Provincial Police say one person is dead and three others are injured following a multi-vehicle collision on Highway 401 near Woodstock.

Police say the initial collision occurred in the westbound lanes of the 401 right infront of the en-route service centre near Woodstock. Multiple vehicles were involved in that collision which lead to a secondary collision in the eastbound lanes where one person was struck and killed.

Police are investigating how that person came to be in the eastbound lanes, but the two collisions are said to be related.

As a result the 401 is closed eastbound at Folden’s Line and westbound at Sweaburg Road.

Three other people were taken to a local hospital with non-life threatening injuries. The highway is expected to be closed well into the afternoon.
