High Bridge is a nearly 300 foot high railroad bridge over the Kentucky River which gives the community its name. The Kentucky River runs through Kentucky River Palisades for much of the lower portion of its length. Most of the bridges over it in the area are relatively high ones.
High Bridge was opened in 1876 and was the first cantilever bridge in North America. It Standing 275 feet over the river between the Palisades, it first carried both passenger and freight trains. The American Society of Civil Engineers has designated it a National Engineering Landmark. Freight trains of the Norfolk Southern Railway still use this bridge several times a day.
The John A. Roebling Suspension Bridge spans the Ohio River between Cincinnati, Ohio and Covington, Kentucky. When the first pedestrians crossed on December 1, 1866, it was the longest suspension bridge in the world at 1,057 feet (322 m) main span. Today, many pedestrians use the bridge to get between the arenas in Cincinnati (Paul Brown Stadium, Great American Ball Park, and U.S. Bank Arena) and the hotels, bars, restaurants, and parking lots in Northern Kentucky.
The bridge was listed on the National Register of Historic Places in 1975 and designated a National Historic Civil Engineering Landmark in 1983. It remains the busiest of Cincinnati's four non-expressway automobile or pedestrian bridges. Initially called the "Covington-Cincinnati Suspension Bridge," it was renamed in honor of its designer and builder on June 27, 1983.
