=====================================
Re: remark that elevated railways in New York and Chicago
are constructed over streets:

While this is generally true in New York (with one or two
exceptions, such as the Brighton Line of the old BMT in Brooklyn),
construction of elevated lines over streets was the exception
in Chicago outside the "Loop."  Only one of Chicago's L (not el)
lines, namely the Lake Street L, is constructed (mostly) above
a street, the others were all built along private right-of-way
through back alleys (and are thus often referred to as "Alley Ls").
Newer lines are in expressway median strips.

Aside:  the outer portion of the Lake St. L line ran at ground level
until the 1960's, when it was moved to the elevated (earthen embankment)
right-of-way of the Chicago and Northwestern Railroad, and thus
only part of the Lake St. L runs above a street.
