British Columbia's transportation minister says 130 kilometres of highway that was severely damaged by flooding two years ago is now more resilient to extreme weather.
Rob Fleming says the stretch of the Coquihalla Highway, or Highway 5, between Hope and Merritt, B.C., is an example of a "new normal" for how infrastructure needs to be built.
In 2021, road crews achieved the impossible by re-opening the Coquihalla just 35 days after it was destroyed by an atmospheric river.

Today, the full permanent rebuild of the highway is complete, with new climate-resilient bridges that will keep people and goods moving safely. pic.twitter.com/zCwmCzYVTA
A series of atmospheric rivers in November 2021 triggered mudslides and washed out highways and bridges that blocked almost every route between B.C.'s Lower Mainland and the Interior.
Fleming says the cost to repair the damage caused to Highways 1, 5 and 8 is somewhere between $1 billion and $1.5 billion, but 70 to 90 per cent of that is expected to be covered by the federal government's disaster assistance program.
It’s been two years since the atmospheric river that damaged more than 20 sites along 130 kilometres of the Coquihalla.

Jennifer Fraser, executive project director for the highway reinstatement program, says six bridges on the Coquihalla were replaced over 17 months.
She says some bridges have been made longer to allow more water to pass underneath, and crews strategically placed rocks and vegetation to help fight erosion.
Fraser says the bridges are also on stronger supports, with the longest pile being driven 65 metres into the ground.
Fleming says one of B.C.'s most important trade corridors is now better able to resist future climate events.
"Our infrastructure has to be able to withstand extreme weather conditions. This is the new normal for the safety of our residents and the movement of goods throughout the province. This is an important infrastructure priority for British Columbia."
