The Ipswich Mills Dam is a historic structure that spans the Ipswich River in Ipswich. It was built in 1908 to provide power for the nearby mills, but it was decommissioned in the 1930s and sold to the town in 1982. The dam has significant ecological impacts on the river, as it blocks the migration of fish and alters the natural flow and water quality. The town is considering removing the dam to restore the river's health and habitat, as well as to create a freshwater tidal zone that is rare in Massachusetts. The dam removal project has been studied for several years and has received support from various partners and stakeholders.

The Ipswich Mills features a small walking bridge above the Ipswich river. The bridge is located between MA-1A and Union Street; it is also only a short distance from the Ipswich trail station.
