Pittsburgh - Geography

Geography

According to the United States Census Bureau, Pittsburgh has a total area of 58.3 square miles (151 km2), of which 55.6 square miles (144 km2) is land and 2.8 square miles (7.3 km2) is water. The total area is 4.75% water.

The city is on the Allegheny Plateau, where the confluence of the Allegheny River from the northeast and Monongahela River from the southeast form the Ohio River. The Downtown area between the rivers is known as the Golden Triangle, and the site at the actual convergence, which is occupied by Point State Park, is referred to simply as "the Point." In addition to the downtown Golden Triangle, the city extends northeast to include the Oakland and Shadyside sections, which are home to the University of Pittsburgh, Carnegie Mellon University, Carnegie Museum and Library, and many other educational, medical, and cultural institutions.

Many of the city's neighborhoods are steeply sloped, with two-lane roads. The names of more than a quarter of Pittsburgh's neighborhoods make reference to "hills," "heights," or other indicators of topographical complexity.

This topography is often used for physical activity. The city has some 712 sets of stairs, comprising 44,645 treads and 24,090 vertical feet for pedestrians to traverse its many hills. There are hundreds of 'paper streets' composed entirely of stairs and many other steep streets with stairs for sidewalks. Many provide views of the Pittsburgh area.

The city has established bike and walking trails along its riverfronts and hollows, but steep hills and variable weather can make biking challenging. However, the city is connected to downtown Washington, D.C. (some 245 miles (394 km) away) by a continuous bike/running trail through the Alleghenies and along the Potomac Valley, known as the Great Allegheny Passage and Chesapeake and Ohio Canal Towpath.
