A crash on Highway 417 that caused an overhead sign to collapse onto a tractor trailer and several lanes of the highway caused significant traffic delays Monday night.

It happened at about 6:45 p.m., just before the exit at Pinecrest and Greenbank roads, when a car and a tractor trailer collided, Ontario Provincial Police said.

The tractor trailer slammed against a concrete barrier and struckĀ the pole holding up the overhead sign.

Nobody was hurt.

All eastbound lanes of the highway were closed at Richmond Road but the highway was reopened early Tuesday.
