Within Indianapolis, the National Road used the original alignment of U.S. 40 along West Washington and East Washington Streets (modern U.S. 40 is now routed along I-465). East of Indianapolis, the road went through the city of Richmond before entering Ohio, where the road continued along modern U.S. 40 and passed through the northern suburbs of Dayton, Springfield, and Columbus. West of Zanesville, Ohio, despite U.S. 40's predominantly following the original route, many segments of the original road can still be found.
