If you’ve driven north on Highway 99 towards the George Massey Tunnel lately, you may have noticed a crane working on Deas Island.
Crews were collecting geotechnical data as part of the George Massey Tunnel Replacement Project. The crane was equipped with a large pile driver, which pounded five piles into the ground to determine the maximum load a single pile can hold in that particular soil.
The information will be provided to designers bidding on the contract to build the new bridge to replace the tunnel. The new bridge will be built to modern seismic standards and improve highway safety, reduce greenhouse gas emissions from unnecessary idling, and save rush-hour commuters up to 30 minutes a day. When completed, it will be the largest cable-stayed bridge in North America.
Watch (and hear) the force needed to drive these piles 60 metres into the ground. It’s pretty amazing.
