At Fredericton a controlled-access 4-lane section was built around the city, and the highway crossed the Saint John River on the Princess Margaret Bridge to the east bank just south of the central business district. Following the river's east bank just metres above its water level (frequently flooded in spring freshets), the route continued south to Jemseg where the highway turned east along the southeast shore of Grand Lake to Youngs Cove Road where the highway turned south to Coles Island and on to Sussex.
