LONDON, ONT. -- Weather conditions made travel difficult on portions of the Highway 401 corridor Thursday evening.

Road conditions in many locations across southern Ontario were becoming treacherous into Christmas Eve night.

A drop in temperature, combined with rain and wet snow falling through the day left many highways very slick.

The eastbound lanes of the 401 just east of London had to be temporarily shut down.

OPP were reporting numerous accidents in the area with cars and trucks skidding on black ice.
