The City of Seattle City Council passed Ordinance CB 121003 on July 15, 2025, authorizing the Director of the Seattle Department of Transportation to execute Amendment No. 5 to the "Agreement between the City of Seattle and Sound Transit for Grant of Non-Exclusive Use of a Light Rail Transit Way as related to the Link Light Rail Transit Project." This amendment primarily reflects the approved alignment and light rail transit facilities for the West Seattle Link Extension, a component of the voter-approved Sound Transit 3 (ST3) plan. The ordinance also ratifies and confirms certain prior acts related to the transit way agreement, which has been amended multiple times since its initial execution in July 2000. The West Seattle Link Extension is part of a larger high-capacity regional transit system, including various light rail lines such as Central Link, University Link, Northgate Link Extension, Lynnwood Link Extension, and East Link. The decision enables Sound Transit to proceed with the West Seattle Link project by officially incorporating its alignment and facilities into the existing multi-party agreement.
