UPDATE: All lanes are reopened.
Highway 401 Westbound in Cardinal remains closed after three transport trucks were involved in collisions earlier today.
OPP Sergeant Cynthia Savard says an initial collision happened last night when a transport truck went into the median. This morning, two other transport trucks collided. The highway is currently closed for the removal of the tractor trailers.
Savard says there were no injuries during the collisions. There is no time estimate for when the lanes will reopen and the investigation is ongoing.
