Bridges have been at this local spot about 180 years. A new $21M one is coming.

A bridge has spanned the Great Miami River at Third Street in Dayton for about 180 years, according to local accounts. And come 2020, Montgomery County is set to begin constructing the newest version, coming in at a cost of $21.6 million.

Here are Third Street bridges past, current and future:

The original wood-covered bridge was built about 1840 and had limestone piers.

In about 1904, a concrete-arched bridge was built. Since concrete came into use, stone from the old piers was taken out and left unwanted for years at the corner of Salem and Oxford avenues, according to an 1881 account by one Charles F. Sullivan as published by Dayton History Books Online.

The most recent upgrade was completed in 1949, giving the bridge its current look.

By the end of 2022, there should be a new bridge in place that not only transports traffic, but is also a destination to learn about the historical achievements of Daytonians.
