Previously identified preferred interim pathway during the Viaduct Demolition. The use of this reroute is contingent on the
schedules of the Alaskan Way Viaduct Demolition and City Center Connector projects, which are subject to change.
Note: This is our currently preferred pathway, but ongoing project coordination is needed to ensure it is successful.
Metro is working with WSDOT and SDOT to identify and generate possible alternative interim pathways, should they be
necessary.

For use during the approximately one-month period before the deep bore tunnel (and the Dearborn exit) opens.
Note: Lander Street is under construction through December 2019 and cannot be used to cross between 1st Ave S and
4th Ave S in SODO. We propose using Edgar Martinez Drive, as it is used as part of the proposed Lander Street construction detour for Routes 21, 37, 116, 118, and 119. Additional game-day detours may be needed when Edgar Martinez is
not usable; Holgate Street may be used to cross between 1st Ave S and 4th Ave S at this time.
