METEGHAN, N.S. -- A bridge over a busy provincial highway in southwestern Nova Scotia has been closed after it was struck by a truck towing an excavator.

The provincial Transportation Department says the Bonnie Road overpass near Meteghan, about 40 kilometres north of Yarmouth, suffered structural damage around 10 p.m. on Sunday.

The department says the truck struck it while driving on Highway 101 and the collision caused damage to several of the main steel girders on the overpass.

Inspectors examined the overpass Monday and said it will have to be closed for "a number of months" for repairs.

Andrew Preeper, a spokesman for the province, says the province is setting up a detour.

He says while there isn't a cost estimate, it is normal in this kind of case for the province to seek reimbursement for damages from the truck's owner.
