North Corridor HCT (High Capacity Transit) Project

Extending Central Link light rail from Northgate to Lynnwood Transit Center

This project was approved by public vote as part the Sound Transit 2 ballot measure on Nov. 4, 2008.

The project will construct an extension of the Central Link light rail system extending approximately 8.2 miles from Northgate to Lynnwood Transit Center. For cost estimation purposes, the alignment is assumed to be entirely aerial primarily along I-5. The final alignment and station locations will be determined through project level design and environmental review.

Project elements include:

• Link LRT guideway, track and systems extended approximately 8.2 miles north from Northgate Station to Lynnwood Transit Center
• Alignment entirely aerial primarily along I-5
• After leaving Northgate Station, the alignment would continue along the east side of I-5 to North of SW 220th St, where it would cross over I-5 to the West side
• Four new stations at NE 145th Street, NE 185th Street, 236th Street, and Lynnwood Transit Center (terminal station), all sized to accommodate 4-car trains
• 500 structured parking spaces at NE 145th Street, NE 185th Street, and Lynnwood Transit Center (in addition to existing parking)
• Pedestrian bridge across 44th Ave W. from Lynnwood Transit Center station
• Rebuild sound walls as necessary
• 1 percent for art per ST policy
• One track crossover at each station

Estimated Cost (2007$): $1,174 - $1,381 million
