At the international border crossing between Canada, the U.S. and the Ak-wesasne Mohawk Community on Cornwall Island in eastern Ontario, the North Channel Bridge Replacement -Three Nations Crossing replaces an existing high level bridge. The existing bridge - now being demolished - dates from 1962 and had reached the end of its serviceable design life. Morrison Hershfield was retained by the Federal Bridge Corporation Limited (FBCL) to provide consulting engineering services for the construction phase of the new low-level bridge. The new bridge is adjacent to the old one, approximately 17 metres apart.
