It actually runs southwest to northeast. Since I usually take the 405 which runs "north" from San Diego, (in spite of the fact that parts of it are due east/west), and it crosses the 55 at a right angle, it is convenient for me to call Santa Ana and Costa Mesa "north" of the 55.
CalTrans designates the north/southness and east/westhness of the designated route based on whether the termination points are more north/south, or east/west.
Life is too short to quibble over insignificant "flaws".
