The earthquake-proof underwater tunnel that costs 2.31bn and is just half a mile long | World | News [Video]

An earthquake-proof tunnel that covers a distance of just half a mile will cost Canada £2.31 billion.

The 2,625 ft eight-lane immersed tube tunnel, which works out at about £880,000 per foot, should be able to withstand earthquakes, water pressure and heavy traffic loads when it opens in 2030. 

Work on the mega-project is set to begin in 2026 to replace the ageing four-lane George Massey tunnel which connects Delta and Richmond in British Colombia, Cananda.

It’s hoped the toll-free tunnel could support economic development due to the improved flow of goods and people along highway 99, according to Shangeeta Snape, mobility managing director of Arcadis Canada which is putting together designs for the project.

The Fraser River Tunnel Project will have a dedicated transit lane in each direction to facilitate movement of goods, and a multi-use pathway for cyclists and pedestrians.
