Manhole Covers Missing Nationwide -- Unhhh

[W.S.]

Particularly for Night Riders!  (No word on DC area, but . . .)

Philadelphia Streets Unsafe for Manhole Covers

Also, "Phoenix has lost more than 160 of its manhole covers and street storm
drains this year, up from 10 last year.
More than 80 drains and manhole covers have been stolen in Long Beach,
Calif., this year and at least two local car owners who drove over the open
chambers have filed claims against the city.
Starting last year, such thefts in Cleveland, Memphis, Miami and Milwaukee
have more than doubled compared with other years, although New York reports
no such increase."

This happens a lot in Central America. Down there a "Good Samaritan" will
typically place a long log into the hole so it sticks a couple feet up to
let you know there's no cover.

I just don't know if I'd rather hit a vertical log or a manhole cover????

Thankfully a lot of those suckers (at least in the VIP zones) are welded down in DC, in the name of security.

Here's another factoid: why are most manhole covers round? It makes it impossible for them to fall into the hole.

One of the guys on LaBusas.org was mentioning that this is becoming
common around Detroit.  People steal the covers and sell them for
scrap.

That's one reason.  There are others:

You don't have to orient them in a particular way to put them into
place...any rotation is fine.  Not the case with other shapes.  Save
time and time = $.

You don't have to carry them from place to place...you can roll them.

Round tends to limit stress risers in the metal.  things with sharp
corners tend to concentrate stresses at the corners, and cracks are most
likely there.  Also, round tends to cool more uniformly after casting,
which limits warpage.

Access ways tend to be pipes, which are round, so a round cover is
simpler than having a transition piece that goes from round pipe to
square (or whatever) cover.

In some cases the rough castings need to be machined to final
dimensions...and it's easier and cheaper to turn them on a lathe than to
machine them on a mill.

There are probably other good reasons too.

Learning from your mistakes is good.  Learning from someone else's
mistakes is better.

They likely save a good bit on cost due to cutting corners (literally) over
square ones without sacrificing much in the way of usable space.

Most important reason?  Because manholes are round.

And I suspect that theft is not a problem.
For you anyway...

Sorry, just too easy.--

Seems to me that if the scrap yards would stop buying them, the problem
would go away.

True but, they probably make money selling them back to the city.? :-)
