The SODO Busway, also referred to as the E-3 Busway, is a 1.5-mile-long (2.4 km)busway in the SoDo neighborhood of Seattle, Washington. It has four stops, including two that connect to Link Light Rail stations, and functions as an extension of the Downtown Seattle Transit Tunnel. The busway is served by ten bus routes—seven King County Metro routes from southern King County and three Sound Transit Express routes from Pierce County.
The busway begins at an intersection with S Spokane Street, which is split into a couplet underneath the elevated Spokane Street Viaduct. The entrance is located about two blocks away from ramps to Interstate 5, which most routes utilize to travel between Downtown Seattle and their southern terminal.
The busway follows the 5th Avenue S corridor, which was a railroad right of way that once ran to Union Station. Buses share the corridor with freight trains (between S Spokane Street and S Forest Street), Central Link light rail trains (between S Forest Street and the Downtown Seattle Transit Tunnel portal), and the SODO Trail (between S Forest Street and S Royal Brougham Way). The busway ends at the southern portal Downtown Seattle Transit Tunnel located underneath Seattle Boulevard S, where it is joined by ramps that carry buses from the I-90 express lanes, down into the tunnel.
Buses that serve surface streets in Downtown Seattle (instead of the transit tunnel) enter and exit the busway using S Royal Brougham Way and the bus only lanes on 4th Avenue S.
