 Ironically , the first section of Highway 33 to be assumed as provincial highway is not part of the commemorated Loyalist Parkway . On July 9 , 1930 , the Department of Highways assumed the Trenton – Stirling Road as King 's Highway 33 , a distance of approximately 25 kilometres ( 16 mi ) . In July 1934 , as part of a depression @-@ relief effort , the Carrying Place Trail through Prince Edward County and the United Counties of Lennox and Addington was assumed as an extension of Highway 33 . ( The section between Trenton and Glenora was assumed on July 4 , 1934 , the section between Adolphustown and Kingston on July 11 . ) The provincially operated ferries , as the first to operate without a toll on the route , entered service after 1936 .
