What do you call one of those odd shaped, corrigated pipes; it's 5' high and at about 1/4 of the way up from the flow line it's 7' wide.
TIA for the knowledge of this board...:-D

Elliptical Pipe.
It's a thingamabob. AKA as corrugated metal pipe-arch (CSPA, CASPA, CAPA).
Corrugated Metal Arch Pipe CMAP?
Have a great week.
edit: that ole fart I,m looking at directly above me beat me to it! 😉 Drat.
Back in the old days we always called them "squash pipe".
Yes, it's elliptical. (oh yea, arch pipe.... whatever)
One thing to be aware of is that they only come in pre-fab sizes. So if you say that one is 60 x 84, it may really be 62 x 82 (per pre-fab specs) and the engineer will call you out because he KNOWS they don't make 60 x 84. But is it from the top of the corregation, or the bottom?
Soon learned to put +/- after the dimensions.
WOW! You guys are good! and quick too...:-)
I here what you are saying wayne, some contractors and/or engineers are soooooo picky:-P

Oh these ones,
we even know them over here in Belgium

The particular pipe arch you are looking at would likely be one of the following:
6'-9" x 4'-11" structural steel pipe arch.
7'-0" x 5'-1" structural steel pipe arch.
7'-3" x 5'-3" structural steel pipe arch.
Stamdard 6 x 2 in. corrugations.
These come in the following thicknesses: (in.) 0.111, 0.140, 0.170, 0.188, 0.218, 0.249, 0.280.
This info per the AISI Handbook of Steel Drainage and Highway Construction Products.
This product is different from a corrugated steel pipe arch (cspa), in that it is created from formed plates and bolted or rivited together. Whereas a cspa is created by "squashing" a circular rolled culvert pipe into the specified form.
Note that the thickness is an important piece of information to gather on these large diameter pipes when doing a topo on a job where the existing pipe may either be extended, or receive a change in depth of cover.
CMP
Corrugated Metal Pipe
If the client insists on a more accurate description, I'm in trouble. Never happened to me, yet.
I'd code it A/S (arch/span) CMP #XXX, with XXX being the numbered field book entry or photograph. In the book I'd enter the measured dimensions.
I am in more trouble, have always known of that as "tinhorn"
😉
5'X7' OVAL CMP

7' x 5' SSPA
That is, if you want the end user to know that you know what you're talking about.
