Title: Non-standard overpasses
Post by: ethanhopkin14 on February 17, 2021, 02:37:42 PM
I am thinking of a few instances where a road goes under an interstate through a glorified (https://goo.gl/maps/srR8qDsRkeJkJPQ28) box culvert. (https://goo.gl/maps/286N6fNqs64nPwpu7)

Any other examples of odd overpasses?

US 66 under I-44 (https://www.google.com/maps/@35.6810122,-97.0466736,3a,40.1y,267.12h,86.57t/data=!3m6!1e1!3m4!1sAMbJHq-NDESUR1dZN4N6Eg!2e0!7i16384!8i8192) isn't quite a box culvert, but I think "non-standard" fits.

That underpass looks like I would get tetanus just driving underneath it.

So many of the OTA overpasses done in the 1950s are just...bad.

This one (https://www.google.com/maps/@35.2764696,-97.6046727,3a,75y,287.94h,66.05t/data=!3m7!1e1!3m5!1sss1GEe3EhbWcmGmZMDzl4A!2e0!6s%2F%2Fgeo0.ggpht.com%2Fcbk%3Fpanoid%3Dss1GEe3EhbWcmGmZMDzl4A%26output%3Dthumbnail%26cb_client%3Dmaps_sv.tactile.gps%26thumb%3D2%26w%3D203%26h%3D100%26yaw%3D299.34378%26pitch%3D0%26thumbfov%3D100!7i13312!8i6656) hasn't been fixed yet despite being in a town of 7,600 and on the same road as a major destination for out-of-towners (not that this is part of the route there, but it's one wrong turn away).

Naw, it's okay.  I was thinking interstate, because of the odd things you can find on non interstates making the odd ones you find on interstates a bit rarer, but I don't think this has to be exclusively interstate.

Makes me wonder what the purpose of those ramps and the culvert is. Convenient turnaround?

Not a road, but something I thought of.

The SkyTrain (Vancouver rail system) has an underpass at Templeton St (https://goo.gl/maps/yryCt2n3a3fw94LE6) that was built more like a tunnel than an underpass. I suspect this is done for safety reasons, such as keeping people off the third rail.

This underpass in Puyallup, WA (https://www.google.com/maps/@47.1894141,-122.3277429,87a,35y,327.47h,54.37t/data=!3m1!1e3) is very similar to the OP. I think it was built to connect the two WSU campuses without requiring people to cross over the busy street dividing the campus. Road was first, so I guess it was easier to build than constructing a bridge.

Yes.  The graffiti one also doubles as an actual culvert.  It obvious in the desert, 99% of the time it's not used as a culvert, but that 1%....

There was one on I-25 between Colorado Springs and Denver, but it is being turned into a bridge during the construction of the express lanes. Here (https://goo.gl/maps/3zkVEZ5bkQTc1GsD9) is what it looked like.

when we visit our grandparents in New Mexico, we sometimes take old US 66 just for fun, and the old road goes under the highway in this (https://goo.gl/maps/T64uQ2huL5wqVgsw6).

And, although not on the interstate, this (https://goo.gl/maps/cZFzbrtE7H9VyE4A7) is in the same area, and it is literally a big culvert. The google car hasn't been there in a looong time, but from what I remember, it was similar to this (https://bnxo223rnq71rkvla2y3v3d7-wpengine.netdna-ssl.com/wp-content/uploads/2020/10/1436990854_IMG_2261-1024x767-2.jpg). I'm sure there are other haul roads that do this, but it's the only one I have seen.

That is a pretty ubiquitous design for a rural rail underpass.

Primary purpose is probably to allow for ranch access. Look at the south side of the interchange (https://goo.gl/maps/hTqdUJd3prWefp7h9).

Not sure you can classify them as an overpass, but would the Illinois Tollway oasis count? Certainly not a standard overpass.

Well, and 7 to 8 feet is pretty standard parking garage clearances. Maybe not quite enough to fit that lifted truck, but high enough for most (if not all) regular cars.

While most parking garages are that low, bridges usually aren't, not unless they are going over a waterway or pedestrian path. And even then, usually they are at least around 10'.

Of course, yes. And in the US, it would certainly be signed out the ying-yang as drivers would have repeatedly hit it. A bit like this 8-foot clearance underpass (https://goo.gl/maps/2ZGL68HUMTXh1XUR7) in Renton, WA.

Here is a better view: https://goo.gl/maps/ohsgTrv6PaFSf1w5A

Based on that mid-2000s Mitsubishi Endeavor in the foreground, I would guess the clearance is around 8 to 9 feet.

There is an 8'0" railroad underpass (https://goo.gl/maps/zigGNg7ZFffDMaN5A) in Springville, Utah. Naturally, GSV couldn't go under it either.

I have no idea why it's there...it's not that old of a structure, the railroad line has multiple grade crossings already, and 1600 South is not exactly a high-traffic road (and it already has a grade crossing at another line just to the west). Seems like this could have just been a grade crossing.

Culverts as underpasses are pretty common in the west and midwest, as I've found researching my posts for the ORIGINAL Interstate Bridge Designs From Every State (https://www.aaroads.com/forum/index.php?topic=26007.0) thread. Of all the ones I've found, this one in Illinois (https://goo.gl/maps/QWr55hAg8PRPxi856) is my favorite.

Well, and 7 to 8 feet is pretty standard parking garage clearances. Maybe not quite enough to fit that lifted truck, but high enough for most (if not all) regular cars.

While most parking garages are that low, bridges usually aren’t, not unless they are going over a waterway or pedestrian path. And even then, usually they are at least around 10’.

Of course, yes. And in the US, it would certainly be signed out the ying-yang as drivers would have repeatedly hit it. A bit like this 8-foot clearance underpass (https://goo.gl/maps/2ZGL68HUMTXh1XUR7) in Renton, WA.


The previous Renton bridge on the site: 6-6.

Also, the Snoqualmie Pass Wildlife Crossing (https://goo.gl/maps/eFFE3pSzjeKvx4vr5) was built as a culvert, then filled in.

If that is 8' 0" , than the bridge linked before might be even lower! Maybe only 5-6'!

Here is a better view: https://goo.gl/maps/ohsgTrv6PaFSf1w5A

Based on that mid-2000s Mitsubishi Endeavor in the foreground, I would guess the clearance is around 8 to 9 feet.

I've seen similar things done for pedestrian underpasses, but this is the only vehicle underpass I've seen built like this.

Another (somewhat less) unusual design is the concrete arch underpass (https://www.google.com/maps/@48.1063282,-123.3470683,3a,60y,12.17h,98.22t/data=!3m6!1e1!3m4!1sxSImfSoNaLi7UgAeX8RYaQ!2e0!7i16384!8i8192?hl=en) on Dear Park Road just east of Port Angeles.

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.

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.

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: (https://scontent-ort2-2.xx.fbcdn.net/v/t31.18172-8/13087204_10209828662018141_2142806144022167009_o.jpg?_nc_cat=111&ccb=1-7&_nc_sid=b9115d&_nc_ohc=Lf2U2aFAcEIAX_xaMI_&_nc_ht=scontent-ort2-2.xx&oh=00_AT9Pkl4MN9X95tZnPr5XsLadk8KUtAASGXdCiXV-oSbowQ&oe=630CBDB0)

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.

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 (https://goo.gl/maps/srR8qDsRkeJkJPQ28) box culvert. (https://goo.gl/maps/286N6fNqs64nPwpu7)

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.

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.
