Back to the culverts.  I noticed that in Victoria, BC there was a railroad that passed under a round culvert.  Now it's a trail.  Sometimes in the 70s, Seattle Times cartoonist Alan Pratt drew a proposed solution to traffic problems.  The first panel was an exaggerated spaghetti interchange, and panel two was the same interchange, but built with culverts.  The logic was that since culverts are so common, they must be cheaper, and if only the state could build highways with all culverts, they would be affordable.  With the Seattle Times archive available online, I've been trying to find this cartoon, with no luck.

That intersection hurt my head.  So it imitates left side of the road driving?  I think.

Not really. Except for the frontage roads, it has a similar layout schematically as I-59-20-65 in Birmingham or the original I-95 north-I-695 in Baltimore. Its compressed size and low design speed allows it to be done with four bridges instead of eight, with the rest in tunnels or culverts.

^^ Interesting way to lengthen a bridge without replacing it.

This one is not only "irregular," but also reportedly one of the oldest underpasses in NJ.

This at the US 11/ I-10 interchange east of NOLA.


Don't tell ODOT that those aren't normal.  That is like 80% of the bridges over I-5 along the Willamette River in Portland.  Of course, most of those overpass structures are built like they were rendered on an Commodore 64, all straight lines.

They said take a left at the fork in the road.  I didn't think they literally meant a fork, until plain as day, there was a fork sticking out of the road at a junction.

This is a legit bridge but the wing walls flanking it, and the fact that it just looks like a place for water to cross the interstate give it a very culverty feel.

Of relatively recent vintage, there's a double-barreled culvert carrying a street under I-77 in Columbia. Two, actually: this one under an offramp, then this one.

There's this one in the Binghamton area, from Watson Blvd. to NY 17C West just outside of Johnson City: https://www.google.com/maps/@42.1175574,-75.995316,3a,75y,139.37h,65.28t/data=!3m6!1e1!3m4!1s6Vethd5lpfTfyIWdcyR3rA!2e0!7i13312!8i6656

This used to be a shortcut for farmers and livestock to access farm lands on the river (hence its size), and dates to 1849. Here it is being used by a trolley car around 1900:

It's also a bit weird in that it's currently a one-way on-ramp onto 17C, where 17C's one-way roadways are split across NY 17: https://www.google.com/maps/@42.1171004,-75.9949138,3a,75y,293.5h,78.83t/data=!3m6!1e1!3m4!1ssxYtU7vJYzBH07z9QoGdOA!2e0!7i16384!8i8192

Kyle St. in Manville has a very low 7 foot 8 overpass. GSV dates all the way back to Sep 2007 and in 2022 it has not been raised since.

I always found the Eads Bridge underpasses in St Louis different as the bridge has two levels, the lower being for light rail. There's also this box culvert in nearby Valley Park.

West Grand Boulevard in Detroit, passing under the Michigan Central tracks south of Michigan Avenue.  In the ancient time when I was a wee lad, before freeways, this was on the way to the Ambassador Bridge from the west side (Michigan to Grand Blvd. to Porter).  My dad would always honk the horn as we went under to hear it echo.  Clearance is only 8' 10".

I am thinking of a few instances where a road goes under an interstate through a glorified box culvert.

Any other examples of odd overpasses?

Here's one under Kansas Highway 10: https://goo.gl/maps/F4LGPqf7pQ8Y9AHa7 .  I wonder what's going to happen to it when they widen K-10.

Aguascalientes, Mexico, says "Hold my beer."

That's slick!  Does this type of interchange have a name?

It appears to be a combination of a braided and stack interchange, and the frontage roads create a 3-level diamond interchange as well.

IMO, looks more like a compact version of the I-65/I-20 I-59 interchange in AL, just with service roads.
