The Purple Belt is the innermost colored belt in the system, running through downtown Pittsburgh. Unlike the other belts, it was established in 1995 in conjunction with the Pittsburgh Wayfinder System, a color-coded signage system downtown which helps tourists and locals find many of the common destinations in the city. (In the Wayfinder system, downtown destinations are colored purple. None of the other colors in that system correspond to the Belt System colors.) Thus, it uses a different style of signage than the other belts.
