Police say at least one person died following a multi-vehicle crash on Highway 1 in Chilliwack Monday.

The collision occurred in the westbound lanes of the highway near Vedder Road just before 5 p.m.

Aerial footage from the scene showed that at least three vehicles were involved in the incident, including a white SUV that somehow ended up on top of a smaller car. A pickup truck was also involved in the pileup.

Air ambulances were sent to the scene, but it’s unclear how many other people were hurt.

Drive BC warned commuters to expect heavy delays in both directions through the area. Westbound traffic was rerouted and officials urged drivers to proceed with caution.
