Boulders, some the size of engine blocks, came crashing down onto Highway 3 near Keremeos.
The front of a semi-truck trailer was hit by one of the rocks last night; luckily, the driver was not injured.
The slide closed the section of highway overnight, but it was re-opened the next morning.
The province’s Ministry of Transportation said warm temperatures and rain may have triggered this recent slide.
This is the same area where a major rock slide took place last January and closed the highway for nearly a week.
