Rhode Island Navigation Projects

The Corps has completed 18 navigation projects in Rhode Island. These projects have improved rivers, bays, coves, and harbors that are used by commercial interests, fishermen, and the many recreational boaters that benefit from Rhode Island's intricate and fascinating coastline and its inland waterways. Initial work on many of the projects dates back to the 19th century. However, most of the navigation work in Rhode Island's waterways has been constructed by the Corps within the past 50 years, at an aggregate cost of $33.3 million. Below are the Corps' navigation projects in Rhode Island.
