What is it about Bridges and Tunnels?


It is actually estimated that in the Unites States there's a bridge for every mile of railroad built. Basically a comparison of bridges vs. miles of railroad. Even traveling through seemingly flat midwestern prarries one can see hundreds of dry creeks, which only become streams during rainfall with wooden beams bridges crossing them.

Certaintly true, can’t have the rails dipping into a dried up creek or filling in a dried up creek to make it flat cross over.
 
I personally use tunnels to hide the track passing through impossible curves, or an excuse for a road access

I personally love the large wood USA bridges but as I model England have no excuse to fit one in
here in the UK we are more modest, not ny choice, if I could I would go big
this is Goathland, immortalised in Harry Potter, but they stick to the platform, when you compare our style of bridge to the USA you get why lol

Probably because tunnels make good view blocks, and trains going over bridges are just cool!
That is what I think too. Tunnels are used on model railroads to help hide some of the roundy round appearance and break view from one scene to the next.

Bridges are a different matter. No railroad, even out here on the flat plains of Kansas can get very far without having to bridge or at least culvert over a river, stream, road, cow path, dry gully. or whatever.
 
I have no tunnels, but I have three bridges because they look cool.
My layout won't have any tunnels, because North Central Wisconsin. At one time, there was a series of 3 tunnels closer to Tom O- starting west of Fort McCoy, it ran from Sparta southeast to Elroy and was reportedly the first "rails to trails" park in the country. However, I do plan to have a bridge or 2 to span the surrounding rivers and creek beds.
 
And then there are the Chinese, who seem to have a fondness for stringing strands of spaghetti...er...noodles, sorry...through mid-air.

[Warning! No airborne railroad tracks involved at all (as best I can tell), but there could be a ground-hugging rail line near the left edge. So avert your eyes if you are at all squeamish]



Of course you can always overdo things too:


I'll need triple martooni...er...martini after this. No, I mean I'll need a second triple mar.........tini after this.

Fun thread. :D
Snowman- as anyone who has been to Trainfest in West Allis, WI can attest, that last picture bears a striking resemblance to the infamous "Zoo Interchange" at the junction of Interstates 41, 94 and 894. 😄😂
