It’s the city of rivers and bridges

You don't fit here if your most secret, irrational fear is crossing bridges. A drive to Mount Washington, a trip to the supermarket, your commute, or even a visit to the ballgame all require crossing some bridge. Pittsburgh boasts more bridges than almost any other city in the world: black railway trestles, spans with soaring steel arches, and concrete motorways spanning any of a number of rivers. Suspension spans, antique box and girders, trussed arches and cantilevers abound throughout the city's bridgework.

Go to the summit of Mount Washington to see a bird's-eye view of the city, including the skyscrapers, new sports stadiums, and rivers making their way into the hills. Then add up the bridges: On a clear day, there are at least 19, ranging from the magnificent arch over the Ohio at McKees Rocks to the "Three Sisters" — virtually identical eye-bar suspension bridges connecting downtown with the North Side — to the Smithfield Street Bridge, a dazzling blue wave rolling across the Monongahela.

Pittsburgh boasts that it has more spans than any other city in the world, save Venice, Italy, with 1,945 bridges in Allegheny County and 377 bridges in the city proper. There is an international bridge conference is held here each year. For $70, you can even go on the Landmarks Foundation's yearly cruise to see river bridges from below, along with a lesson on how they were created.
