The Work

Drill and blast across five contracts on the twinning of the Trans-Canada Highway between Thunder Bay and Nipigon — cutting rock for new lanes with traffic running alongside.

Highway 11/17 is the Trans-Canada between Thunder Bay and Nipigon. Twinning it means cutting new lanes through the rock along the north shore of Lake Superior while the existing lanes stay open to traffic.

We have drilled and blasted on five contracts along the corridor since 2019 — Red Rock, Dorion, Hurkett, Pearl and Shuniah.

The photographs here are from the Pearl section: drills working the cut metres from passing traffic, production benches through the winter, and finished rock walls beside the new alignment.

Dartmouth Shopping Centre — Rock Anchors

Grouted rock anchors holding the rock walls of a commercial redevelopment excavation, installed row by row to the engineer's sequence, plus hollow-bar anchors pumped full of grout where the ground was too broken to hold a hole.
