The Famous Drawing is probably wrong?

edit

The drawing that is (correctly) cited from a dictionary shows a 'flat topped' trestle. However, the National Registry of Historic Places information on the viaduct as an architectural site shows a photograph of an excavated 'square/trapezoidal' truss. I'm not a civil engineer, so forgive my poor names for these structures and possible misunderstanding, but those images seem irreconcilable. I'm inclined to trust the photo on this, but I'm neither a historian, archeologist, or even habitual Wikipedia editor, so I don't feel comfortable putting anything in the article text. 2601:19E:427F:C7F0:8D3C:E3F3:8022:B4B9 (talk) 07:17, 21 August 2024 (UTC)Reply

What you're seeing in the photos is the deck of the bridge, where the tracks would be attached. The viaduct is a deck truss, which means the trusses are located underneath the deck. So the tracks were at the very top of the bridge, meaning the drawing isn't necessarily wrong. I happen to be a civil engineer. Hopefully this makes sense.

Thanks! I totally did not understand that without your explanation. Sorry for the erroneous complaint. 137.99.108.59 (talk) 17:03, 28 August 2024 (UTC)Reply
