*The COVID-19 crisis is greatly reducing the revenues Sound Transit relies on to expand our regional transit system. With greatly depleted revenues, Sound Transit will not be able to deliver many expansion projects on their original timelines unless we receive alternative revenue from federal or state sources. Through a process called realignment, the Sound Transit Board of Directors is working to determine which plans and timelines for voter-approved projects will need to change due to lower revenue projections.
