From Bedford at the intersection of Trunk 2, Trunk 7 leaves to the southeast along the eastern shore of the Bedford Basin, then climbs Magazine Hill next to the Canadian Forces Magazine and enters Dartmouth on Windmill Road. Through Downtown Dartmouth, it is known as Alderney Drive, which turns into Prince Albert Road past Sullivan's Pond as it runs along the shore of Lake Banook. At Grahams Grove Park, Trunk 7 continues through the Micmac Parclo, on to Main Street, past Highway 111 and to the community of Westphal, bypassing most of Cole Harbour to the south.
