Cincinnati-area public transit advocates are suing federal and state officials over the environmental review of the $3.6-billion Brent Spence Bridge Corridor Project between Ohio and Kentucky, saying the Federal Highway Administration ignored “significant impacts on the human environment.”

The group, Devou Good Project Inc., is asking a federal judge to declare that the agencies and officials violated the National Environmental Policy Act by overlooking health and environmental impacts when it issued a finding of no significant impact (FONSI) instead of preparing a full environmental impact statement. They also want the judge to vacate the finding and any agreements authorizing the use of federal funding for the project, and to issue injunctions barring any work on the project until the issues have been addressed.
