The Charles W. Dean Bridge, known before 1999 as the Great River Bridge, is a planned cable-stayed bridge to carry Interstate 69 and U.S. Route 278 across the Mississippi River between Arkansas City, Arkansas and Benoit, Mississippi. The Arkansas State Highway and Transportation Department began land acquisition for the project in October 2006, but no funding has been provided for construction. Preliminary studies indicate the bridge would be 4.25 miles (6.85 km) long, with one 1500-foot (460 m) cable-stayed span over the main channel of the river supported by two 450-foot (137 m) towers. A cost of $565 million has been estimated. The structure's name is derived from Charles W. Dean (1927–1998), an engineer from Cleveland, Mississippi who proposed the bridge in 1984. A Mississippi legislative act named the proposed bridge after Dean in 1999. ==History and development== The Great River Bridge was originally proposed by Mississippi engineer Charles W. Dean in 1984. Originally part of the planned relocation of US-278 through the lower Mississippi Delta, the Federal Highway Administration (FHWA) approved the environmental impact statement (EIS) and issued a Record of Decision (ROD) for the bridge in 2004. It has been determined that the Charles W. Dean Bridge will also carry Interstate 69, following FHWA approvals for sections of I-69 in Arkansas in 2006 and Mississippi in 2010 that will connect to either end of the bridge. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Charles W.
