It's Called "Counterflow!"

When lanes typically reserved for traffic moving in opposite directions are re-routed for travel in the same direction, that's "counterflow." More surprising than the practice is that a term has been coined to describe it. It seems a bit odd that they would choose a word to describe it...and such a clunky one at that. How might one describe the institution of counterflow? "Counterflow measures have been initiatied [,Captain]!" Or "The southbound side of I-75 is now counterflowing to the north." Clunky, I say!

See the Wikipedia entry on the subject for a list of cities where counterflow measures have been adopted or planned!
