How do u say "west street", "fifth floor"

when you say "west street" and "fifth floor", do u silent "t" in "west" and "th" in "fifth"?

In "west street" the two "st" sounds seem to merge for me, although the one "st" that remains may be a bit longer than usual.

In "fifth floor', the "f" in "fifth" disappears, not the "th".

Often in English, if the last sound of a word is the same as the first sound of the following word, they can merge into one.

Hence weST STreet, toP Place, saMe Man etc etc
