The correct pronunciation is your option 2.

I vote for why th also.

It's "with" as far as I can tell.

It also appears to be a typo or alternative spelling for for "withe" or just "with".  Is this an document you are referencing?

fcsuper,

That's a different word.  Wythe County, Va is indeed pronounced with.  The word JAE is interested in is only used for a leaf of masonry, and is pronounced why th.  One of those words the layman (and probably the mechanical engineer) never encounters.

JAE,

Was that a haiku?

DaveAtkins,

Not intentionally.  I'm German in background - not Japanese.

Ai'm a keepin' my wythe with a with like a width and don't asketh me whyth.

hokie,

I left the link for all of it's references, not just the first one.   The last entry shows "same as withe".  Under withe, there are three pronounciations: two variations of with, and one with the long I sound.  These words all likely have the same origin in one way or another.  Besides that, the name of the county would come from a persons last name, which would come from that person's forefather's career.  Names do get mangled over time, but given the other references, it would appear "with" is more common pronunciation, but that both are correct.  This is all original research though, because I can't find a direct reference to the pronunciation in the context of masonry.  

Anwyays, my guess is that either pronunciation is correct, but "with" is more common.

If you are talking about masonry, it's wythe, with a LONG 'I'.  Take it from an architect with a family of stone and brick masons going back generations.  

I don't know what these other so-called references are talking about.  How do they want you to say a similarly-spelled construction term, wye connection?  'wih' connection, 'wee' connection?
  

"If you are going to walk on thin ice, you might as well dance!"

ACI-530

Width — The dimension of a member measured in the
plane of a cross section parallel to the neutral axis.

Wythe — Each continuous vertical section of a wall,
one masonry unit in thickness.

Aye-Aye,

My Wythes sound like a Y that is spelled like Wye, but looks like a width to I.

My dictionary does not list the word "wythe", but all the words beginning with "wy" are pronounded "weye"... So I go with ...
 
"w-eye-th".

Please excuse my spelling and punctuation.
