Update 2:25 p.m. Saturday: The eastbound lanes of the highway have reopened.
CORNWALL – A crash in the eastbound lanes of Highway 401 has closed a section of the highway between McConnell Avenue and Boundary Road.
The crash, which O.P.P. posted about on its Twitter account around 9:30 a.m., appeared to involve a single vehicle, a white Hyundai sedan, that had made contact with the end of a guardrail along the median.
The car had spun around and was on the shoulder of the eastbound lanes, facing west. The end of the guardrail was a hunk of twisted metal.

A homeowner along South Service Road, which runs parallel to Highway 401 on the north side, said he heard a loud pop just before the crash.
Around 12:20 p.m., O.P.P. investigators were laying evidence markers between the end of the guardrail and the vehicle about 500 feet down the highway.
Tweets from employees with Cornwall-SDG Paramedic Services show one person had been treated on scene and that person was taken by Ornge air ambulance.

Their identity and their condition is not known.
A call by Cornwall Newswatch to East Region O.P.P. was not immediately returned.
It’s not known how long the highway will be closed. Westbound traffic is unaffected.
