Title: Bridges over Bridges
Post by: ethanhopkin14 on July 21, 2021, 02:31:27 PM
I am looing for examples of bridges crossing over another bridge.  This excludes bridges at freeway interchanges.  This (https://goo.gl/maps/KS3TDkwbUWCwj1RS6) might be my favorite example.  Bonus if you look at this view (https://goo.gl/maps/2j48ox9AZnW9w7eW7) of the same bridge, you can see the low water crossing that was the first bridge.  They all don't get crossed, but it's cool to see three generations of bridges!

There is a famous example in Richmond.

My impression is that you are talking about the famous Triple Crossing (Seaboard bridge over C&O Viaduct over Southern at-grade).  However, this is right beside a bunch that are lesser known but more impressive in their own right: 
If you include the footbridge over the James and Kanawha Canal, there are six different levels of bridges intertwined at this location.  Not all of them stack.

My impression is that you are talking about the famous Triple Crossing (Seaboard bridge over C&O Viaduct over Southern at-grade).  However, this is right beside a bunch that are lesser known but more impressive in their own right: 

       
  • Just to the east of Triple Crossing, the I-95 interchange with the Downtown Expressway (Toll VA-195) has also got the I-95 mainline bridge and two ramp bridges over the C&O Viaduct.
  • Then just to the north of the Triple Crossing, three of the ramps from I-95 to/from the Downtown Expressway cross over the Seaboard Viaduct (mainline).  All of these are crossing over Dock Street (at grade).
  • Next up is the I-95 mainline bridge also crosses over the Seaboard Viaduct (mainline) coming off the south end of Main Street Station, which crosses over US-60 (Main Street, at grade) at the same location.
  • Almost, but not quite:  The Seaboard Interchange Viaduct (to the C&O) is just touching underneath the Downtown Expressway ramp to I-95 northbound.
If you include the footbridge over the James and Kanawha Canal, there are six different levels of bridges intertwined at this location.  Not all of them stack.
Oh, I didn't realize that there's more than just that.

Both of those could be true at the same time.  Or neither one could be true.  And, come on, we have no idea how it looks to you unless you tell us.

Gotcha.  OK.  As a matter of fact, I did open the link and look at the overpass.  And, because you've informed me that just looking at it will let me know if you think it's too low or not, I can safely answer the question correctly.

The answer is "The overpass does not look too low to you."  Therefore, logically, by the implication contained in your question, the second answer to your question is "It's just you."  After all, you implied that it can only be one or the other.

If you disagree, then either (a) you were wrong in asserting that merely looking at it would tell me what you think about it, or else (b) you're wrong, or else (c) you phrased your initial question incorrectly.

It might be worth mentioning that there is a near miss just north of there, with the same road and railroad track, near 50th st. The 50th st bridge is just feet away from going over the RR bridge over 235.

Interesting!  That one got me thinking about the catwalk under the New River Gorge Bridge, and if that would count as a "Bridge over a Bridge".  (Or maybe it is just kind of a "double decker bridge").  (It is interesting nevertheless).

Interesting!  That one got me thinking about the catwalk under the New River Gorge Bridge, and if that would count as a "Bridge over a Bridge".  (Or maybe it is just kind of a "double decker bridge").  (It is interesting nevertheless).

Looks like a new thread:  Bridges under Bridges.

This reminds me of the time I took some friends on a camping trip so that they could see the New River Gorge Bridge up close and personal.  The original observation deck was still in use, and we were surprised to see a fellow free-scaling across the eastern arch structure.  We probably stayed for an hour watching.  It was fun trying to negotiate all of the hairpins on (then) WV-82 under the bridge in my 1985 Pontiac Catalina, which required three-point turns in several of the curves.

The US 1/301 Lee Bridge in Richmond also has a pedestrian bridge hanging underneath it from its north end to Belle Isle.

I-294 over both US 20 [Lake St.] and IL 64 [North Ave.] in Northlake IL. The Lake st./20 bridge was first built in the 1930's and was a truss design, replaced a few years ago with plain bridge. Was amazed at it as a kid and now I go over it to work daily.

Here's an example (https://www.google.com/maps/@41.2934198,-91.7249572,3a,70.8y,88.23h,85.69t/data=!3m6!1e1!3m4!1svOM6TP2dHgjAg3WNoiXtEQ!2e0!7i16384!8i8192) on county road G38 just west of Washington, Iowa where the road simultaneously crosses over a creek and under a rail bridge. This setup used to be even more interesting, because if you look at the 2009 Streetview you can see that the road bridge used to be a pony truss. That pony truss dated back to the original paving of the road in 1928, when it was part of what is now IA 92.

Here's a much newer example (https://www.google.com/maps/@42.4747168,-90.7615463,3a,83.8y,15.94h,80.55t/data=!3m6!1e1!3m4!1scVMcUCNlxJk8JAKDiEHqEA!2e0!7i16384!8i8192) on US 20 just west of Dubuque at a new interchange with the relocated US 52. I really like the guardrail design they used here on US 20. I wish they'd do stuff like that more often.

There's that point where the Garden State Pkwy goes over the NJ Turnpike (https://goo.gl/maps/Zd7Yf8JTixHZBj1J6) in Woodbridge Twp.  NJ 514, a.k.a. Main St., diagonally crosses them both.  While this is all near Interchange 11 on the pike (and GSP Exit 129), it is technically not part of the ramp structure.

It's not a bridge over a bridge, but I've always been amazed by the railroad bridge just east of there, which appears to be held up with timbers.

It no longer exists, but in Clinton, Iowa, there was a bridge over the Mississippi River to Illinois that went over the Chicago Northwestern RR bridge.  That bridge was replaced by the Gateway Bridge, which carries US 30 today.
