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.
It starts at a junction with Route 104 between Farnham and Sainte-Brigide-d'Iberville, next to a training facility of the Canadian Forces and runs north toward a parclo interchange with Autoroute 10 after which it crosses the Rivière du Sud-Ouest which it follows for a few kilometers until its headwaters on Yamaska River.
