MIDDLEBOURNE, Ohio (AP) - The last S-curve bridge in service in Ohio is being closed to traffic because of concerns that heavy trucks used in the modern drilling boom are too much for a structure once traversed by wagons, Model T's and even Abraham Lincoln.
Guernsey County commissioners on Friday closed the bridge over Salt Fork Creek near Middlebourne, about 95 miles east of Columbus. It's an effort to preserve the span, which is part of the trail known as the National Road that connected Maryland and Mississippi River.
The president of the Ohio National Road Association, Doug Smith, says the bridge probably was built around 1828. It's a National Historic Landmark and a National Engineering Landmark.
Advocates hope to turn the area into a park.
