 The section of I @-@ 87 between exits 38 and 39 crosses a marshy area surrounding Dead Creek , a stream feeding into nearby Cumberland Bay . Access to the bay shore is provided off to the northeast by exit 39 , a modified cloverleaf interchange for NY 314 . Continuing away from the junction , I @-@ 87 comes within 1 mile ( 1 @.@ 6 km ) of Lake Champlain as it follows US 9 away from Plattsburgh and northward across open , rolling fields in the towns of Beekmantown and Chazy . Outside of the hamlet of Chazy , the Northway begins to run across a series of wetlands along the west side of US 9 . The marshy terrain follows I @-@ 87 into the town of Champlain , where I @-@ 87 encounters the northernmost community along its course , the village of Champlain . I @-@ 87 veers slightly westward to avoid the village , and in doing so it meets US 11 at exit 42 , a diamond interchange just west of the village limits .
