Baltimore & Ohio Railroad Bridge No. 451/1 crosses the Cuyahoga River carrying switch tracks to Jaite Company.

The plant, founded in 1905, produced up to eight tons of paper per day. This level of outgoing freight, incoming raw materials, and the fact that Jaite Co. paid for the bridge construction, made such an expensive switch lead attractive to the railroad. Right of way for the switch lead was secured in 1907, and construction was completed by 1909.

Bridge No. 451/1 is a through Pratt truss. It is 138 feet 9 inches pin to pin, and has a clear width of 13 feet 9 inches and a 19 foot 10 inch height clearance. Carnegie steel supplied the steel.

The bridge was surveyed for the Historic American Engineering Record, a project of the National Park Service. More info is available in the Library of Congress. The plans were delineated by Dana L. Lockett, Julie E. Pearson and Donald M. Durst in 1987.

  1. How do I get these plans? I am not that good with the computer. I would be more than happy to pay for these if they were mailed to me. Lance S. Bender

    1. Hi, thanks for visiting the website! If you left-click with your mouse on the plan image it should open the full size file. Right click on the new large image that opened and a dialogue box should pop up. Choose the “save image as” option and type in the location on your computer you want to save the file to. This will download the file to your computer, where you can print it. Or if you want, put it on a small USB drive and take it to a copy shop for printing.

      You can also send me a message on the Contact Us page with your email, and I can email you a PDF of the files to take to a copy shop. There may be a delay, as I’m currently in the field, and my computer database on which the files are stored is 1,600 miles away.
