同时注意到：

March 15, 2011 - When Tampa International Airport (TPA) shut down its primary runway in early January to repaint the numeric designators at each end, and change the taxiway signage, the reason for the closure set off a maelstrom of press coverage. As a result of the movement of the magnetic north pole, runway 18R/36L no longer aligned along the 180-degree/0-degree north-south axis. When the runway reopened, it had been repainted 19R/1L to more accurately reflect its magnetic directions. More than 140 signs and panels had to be changed, as well as the painted numerals on the runways. Later in the month, a lesser-used, parallel runway and an east-west runway were also changed.
