Strait talk about narrow and wide gates

Matthew 7:13 Enter ye in at the strait gate: for wide is the gate, and broad is the way, that leadeth to destruction, and many there be which go in thereat: [kjv]

εισελθατε δια της στενης πυλης οτι πλατεια και ευρυχωρος η οδος η απαγουσα εις την απωλειαν και πολλοι εισιν οι εισερχομενοι δι αυτης [gnt]

7:14 Because strait is the gate, and narrow is the way, which leadeth unto life, and few there be that find it. [kjv]

οτι στενη η πυλη και τεθλιμμενη η οδος η απαγουσα εις την ζωην και ολιγοι εισιν οι ευρισκοντες αυτην [gnt]

In Matthew 7, Jesus talks of the straight and wide gates. What exactly is a "strait" gate? Does the "gate" part of the "wide" or "broad" actually exist? The word is added in some Greek manuscripts.
The ancient Greek word "πλατύς" ≈ "wide, flat" and is related to the English word "flat".

Wessex: Ganged enn (sic) þurh þaet narewe geat. for-þan þaet geat ys swiðe wid. & se weig is swiðe rum þe to for-spillendnysse gelaet. & swiðe manige synde þe þurh þane weig fareð.

Gothic: inngaggaith thairh aggwu daur, unte braid daur jah rums wigs sa brigganda in fralustai, jah managai sind thai inngaleithandans thairh thata.

Luther: Gehet ein durch die enge Pforte! Denn die Pforte ist weit, und der Weg ist breit, der zur Verdammnis abführet; und ihrer sind viel, die darauf wandeln.

Some relevant words here are the following.

"strait"
"gate"
"wide" (previous verse)
"broad"
"way"
"narrow" (next verse)

At this point, the other words appear to be clear as usually translated without further clarification.

How did the huge Persian army get across?
For the Persian army to get from Asia Minor (Turkey) to Greek, it was necessary to cross over. The best places to do this is called the Dardanelles or the Bosporus (literally, "cow crossing" in folk etymology). These crossing points separate the Aegean Sea and the Black Sea.
