To some it’s everything across the Alleghney River from downtown. There is more to it then that. The North Shore is the area between the  Rachel Carson Bridge, or  Ninth Street Bridge to the Rivers Casino. It’s a new area bulldozed in the late 1990s/2000 to build stadiums and ball parks. Its the bustling place on game day. None game days its filled with chain resturants and river trails. Its a river life The Northside is north of the highway. Its filled with neighborhoods and mom and pop resturants. Quit parks and beuitiful old houses .
