This 862' (263m) long bridge has a main span of 420' (128m). [ArchviedBridgeHunter_Andrew]

It had a much-needed rehabilitation in 2015.

The repairs were done while traffic continued to use the bridge. They replaced one brace at a time by installing a temporary brace, demoing the old brace, installing the new brace and then moving the temporary brace to the next position to be replaced.

I found this bridge while looking for the arch bridge. It is interesting that they used two short leaves rather than one more normal length leaf.

The length of the bridge is 90' (27m). [ArchivedBridgeHunter_Blynman]
