The Danbury Local Protection Project is located along the Still River in Danbury, immediately downstream of the city’s central business district. It provides protection to 90 acres of industrial, commercial, and residential land.

Project construction began in June 1974 and ended in November 1976, costing $14.3 million. Upon completion, it was transferred to Danbury for operation and maintenance.

The project consists of 3,625 feet of concrete conduit and 2,695 feet of enlarged and realigned Still River channel. Work also required rebuilding four railroad bridges; constructing two highway bridges; and removing a privately owned bridge.
