With these improvements, residents and businesses have been attracted to formerly blighted areas. Municipal projects have included construction of a softball complex, which hosted the 1996 Olympic softball competition; construction of the Chattahoochee RiverWalk; construction of the National Civil War Naval Museum at Port Columbus, construction of the Coca-Cola Space Science Center, the expansion of the Columbus Museum, and road improvements to include a new downtown bridge crossing the Chattahoochee River to Phenix City. During the late 1990s, commercial activity expanded north of downtown along the I-185 corridor.
