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

This is the traffic westbound on the St. Albert Trail off-ramp on the Yellowhead. Cars are using it as a detour to get back onto the freeway. AVOID THE AREA. Traffic backed up closer to around 97 street. @ctvedmonton #yeg #yegtraffic https://t.co/oaiayLDioU… pic.twitter.com/eTV6QdcnJg — Nahreman Issa (@NahremanIssaCTV) July 18, 2019

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.
