Downtown surface streets are based on two distinct grid systems that parallel the [[Allegheny River|Allegheny]] and [[Monongahela River|Monongahela]] rivers.<ref name=conti>{{cite news| last = Conti| first = John| title = How a municipality is designed can create elegance or chaos| newspaper = [[Pittsburgh Tribune Review]]| date = January 22, 2012| url = http://www.pittsburghlive.com/x/pittsburghtrib/ae/museums/s_777698.html| access-date = January 22, 2012| url-status = dead| archive-url = https://archive.today/20130131075641/http://www.pittsburghlive.com/x/pittsburghtrib/ae/museums/s_777698.html| archive-date = January 31, 2013| df = mdy-all}}</ref>  These two grids intersect along Liberty Avenue, creating many unusual street intersections. Furthermore, the Allegheny grid contains numbered streets, while the Monongahela grid contains numbered avenues.  And, in fact, there are cases where these numbered roadways intersect, creating some confusion (i.e. the intersection of Liberty Avenue and 7th Street/6th Avenue).  This unusual grid pattern leads to Pittsburghers giving directions in the terms of landmarks, rather than turn-by-turn directions.<ref name=conti />
