Stone Arch Viaducts in the Southwest?

[Sampug394]

Hello All, I've Ran into a little Stump I'm Trying to get around.

On my Route 'Beckly Cliff & Tumbleweed', I've gotten the Track into a Series of Canyons, And I'm Stuck at one Point, Wondering:

Where there ever any Stone Arch Bridges in the Southwest? I'm not sure whether I should implement one, or Use a THIRD Stoney Creek Steel Arch to bridge the Gap...

Not that I'm aware of - generally wood bridges / trestles early on; iron / steel later. I want to give 1900 is an approximate cutover date, but have very minimal documentation to back that up. If the distance is too great for a wooden bridge, the rail line would go down the side of the canyon (probably using switchbacks) and go across the bottom, using a small bridge over the river / stream.

Thank You. This is What I figured, but For the Gap, I managed to put in place a Really Big 'Lekbrug' Arch Bridge...
