What Made Campbell's Bridge Special?
Campbell's Bridge was designed by A. Oscar Martin. The Dailey Construction Company built it.
This bridge was very important because it was one of the oldest examples of a special type of bridge in the United States. It was a reinforced concrete arch bridge. This means it was made of concrete with strong metal bars inside to make it extra sturdy.
A Historic Landmark
Because of its unique design and age, Campbell's Bridge was added to the National Register of Historic Places. This happened on June 22, 1988.
Being on this list means it was recognized as an important historical structure. It was a part of engineering history.
Why Was the Bridge Replaced?
In October 2005, the road where the bridge was located had to be closed. This was so the old Campbell's Bridge could be replaced.
The original bridge was a single-span bridge. This means it had one main arch or section crossing the creek.
The New Bridge
The plan was to finish the replacement work by December 2005. The new bridge is much bigger than the old one.
It is 120 feet (37 meters) long and 32 feet (10 meters) wide. The new bridge is built in a modern style called a concrete box-beam. This design is very strong and common today.
