Trains will run as usual between SODO-Angle Lake and Capitol Hill-UW, with three-car trains every 10 minutes during most hours of the day. Free bus shuttles will run every 7 minutes in groups of two buses at a time, serving SODO, Stadium, International District/Chinatown, Pioneer Square, University Street, Westlake and Capitol Hill.
Plan accordingly. Weekend closures will happen again from Oct 25-28 and Nov 8-11. This is all in preparation for Connect 2020, the project to tie East Link (a.k.a. the Blue Line) in with the downtown tunnel.
WSDOT is also closing the westbound lanes of the SR 520 Floating Bridge over the weekend to prepare for several years of Montlake construction. Bus routes using the bridge will detour via Interstate 90 and will skip some stops, so check the Metro Alerts page. Eastbound service will use all normal stops, but may be affected because of the longer trip times.
