On the contrary.

In Nevada, especially on US Highways 93 and 95, they have in
the middle of the pavement (sometimes 2 lane, sometimes 4) an airplane
insignia facing both directions up and down the highway, with a listed
number in feet of how long the road is straight (without any turns).
Those markings are there for planes to use for landing in case of an
emergency, provided no cars are obstructing that stretch of land. I was
out just north of Coaldale NV (heads towards KHTH and Reno) when such
an incident happened. The pilot couldn't make it to TPH, and TNX is
Miliary, so he had no choice but to land on the road. Luckily, I was
off the road. He landed safely and was hauled off by ambulance. Don't
know what happened. But it is entirely possible (and legal) if you have
no choice but to land on a US Highway.

That's not contrary to what I said. You can land anywhere you want in
an emergency. We're not talking emergencies in this thread but every
day operations.



Interstate highways, are a different story. There is supposed
to be some law on the books from either Eisenhower's or Truman's
Presidency (perhaps revised later) when the Interstate system was
created. Every x amount of miles, the interstate must be in a straight
line (no turns), with no bridges OVER it, in case planes need to land
in emergency. I remember vaguely reading about this at the FBO at KVGT,
but can't remember which law mandated this.

Again, not what we're talking about. You keep bringing up emergencies
and that is not relavant to the discussion.
