1939 Map of Port Huron

About this map

The confluence of the Black River and the St Clair River defines this 1930s landscape at the international border. The industrial and transit identity of Port Huron is evident in the dense network of rail lines, including the Grand Trunk Western and the Port Huron and Detroit, which facilitated cross-border trade through the rail tunnel near Sarnia. South of the city center, Marysville appears as a burgeoning industrial corridor along the riverfront, while rural schoolhouses like Allendale Sch and Mellore Sch mark the residential fringes. The map illustrates the strategic importance of the waterway, showing Stag Island and the transition from the city grid to the outlying townships. Detailed road labeling, from Gratiot Ave to Beach Rd, provides a clear view of the region's pre-war infrastructure and its connection to neighboring Ontario communities like Point Edward.
