The St Clair River corridor serves as the industrial and international backbone of this 1929 tactical map, showing the dense rail and ferry connections between Port Huron, Michigan, and Sarnia, Ontario. A complex web of transportation infrastructure is evident, including the Grand Trunk railroad lines and the notable Tunnel connecting the two nations beneath the riverbed. Along the western shore, the growth of Marysville and South Park reflects early 20th-century expansion, while smaller stops like Harts Sta and Bemer Road Sta indicate a landscape still tied to local rail service.
