Tunnelling completed on Northgate Link LRT
8 September 2016US - The TBM finishing the last drive on Seattle’s Northgate Link LRT project has reached University of Washington station on September 2.
Sound Transit’s tunnelling contractor, the Jay Dee/Coluccio/Michels (JCM) joint venture, finished its remaining Northgate Link tunnel drive, of six, with TBM #1, the transit authority announced April 29.
JCM had previously used refurbished TBM #1, manufactured by Hitachi Zosen, to mine the 230 tunnel contract for Seattle's University Link light rail project. The project’s second TBM was dismantled this summer.
