Connecticut Navigation Projects

The Corps has completed navigation projects at 28 different sites in Connecticut. These sites include rivers, bays, coves, and harbors that are used by commercial interests, fishermen, and the many recreational boaters that enjoy the intricate and fascinating Connecticut coastline. Initial work on many of the projects dates back to the 19th century. However, much of the navigational work in today's waterways has been constructed by the Corps within the past 50 years, costing an aggregate total of $20 million. Below are the Corps' navigation projects in Connecticut.
