Also Pittsburgh Right; Streets or roads in Pittsburgh that make sudden turns yet keep the same name; note the difference between the traditional definition of Pittsburgh Left
(the act of allowing oncoming drivers at interesctions to make a left turn in front of you). For newbies to the city, this alternate meaning of Pittsburgh Left or Pittsburgh Right allows them to understand the strange topography of city streets. The differing definitions can only be understood in context:
"Follow Forbes Avenue past Carnegie Mellon down from Squirrel Hill. Be careful by CMU; Forbes takes a Pittsburgh Left (alt.) but it's still Forbes."
