TBM Parts Arrive for BC’s Broadway Subway Project

All the component parts for the tunnel boring machines that will dig the twin tunnels for the Broadway subway project have arrived in British Columbia.

The second and final shipment of high-tech equipment left Germany on April 6, 2022, and arrived at Fraser Surrey Docks on May 20, 2022, after sailing to New York, through the Panama Canal and up the west coast of North America. The first shipment of parts arrived in B.C. on April 15, 2022.

The parts are being transported to the site of the future Great Northern Way-Emily Carr Station, where they will be assembled in preparation for launch. People who pass by the staging area near Great Northern Way at Thornton Street in the coming weeks may notice the large cranes that will be used to move the machine components.

Once assembled, the two 6-m wide machines will be launched separately from the Great Northern Way-Emily Carr Station and tunnel to their removal point at Cypress Street, just east of the future Arbutus Station.

The tunnel boring machines will be named in the coming weeks, and a ceremony later this summer will mark the official start of tunneling, which is expected to take approximately one year.

Manufactured by Herrenknecht, the tunnel boring machines are custom-built to unique specifications for the type of construction as well as the underground conditions between Great Northern Way and Arbutus.

The 5.7-km extension to the Millennium Line is due to open in 2025.
