Metro Vancouver drivers who commute through the George Massey Tunnel may have their weekend travel impacted this weekend.

According to government contractor Mainroad Lower Mainland Contracting, there will be two overnight closures on Friday, Sept. 18, and Saturday, Sept. 19, for tunnel maintenance.

Mainroad announced the northbound lanes of Highway 99 will be closed at the Massey Tunnel on Friday from 9 p.m. to 6 a.m. the next day.

Then, on Saturday, the southbound lanes will be closed from 9 p.m. to 6 a.m. on Sunday.

Detour signs will be on site to direct traffic, with drivers being asked to use an alternative route like the Alex Fraser Bridge.

The overhaul of the George Massey Tunnel is slated to begin in 2027, with the new eight-lane, toll-free tunnel targeting an opening date of 2031.

“Highway 99 is a key connection for communities on both sides of the Fraser River and a vital trade route. Opened in 1959 as a vehicle-only crossing, the four-lane George Massey Tunnel no longer meets the region’s needs or modern seismic standards. Highway sections at both ends of the tunnel require upgrades to improve safety and traffic flow for vehicles, transit users, pedestrians and cyclists,” the B.C. government states.

B.C. Minister of Transportation and Transit Mike Farnworth provided a major update this summer on the new replacement George Massey Tunnel project.

The project will now carry a cost of $8.5 billion — more than double its previous cost figure of $4.15 billion, but below the range of $9 billion and $12 billion that has been floated by critics and others previously.

It was announced today that the Government of Canada will provide up to $3 billion in direct funding to build the new replacement crossing.

This falls under the new Canada-British Columbia Cooperative Prosperity Agreement, with the federal government offering to cover up to one-third of the cost of building the new tunnel.

In addition to this direct funding, there could also be low-interest federal loans and other borrowing capacities to help cover the provincial government’s total cost of building the project.
