An influx of federal funding is allowing the completion of preconstruction engineering and design work and construction of the initial phase of the Brandon Road Interbasin Project, with the first project contract expected to be awarded in 2024 as long as partnering states are able to provide the matching funds. The project, on the Des Plaines River near Joliet, Ill., includes a complex, layered barrier to prevent the spread of invasive carp and other nuisance aquatic species from the river into the Great Lakes. It consists of an engineered channel with a flushing lock, an air bubble curtain and an acoustic deterrent, all designed to work in tandem with an electric barrier in place in the Chicago Sanitary and Ship Canal in Romeoville, Ill., southwest of Chicago. The total cost for the project is expected to be at least $858 million, with an expectation that the cost may rise over time. Brandon Road Lock and Dam has been identified previously as a key choke-point where Asian carp must be stopped. |
