Williamstown-Marietta Bridges over Ohio River

This bridge is another example of cantilever bridges that are replaced in the 1990s are replaced with truss bridges whereas those replaced in the 2000s use cable-stayed bridges.

"The Williamstown-Marietta Bridge was the first highway bridge in the United States built in a cantilever fashion over an inland river." Because it was in such bad shape, it was closed to all traffic on July 17, 1985. [HAER-data] Note that the replacement wasn't available until 1992.

This illustrates why it is so important that cantilever bridges allow the bridge to be built over the navigation channel without any falsework. Note too many boats could pass through that falsework.

Back then, they did not use big cranes on barges like they do today, they used custom-built, travelling gantries.

She was hugging the bank I could have jumped on deck. Down bound under Williamstown bridge.
William Reynolds: She was trying to avoid the Marietta College Crew who were crossing the river to start up the Muskingum. Good move Capt.

A.G. Bertin posted two photos with the comment: "From September 2020, here are a couple photos I took of the other bridge that crosses the Ohio River between Williamstown WV and Marietta OH. (Yesterday I posted a photo of the I-77 bridge.)"

Nice big tow out ahead of the CAPT. RICK NEALE today as she heads upriver past Marietta, OH. This tow of barges will be loaded with more than 6 million gallons of oil products, which will be refined and in your gas tanks very soon!
William Stewart: Good to see the old Humprey out running again. Some old shipyard guys at Neville Island told me best boat they ever built.
