A bridge constructed over a tributary of the Good River in Alaska replaced an old, elevated culvert. It utilized $600,000 in funding from the Bipartisan Infrastructure Law, which was funneled through the National Fish Passage Program. Photo USFWS Ryan Hagerty
Picture of a culvert on a tributary to the Good River has become “perched” over time (1999 left; 2021 right). According to the U.S. Fish and Wildlife Service, fish have a hard time navigating the resultant low flow through the culvert and small/juvenile fish have difficulty jumping into the now-hanging pipe.
