TORONTO, Ont. – A second body has been found in the Nith River after an 18-wheeler plunged off of Highway 401 west of Cambridge Tuesday afternoon.

The eastbound lanes of Highway 401 near Cambridge have now re-opened, but at least one lane will be closed again Wednesday morning as work resumes.

Crews initially planned to work overnight removing the trailer from the river, but work was instead postponed and will resume early Wednesday.

The incident happened at around 11:30 a.m. Tuesday in the eastbound lanes when a transport truck veered off the highway, smashing through a guard rail and ending up in the water below.

The trailer part of the truck was partially submerged in the river, while laptops and other electronics could be seen floating nearby.

The cab of the transport truck was completely submerged and it took emergency crews a significant amount of time to locate the two bodies.

The collision site is about 25 minutes west of Cambridge, just west of Trussler Road.

Police have not commented on the identity of the bodies except for saying that the driver was one of them, while a passenger in the truck was the second.

Anyone with information or who witnessed the crash is being asked to contact police or Crime Stoppers.
