<p>What is a Bridge? A bridge is a structure carrying a path of some sort, whether it be a hiking path, road, railroad, or even a canal over some sort of obstacle such as a river, ravine, another road or railroad, or other type of obstacle.</p>
<p>The oldest known datable bridge in the world that, believe it or not, is still in use is the slab-stone single-arch bridge in Izmir, Turkey which goes over the river Meles. Izmir is formerly known as Smyrna. This bridge dates back to c. 850 b.c. There are remnants of Mycenaean bridges that still exist in the neighborhood of Mycenae, Greece that cross over the River Havos. These bridges are believed to date back to c. 1600 bc.</p>
<p>The oldest surviving roadway bridge in the United States is the Frankford Avenue Bridge which was erected in 1867 in the Holesburg section of Northeast Philadelphia, Pennsylvania. This 73-foot-long three-span twin stone arch bridge carries Frankford Avenue, also U.S. Route 13, just north of Solly Avenue, over Pennypack Creek in Pennypack Park. This bridge is also commonly known as the Pennypack Creek Bridge, the Pennypack Bridge, the Holmesburg Bridge, and also as the King's Highway Bridge.</p>
<p>The oldest bridge in Kansas, that I know of, is the Wea Creek Bowstring Arch Truss Bridge in Topeka, Kansas.
