The Northgate Link Extension is a light rail project in Seattle, Washington, designed to expand the Link light rail system. It connects the existing line from University of Washington to the new Northgate Station, enhancing public transportation access for residents and visitors in the area. This extension includes two additional stations: Roosevelt Station and Northgate Station. It aims to improve mobility, reduce traffic congestion, and provide a reliable transit option for commuters traveling to and from the Northgate neighborhood and surrounding regions. The project is part of a broader effort to expand the Sound Transit network.
