Halifax Road
The Halifax Road or Grand Communication Route was used by the British as an overland communication link between the British colonies of Nova Scotia, New Brunswick, Lower Canada (Quebec), and Upper Canada(Ontario) in the winter months when the St Lawerence River was frozen.
It was used as a mail route as well as a military avenue for British soldiers. It was first used in the transportation of soldiers during the War of 1812 when the 104th (New Brunswick) Regiment marched from Fredericton NB to Kingston in Upper Canada. It was a large contributor to the so called "Aroostook War" as the United States claimed a portion of it was in US territory. This road would be the key to the settlement of the Webster-Ashburton treaty of 1842.
This route was also used during the Canadian Rebellions and the Trent Affair to transport British soldiers to inland destinations in the winter months.
