Downtown Seattle Transit Tunnel goes rail only on March 23
As we hope you have heard by now, on Saturday, March 23, Link light rail will be the only service at Westlake, University Street, Pioneer Square and International District/Chinatown stations. All former tunnel bus routes will move to surface streets.
Though our region built the Downtown Seattle Transit Tunnel for buses back in 1990, they did so planning for an eventual full conversion to rail.
As Link light rail became a reality in 2009, the region still needed interim bus capacity until the Link system could grow, so our region became the only system in the world where buses and trains shared underground stations.
Why do this now? Two reasons:
The Washington State Convention Center expansion project will soon remove the northbound access point for buses at the former Convention Place Station.
Sound Transit needs to update the older downtown Seattle stations to prepare for expansion to Northgate in 2021 and the opening of the Blue Line to the Eastside in 2023.
