Press release:

Link light rail will resume its normal nighttime operating schedule beginning Monday, June 10.

Sound Transit contractors have completed installing a new sound wall along the light rail tracks near the Duwamish River in Tukwila. The work forced delays through the area and was originally anticipated to last through July.

Now that the work is finished early, Link light rail trains will again run every ten minutes from 9 – 10 p.m. and every 15 minutes from 10 p.m. – 1 a.m. on weeknights.
