SR 520 & AWV contracting opportunities

WSDOT held a virtual meeting for contractors on March 4 regarding contracting opportunities with two design-bid-build projects: the AWV South Access Surface Street Connections Project and the SR 520/I-5 Express Lanes Connection Project. This meeting was open to interested contractors of all sizes, from large primes to smaller minority-, veteran-, and women-owned businesses. Construction for both projects is slated to begin in spring or summer 2021. If you have questions, contact Regina Glenn, WSDOT Megaprograms Diversity and Inclusion Manager, at

Needs & benefits

This project completes final roadway work around the south portal of the SR 99 Tunnel, and builds new pedestrian and bicycle amenities that connect Seattle’s stadiums with the waterfront. The work includes paving portions of First Avenue South and South Dearborn Street, and turning Railroad Way South into a pedestrian plaza that links Seattle's stadiums with the central waterfront. Much of this work could not be completed previously due to SR 99 Tunnel and Alaskan Way Viaduct Demolition work.
