Bridgeport is an unincorporated community and census-designated place (CDP) in Saginaw County in the U.S. state of Michigan.

As an unincorporated community, Bridgeport has no legal autonomy of its own but does have its own post office with the 48722 ZIP Code.

[5][6] The settlement was first known as Cass Bend due to a sharp bend along the Cass River, and a post office named Bridgeport began operating here on October 12, 1836 in the Michigan Territory.

The name Bridgeport was derived from the numerous bridges that crossed the river at this point.

The township itself also had a post office named Bridgeport Centre, which began operating on August 1, 1851.

[1] The community is located approximately halfway between the cities of Saginaw to the northwest and Frankenmuth to the east.
