 were invited to submit designs and estimates for a bridge over the east channel of the river to Wheeling Island. In doing so, the design was set as a suspension bridge, as Ellet and Roebling were the foremost authorities on the topic. Ellet received the contract award in 1847 and began the same year. The bridge was completed in 1849.

On May 17, 1854 a strong windstorm destroyed the deck of the bridge through torsional movement and vertical undulations that rose almost as high as the towers. Ellet rebuilt it, followed by improvements in 1859 by Ellett's partner William McComas

 and Hildebrand. The deck was completely rebuilt in 1956, when the road was widened from 16.25 feet (5 m) to 20 feet (6.1 m) and the sidewalks were correspondingly narrowed. The road and sidewalk were reconstructed with an open steel grating that reduces wind resistance, and rests on lightened steel floor beams. In the early 1980s, the West Virginia Department of Highways restored the bridge.. The bridge remains in active service.

The bridge spans a distance of 1,010 feet (308 m) across the Ohio River and allows barges to pass underneath. It remains the oldest vehicular suspension bridge in the United States still in use and is listed as both a National Historic Landmark

On February 17, 2011, a vehicle driving at a high rate of speed lost control and crashed into the sidewalk panels on the bridge. The damage to the bridge was enough that it was closed for inspection. The bridge is estimated to be closed for four to five days so the panels can be fixed and other minor repairs.

Weight limits

The bridge was designed prior to the advent of the automobile. At the time of construction, a horse and buggy was the heaviest live load that would be expected. Currently, the bridge has a (per vehicle) weight limit of 4000 lb (1,814.4 kg) making it unsuitable for trucks, buses, or other heavy vehicles.

Traffic is advised to keep at least 50 feet (15.2 m) between vehicles. Additionally, traffic lights at both ends only allow a certain number of cars onto the bridge at one time.
