North Link will be a continuation of the 5·1 km Westlake - Capitol Hill - University of Washington extension, which is scheduled to open in 2016.

Groundbreaking for North Link is planned for this summer, for opening in 2021. The 6·9 km mostly underground North Link will have stops at Brooklyn in the University District, Roosevelt and Northgate Mall.
