Thornapple Township maintains miles of paved roads and gravel roads. There are also many private roads throughout the township. Highway (M-37) is managed by the Michigan Department of Transportation.

Township roads are maintained by the Barry County Road Commission (269-945-3449) with the township paying for dust control and upkeep on gravel roads and repairs on paved roads, including line painting on paved roadways. Road upkeep and repairs are currently paid for through the general fund at Thornapple Township.

A new bridge and road was opened in July of 2011 that serves the community with an all-weather connection to 131 expressway to the west of the township.  This second bridge over the Thornapple River is located on Finkbeiner Road on the northern edge of Middleville.

Please contact the Township Supervisor during regular business hours with any questions or concerns.
