The bridge is open! Visit the photos page for pictures from the official opening events.
Thank you to Kelly O'Connor for this great shot of the North approach paving work.
Bridge deck work continues, with all deck panels now placed and panel grouting complete. Reinforcing steel for the deck panel infills is complete, and 50% complete for the curbwork. Interior formwork is near completion, and exterior formwork is more than 50% complete. Curb concrete is one third poured, and concrete infills is one half complete.
Lock Up Devices (LUDs) are connected to the Pier 2 North pier head in preparation for truss connection. The asphalt plant has been mobilized and is being set up in preparation for paving.
It is expected the Bridge will be open for traffic in November.
Thank you to Phil Goulet for his picture from the early days of the Deh Cho Bridge construction. Phil will receive a Department of Transportation water bottle and be entered into a draw for a laptop bag.
