The Lost Bridge Trail is a 5.0-mile rail trail in Sangamon County, Illinois. It was built by the Illinois Department of Transportation along an abandoned Baltimore and Ohio Railroad corridor between the east side of Springfield, Illinois to the center of Rochester, Illinois. The trail crosses the South Fork of the Sangamon River near Rochester, and crosses Sugar Creek near Springfield. Sugar Creek carries the outflow from Lake Springfield, a sizable nearby reservoir.
