In the coming years, the viaduct construction will mean changes for a number of bus routes in downtown Seattle, a few of which also serve Ballard. Metro Transit is asking for input via an online survey from riders in order to best reroute during the tunnel project.
From Metro:
Metro is planning ahead on how buses will be routed through downtown Seattle in the long-term and during construction once the SR 99 tunnel project is complete and the city of Seattle begins works on the Central Waterfront project. It is starting by soliciting feedback from the public via an online survey, and would particularly like to hear from current riders of routes: 15, 15X, 18, 18X, 21X, 54, 54X, 55, 56X, 113, 120, 121, 122, and 125.
Survey respondents will help Metro look at potential pathways to connect transit from south of downtown along Alaskan Way to the Third Avenue transit spine in the Central Business District. Two possible pathways are Columbia Street, or a combination of Main and Washington streets.
