Multiple settlements comprise present-day Saginaw. On the west side of the river the first settlement around what had been Fort Saginaw developed into Saginaw, which was incorporated as a city in 1857, containing the seat of the Saginaw County government. On the east side of the river a parallel settlement, East Saginaw, developed which was incorporated first as a village in 1855, and then as a city in 1859. Also south of East Saginaw, on the east bank of the river, the village of Salina formed. Salina's name relates to the brine that led to a growing industry of salt production in the area. Both Saginaw and East Saginaw quickly became a hub for railroad transportation in addition to ships on the Saginaw River.
