Sound Transit will reduce light rail service to a single track through downtown Seattle, starting this weekend. The agency is warning travelers of longer wait times, crowded platforms, and packed trains.

The reduced service is part of the system’s expansion to the Eastside. It will prompt delays and closures for 10 weeks, starting on Jan. 4. What this means: Trains will arrive every 12 minutes, instead of the usual 6 minutes. This could add 30 minutes to commutes.

Bikes will not be allowed inside the Pioneer Square station. Bicyclists will have to get off at either the University Street or International District stations.

Light rail will shut down between the Capitol Hill and SoDo stations over the weekend. Free buses will be available to riders to cover the gap. The biggest change riders will experience is having to switch trains at the Pioneer Square station. A temporary, middle platform has been built so riders don’t have to go up and down two flights of stairs to change trains. Ron Lewis is Sound Transit’s Executive Director of Design, Engineering and Construction Management. He says that that trains will now be arriving every 12 minutes instead of every 6 minutes. That means wait times will lengthen and the agency told riders to add 30 minutes to their commute.

Bicycles will not be allowed in the Pioneer Square station for safety reasons, Lewis said, and bicyclists will have to get off at either the University Street or International District stations. This weekend will be especially tough as all light rail will shut down between the Capitol Hill and SoDo stations. Sound Transit says free buses will be available to riders and no fares will be charged north of Capitol Hill and south of SoDo. Light rail will shut down again the weekends of February 8 and March 14. Lewis said Sound Transit “ambassadors” will be at each stop during this time to help direct riders, including at SeaTac Airport to assist out-of-towners.
