A section of the Yellowhead is closed at St. Albert Trail because of a sinkhole.

Flooding caused heaves in the westbound lane and holes in the pavement.

Earlier in the evening, six people had to be rescued from vehicles after flooding on the Yellowhead.

City crews and police tell CTV News that an engineer will need to survey the damage before road repairs can start.

Officials estimate the closure will last several days.

The eastbound lanes are open.
