Geography
In 1994, Ministry of Transportation Ontario constructed a truck arrester bed at the north entrance to the City of North Bay. Thibault Hill, with an elevation change of about 100 m on the eastbound Trans Canada Highway at the north entrance to the City is not an extremely steep or long hill: however, it has unique features that justified the choice of a truck arrester bed. It was hoped that the truck arrester bed would improve safety, as there have been several incidences (with one fatality) of trucks losing their brakes on the downgrade and failing to stop at traffic lights. The climate of North Bay is severe.
