Mudslide closes 403 near Hamilton

A water main break has caused a mudslide that is causing traffic havoc on Highway 403 near Hamilton Friday morning.

Ontario Provincial Police tweeted just before 8:30 a.m. that the 403 between Main Street East and York Boulevard is jammed because of trees and flooding on the highway blocking the eastbound lanes.

OPP Sgt. Kerry Schmidt told CBC Hamilton that a water main break on York Boulevard is causing the problem.

“The Mud is continuing to seep out there onto the highway,” he said. “It looks like the embankment is still collapsing.”

Schmidt said police are looking at a “full closure” of the eastbound lanes at least until the water is shut off and the mess is cleaned up.

Schmidt could not immediately say how long the closure would last. According to Hamilton police, the Toronto-bound ramp to the 403 is closed at King Street.

Friday morning's commute was already a slow one for many, as crews cleaned up a major accident at Trafalgar Road in Oakville involving a car and a transport truck.

The truck's bed was on its side for hours and was blocking lanes until just after 8 a.m.

Commuters took to Twitter Friday morning to vent their frustrations while sitting in traffic:
