System expansion

Planning and building fast, reliable transit

New voter-approved Link light rail, Sounder train and ST Express bus rapid transit projects are underway. See how this new service can get you to your destination.

The Platform

As we prepare for 33 miles of new light rail extensions, critical maintenance and system upgrades will cause some 1 Line disruptions, including longer waits for trains and some bus shuttles temporarily replacing train service. 

Check out the latest pics from the newest station in Seattle's Central District!
