Massachusetts Navigation Projects

The Corps has completed 50 navigation projects in Massachusetts. These projects have improved rivers, bays, coves, and harbors that are used by commercial interests and the many recreational boaters that benefit from the intricate and fascinating Massachusetts coastline. Work on many of the projects dates back to the early 19th century. However, much of the navigational work in today's waterways has been constructed by the Corps within the past 50 years, costing about $124 million. Below are the Corps' navigation projects in Massachusetts.
