Two bridges at Blaine
Canon PowerShot S95
One bridge was built in 1826, the other in 1932. One guess which is which!
Both bridges carry the National Road/US 40 over Wheeling Creek near Blaine in Belmont County, Ohio. It’s just five miles from the Ohio River, the border with West Virginia.
The lower bridge came first. It’s the oldest standing bridge in Ohio, and is the longest of the few remaining S bridges in the state. Notice its “S” curvature? This was done in the name of economy: it’s less expensive to build and maintain a bridge that’s perpendicular to the creek it crosses. They merely curved the approaches to meet the road.
This was just fine in the days of horses and buggies with their slow speeds. As automobiles took over, it became a hazard. Drivers had to slow way down to negotiate the S. Some didn’t slow down in time.
Moreover, west of this bridge lay a very steep hill. It was challenging for cars of the day to climb. I’m sure pedestrians and horses didn’t much enjoy the climb either!
The upper bridge made travel easier on three counts: it eliminated the S, it offered a wider deck (38.1 feet vs. 26.9 feet), and it created a gentler rise to the top of the hill.
I know of four other S bridges on the National Road: one in Pennsylvania (here) and three in Ohio (two here, the third here). That last one was still open to traffic when I visited it in 2011, and I drove over it. By 2013 it, too, was closed (here).
