It's no "Surrender Dorothy."
First, this is not a safe practice. CSX doesn't want you out on its bridge, especially in the dark, spray painting. Second, if you fall, you're in big trouble. That said:

Some context... Surrender Dorothy

WASHINGTON D.C. — Who did it?
Who played the part of the Wicked Witch of the West and was the first in the early 1970s to spray paint the message "Surrender Dorothy" on an overpass on the Washington D.C. Beltway right where the Mormon Temple comes into view? The mystery is now, at least partially, solved.
Christine Mulligan of Germantown, Md., wrote to "Answer Man" John Kelly at The Washington Post last month to see if he knew the orgin of the painted prank.
He didn't — at first.

Several people responded to The Washington Post's Answer Man's request for information.
