I-5 to Medina project construction

As identified in the I-5 to Medina project final EIS, the next construction phase of the I-5 to Medina: Bridge Replacement and HOV Project is construction of the West Approach area, connecting the new floating bridge to Montlake Boulevard. View a handout for more details of our plan to fund future work west of the floating bridge.

On March 23, 2012, Governor Gregoire signed Engrossed House Bill 2814, which allowed WSDOT to continue with SR 520 floating bridge construction. EHB 2814 also prohibits WSDOT from beginning construction on project elements west of the floating bridge until after June 30, 2014 unless "the legislature has authorized the imposition of tolls on the I-90 floating bridge and/or other funding sufficient to complete construction of the state route number 520 bridge replacement and HOV program."
