By Air: Pittsburgh International Airport is the normal way in, although the area is also served by the smaller Allegheny County Airport in West Mifflin, primarily used by private and corporate airplanes. The airport is located near Robinson Township in Findlay, about 20 miles west of downtown, translating to about a $35 cab ride ($50 in rush hour traffic). Hotel shuttles and buses are also available, and can be cheaper.
By Train: Amtrak services Pittsburgh with a station Downtown at Grant and Liberty, just across the street from the Greyhound depot. Two Amtrak routes serve Pittsburgh- the Capitol Limited, which runs daily between Chicago and Washington, DC, and the Pennsylvanian, which runs daily between Pittsburgh and New York City through Philadelphia. This one is easy to manage with online travel planners.
By Car: The city proper is served by three interstate routes that spur from the triangular-shaped beltway formed by I-76 (PA Turnpike) to the north and east, I-79 to the west and I-70 to the far south. These three spurs form what locals often refer to as "parkways". As of November 2009, the Parkways West and East are signed as I-376, and the Parkway North is signed as I-279. Prior to 2009, the Parkway West's interstate highway designation terminated at I-79; however, this odd route numbering scheme has been fully corrected.
By Bus: Greyhound Bus serves Pittsburgh from a station in the new (Sept 2008) transportation centre at 11th and Liberty Downtown. Fullington Trailways also serves Pittsburgh out of the Greyhound station. Twice daily direct Service to DuBois PA, along with one daily (5AM departure) connecting service to Buffalo, NY, and Wilkes-Barre, PA. As a Greyhound alternative, you can travel to New York City by taking the 5AM Fullington departure and connecting in Wilkes-Barre with the Martz Trailways bus to NYC, for a less-crowded bus (but longer trip).
HOW TO GET AROUND PITTSBURGH
By Bus: Bus service covers much of Pittsburgh and Allegheny County and, for the most part, is reliable and clean.
By Train: Light rail (commonly referred to as "The T") connects the south side of the city to downtown and the stadiums, but doesn't connect to many other points of interest.
By Car: With a multitude of hills, valleys, Pittsburgh is an eclectic town to travel by car for even the natives. Very little is straightforward about Pittsburgh travel via car, but some constants help road warriors get by. Major highways include the Parkways East, West (both Interstate 376), and North (Interstate 279).
By Taxi: Taxis are a good (if expensive) way of dealing with Pittsburgh's spaghetti roads until you get used to them, at least within downtown and the inner areas of the city itself. However, they can be difficult to hail on the street except when Downtown and on the South Side and in Oakland. Plan to wait a while if you call one on a night or weekend. Taxis are usually widely available outside of major hotels.
By Cycle: Pittsburgh has some fine biking trails, most of which run along the rivers. However, Pittsburgh isn't so friendly to street cycling - the streets are narrow, are often very rough, and much of the city is very hilly, so unless you're an experienced urban cyclist, it's best to stick to the trails.
