The name used appears to say the bridge is made of steel.
The actual name is Steele's Bridge and Steele's Bridge Road. It was named for the family who actually put up the bridge pre-civil war. Their homestead was next to the original covered bridge and they were allowed to charge a toll.
The original Covered Bridge was burned down in 1976. A new bridge built by the Chumleys (who were kin to the Steeles) was built using steel trusses.
The name remained Steele's Bridge and the road Steele's Bridge Road.
