About 'Pittsburgh, PA, USA'
Pittsburgh is the second-largest city in the US Commonwealth of Pennsylvania and the county seat of Allegheny County. Pittsburgh is known colloquially as 'The City of Bridges' and 'The Steel City' for its many bridges and former steel manufacturing base.. The characteristic shape of Pittsburgh's central business district is a triangular tract carved by the confluence of the Allegheny and Monongahela rivers, which form the Ohio River. Regionally, it anchors the largest urban area of Appalachia and the Ohio River Valley, and nationally, it is the 22nd-largest urban area in the United States. The city features 151 high-rise buildings, 446 bridges, two inclined railways, and a pre-revolutionary fortification. Downtown Pittsburgh retains substantial economic influence, ranking at 25th in the nation for jobs within the urban core and 6th in job density. The population of the city in 2010 was 305,704, while that of the seven-county metropolitan area stood at 2,356,285. | |
