This is a neat piece of history that you can still walk across today. There is both an official Ohio historical marker and a kiosk with photos that offer more information about the bridge. As the name indicates, it has an "S" shape, and it is part of the historic National Road, which runs across six states. Built in 1828, it is thought to be the first bridge built in the Northwest Territory. The bridge is built at a 6.3% incline to cover a 500 foot climb over Wheeling Creek. The bridge had to be partially rebuilt in 1929, and was then repaired again beginning in 1999. The Blaine Viaduct was built in 1933 and took over some of the heavy lifting with traffic. The Blaine S Bridge became the state's Bicentennial Bridge in 2001. If you walk across the bridge, you can also glimpse some remnants of the old road on the other side (but watch your step, it's a bit uneven since it hasn't been maintained and grass has partially taken over). Some picnic tables and benches have been put in on this side. The S bridge was built using three arches, which you can view by heading down to the bank of the creek. Very interesting bit of history! read more
