The National Road in Ohio: Two reroutings for flood-control projects, and the abandoned town of Tadmor, in Montgomery County

Over Memorial Day weekend in 2011, my dog Gracie and I explored the National Road all the way across Ohio. That road is now US 40 in most places. I’m bringing the long trip report over from my old Roads site.

In March of 1913 more than eight inches of rain fell on frozen ground in the Great Miami River watershed. The water couldn’t sink into the ground so it ran off, broke through levees, and flooded the city of Dayton up to 20 feet deep. It remains Ohio’s greatest natural disaster. So that this could never happen again, the Miami Conservancy District was formed, which built levees and dams and even straightened the river channel. Unfortunately, this work caused the National Road to be rerouted in two places directly north of Dayton. The re-routings aren’t particularly graceful, either. But the flood-control project worked. In the years since, parks were built in some of the displaced land.

As I made my way from east to west, I first encountered the rerouting around the Taylorsville MetroPark.

Taylorsville Dam

It is well commemorated.

A great dam carries US 40.

Before any trip along the National Road, I normally consult George Stewart’s great book, US 40: Cross-Section of the United States of America. Stewart drove US 40 across the country in 1949 and 1950 and took photos along the way. I like to photograph the same places he did. I simply forgot to check Stewart’s book before this trip, but after I returned home I was delighted to find that I had taken a photo of this dam from the same place he did.

Tadmor was a little town on the National Road’s original alignment north of this dam. It suffered some damage in the 1913 floods, but a covered bridge over the Great Miami River remained intact, and traffic still moved through Tadmor, and so townspeople stuck around. But when the National Road was rerouted over this dam, Tadmor’s future dimmed considerably and so everybody left. I’ve marked the approximate location of Tadmor on this map segment. As you can see, some of the original National Road survives as park roads.

Very little is left of Tadmor today, but the site is reachable via the trails inside Taylorsville MetroPark.

Tadmor, OH

A small sign says you’ve arrived.

I understand that the foundation of at least one house, the abutments from the covered bridge, and perhaps evidence of the old road remain, though they require some effort to reach. Unfortunately, it was 98 degrees this day, and by the time my dog and I got here the heat was beginning to affect us. We needed to get back to the car where cold water awaited us. Before we turned around, we did see these abutments from what I’m guessing was a railroad bridge.

Tadmor, OH

I tip my hat to my road-loving colleague Denny Gibson who visited Tadmor before me and wrote about it. I probably wouldn’t have known about Tadmor otherwise!

Next: Ending the trip with one last (short) old alignment.

    I have always wanted to stop and explore this area but it seems I’m always in a hurry or the weather is poor. This is inspiring!

      Tadmor is fun to go see. Don’t do it on a 98 degree day as Gracie and I did, though.

        Duly noted.

    I have enjoyed Stewart’s book and have it in my collection. One of my all time favorites is US 40 today by Thomas and Geraldine Vale.
    They retraced Stewart’s route 30 years later and attempted to photograph the exact same locations. The changes in many cases were dramatic.
    I always dreamed of doing the same thing.
    Sounds like Jim could do this on at least part of the route. How about it Jim?
