For this interesting assignment, the pocket-etymologist came up in me, aided by a year of classes in Latin, many moons ago.
The word "transport" originates - like most English words - from Latin and is derived from:
"trans" which means "across" and
"portare" which means "to carry"
That gave me the direction for this month's submission.
The bridge on this shot is a train-bridge across which the "skytrains" - as they are called here - rush commuters. It's a lovely ride with a great view from inside and interestingly lit at night.
Tried to add compositional texture by including other forms of transportation in the image, hence the boat and, on the left side, the neighboring bridge for car traffic. Waited for a while to get an airplane in the shot as well, but no luck

Bit of lens-flare at the closest pillars, which I could've cloned out for this small-sized image, but it didn't look well on the full-sized one, so I left it in there).
