Like the other counties mentioned earlier, Alleghany County, PA (containing Pittsburgh) is another poor TIGER specimen. To complicate things is the hilly environment which narrows streets and also streets in TIGER which are actually pedestrian walkways or, more often, staircases.

I began my Pittsburgh TIGER cleanup on the south slope near Mount Washington, and now on the north slope (Spring Hill, East Allegheny, Millvale). In the interval were edits on the Hill District from the Civic Arena east to Herron Hill, and the Allegheny waterfront between 16th and 40th Streets.
