British Columbia’s Ministry of Transportation and Infrastructure has issued an RFQ to replace the ageing George Massey Tunnel with a new eight-lane, toll-free immersed tube tunnel on Highway 99 in Canada.

The project is in the environmental assessment process. Construction of a new five-lane Steveston Interchange and corridor improvements are already underway. The new crossing will be an eight-lane immersed tube tunnel with three general-purpose travel lanes and one dedicated transit lane in each direction. It will include bike and pedestrian crossings. The project also involves replacing the Deas Slough Bridge and adding a southbound general-purpose lane on Highway 99. These improvements will enable smoother travel at 80 km/h compared to the current average of 30 km/h.

A recently opened transit bus connection between Bridgeport Road and southbound Highway 99 is reducing travel time for transit users. Construction is currently underway for new bus-on-shoulder lanes south of the tunnel, which will further enhance travel times and improve the reliability of transit in the corridor. The estimated cost of the immersed tube tunnel for the George Massey Crossing project is approximately US$4.15 billion.
