Sound Transit is making substantial progress on the Northgate Link and South Link extensions. This week, two key milestones were reached with tunneling work and the placement of final elevated guideway segments.
Pamela, one of two tunnel boring machines (TBMs) mining the underground Northgate Link extension, broke through to the Roosevelt Station Station pit. Her arrival marks the second TBM to reach the station this year. Pamela was initially launched in November from the Maple Leaf Portal near Northgate Mall. Since then, she has traveled southward for the first 1.5 miles of her 3.4 mile trip to University of Washington Station. Pamela will take a temporary break at the Roosevelt Station site for repairs and refurbishment until being relaunched. The TBM will continue onward to the next station pit site located in the University District.
