Few Michigan towns list much on the Register (a typical Michigan town has 0.0 per 10,000 residents, the U.S. 2.4), so Woodbridge Township’s 0.0 sits below most of its state (32% of Michigan towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.

What stands out about Woodbridge Township’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Woodbridge Township was organized in 1840 from the southernmost section of the then-larger Fayette Township. Woodbridge Township extended south to the state border with Ohio until Amboy Township was created from the southernmost section of Woodbridge Township in 1850.
The current Woodbridge Township Hall in the community of Frontier was built in 1855 after the township board approved $250 for its construction and $10 for the land for the building. The structure was completed in 1856 and received several additions in later years. In 1975, the Michigan Townships Association verified Woodbridge Township Hall as the oldest operational township hall in the state.
