How New Brunswick sizes up a heavy load
The New Brunswick Department of Transportation and Infrastructure issues special permits for oversize and overweight loads, as seven day single trip permits or for three months or one year. New Brunswick shares harmonized oversize permit conditions with Nova Scotia, Prince Edward Island and Newfoundland and Labrador. Sizes are metric, so every number here has feet and inches added. These are the rules we plan New Brunswick loads with, from the special permits page, the Conditions for Oversize Permits, Regulation 2001-67 and the Atlantic harmonized conditions.
