WATERWAY AND LOCATION: The project would affect waters of the United States and navigable waters of the United States associated with the Illinois River and Curry Lake. The project/review area is located on US Route 67 over Illinois River in Beardstown, Illinois, in 15 Section, 18 Township, 12 Range; at Latitude 40.01055 and Longitude - 90.44349; in Beardstown, Cass and Schuyler County, Illinois.
EXISTING CONDITIONS: Existing conditions include a deteriorating bridge along Hwy 67 over the Illinois River that provides vehicle transportation between Jacksonville and Macomb, Illinois.
PROJECT PURPOSE: The purpose of the Proposed Action is to provide a transportation facility between Jacksonville and Macomb, Illinois that provides improved transportation continuity, enhanced economic stability and development, upgraded rural access, and improved travel efficiency while connecting the project area to other major transportation systems and communities in western Illinois. One of the major goals of the Illinois transportation system is to enhance the state’s economic advantage, expand economic bases in urban and rural areas, and retain existing economic bases and employment. A system of new and improved roadway facilities that link major economic markets is planned to strengthen the regional and statewide economic future. The Beardstown Bridge removal and replacement is one component of the larger U.S. 67 improvement project, which is part of a statewide plan to improve regional transportation continuity and enhance the linkage of west central Illinois to major economic markets. This improvement will connect sections of highway to the north and south that are currently either under construction or are in the planning phase.
Basic: Replace an aging bridge over the Illinois River
Overall: Increase vehicular safety along Hwy 67
