Construction on all three stations of Seattle's Sound Transit's Northgate Link Extension is now substantially complete, Sound Transit officials announced yesterday.
The elevated station at Northgate was the last to see construction substantially completed. Construction at the UDistrict station was substantially completed last summer, and construction of the Roosevelt Station was substantially completed earlier last year.
Light-rail test trains began operating on the new elevated track last month to test the overhead electrical power system throughout the Northgate line. Testing will continue for several months, mostly during morning hours. Work on the project is now focused on completing systems work, which includes electrical and communications systems.
When finished, the 4.3-mile regional light-rail extension will offer riders traffic-free travel between Northgate and downtown Seattle in 14 minutes.
Sound Transit is simultaneously working to extend light rail north, south, east and west. Northgate Link will be followed in 2023 by the opening of service to Mercer Island, Bellevue and Redmond's Overlake community. Additional extensions to Shoreline, Mountlake Terrace, Lynnwood, Kent/Des Moines, Federal Way and downtown Redmond are planned in 2024.
