Drivers will have to pack their patience Tuesday as construction work has led to the closure of most westbound lanes on Highway 401.

In a video posted to social media, Middlesex County OPP Const. Jeff Hare says Highway 401 between Highbury Avenue and Wellington Road is currently reduced to one lane for construction work.

Hare says crews are painting lines on the newly paved road.

“You gotta be patient,” Hare said. “We know it’s gonna slow things down there.”

Hares cautions drivers to slow down well in advance of approaching the construction zone, and says the slow lane is the only lane currently open.

The westbound lanes will be closed for a few hours on Tuesday afternoon to facilitate the painting, and then the closure will transition over to the eastbound lanes.

“Safe travels, get to where you’re going safe as you can,” Hare said.
