1991 Map of Port Huron

About this map

The St Clair River serves as the international border between Port Huron, Michigan, and Sarnia, Ontario, in this detailed look at a bustling border crossing in the early 1990s. The landscape is defined by the heavy industrial and transportation infrastructure required for trade between the United States and Canada, notably the St Clair Tunnel and various sewage and industrial waste disposal facilities. In Port Huron, the residential fabric is dense with institutional landmarks like Mercy Hospital and St Stephen Ch, while the Canadian side features the distinct riverside settlements of Corunna and Froomfield. The map reveals the era's balance of industry and community, showing numerous schools such as Michigamme Sch and Chippewa Jr High Sch alongside the sprawling rail networks and shoreline waterworks that powered the regional economy.
