No students were injured after a school bus and a transport truck collided on Highway 102 south in Lower Sackville.

A transport truck cut across traffic and drove off the Highway 101 overpass and landed on Highway 102 on Thursday afternoon, according to an eye witness.

A school bus hit the transport truck, but RCMP Cl. Guillaume Tremblay says there were no reported injuries.

Highway 101 is reduced to one lane and Highway 102 near exit 4B, an interchange where  Lower Sackville meets Bedford, is closed.

Tremblay says it will likely be closed for several hours because trucks require heavy machinery to move out of the road.

The investigation continues.
