Highway 174 has reopened between Trim Road and Cameron Street after a tanker truck rolled over on Wednesday night.

The two-vehicle incident happened at around 8 p.m. on Wednesday. The truck ended up in a ditch and a woman driving a four-door compact car had to be removed from the car by emergency responders.

The 21-year-old woman suffered head trauma and was taken to hospital in critical condition. The driver of the transport truck was also taken to hospital.

A hazardous materials truck was dispatched to the scene and determined that the transport truck's load, a sandy material, isn't dangerous. A crew sent by a Montreal company spent the night transferring the sandy material into another truck, said fire department spokesman Marc Messier.

About 100 litres of diesel fuel from a tank on the transport truck spilled into a culvert and then into the nearby Ottawa River, Messier said. Crews only noticed the fuel spill Thursday morning when a tow truck attempted to move the rolled over transport truck for the first time.

Water rescue crews have placed absorbent booms into the river to contain the spill, and a hazardous materials unit is cleaning up the fuel in the culvert, Messier said.

Cleaning up the diesel fuel could take several days.
