Expressways and highways

Locals refer to the interstates fanning out from downtown Pittsburgh as the "parkways." Interstate 376 is both the "parkway east" connecting to Interstate 76 (Pennsylvania Turnpike) and the "parkway west" connecting to Interstate 79, the Pittsburgh International Airport, the Ohio end of the Turnpike and Interstate 80. The "parkway north" is Interstate 279 connecting to I-79. The "crosstown" is Interstate 579 allowing access to the heart of downtown, the Liberty Tunnels and the PPG Paints Arena. The 45-mile-long and 70-mile-long expressway sections of Pennsylvania Route 28 and U.S. Route 22 also carry traffic from downtown to the northeast and western suburbs, respectively. Interstate 70, 79 and 76 (the Turnpike) roughly form a triangular-shaped "beltway" with Interstate 68 and 80 within the media market's northern and southern limits. Turnpike spurs such as the Mon–Fayette Expressway, Pennsylvania Route 576 and Route 66 also help traffic flow. The non-expressway Pittsburgh/Allegheny County Belt System serves navigation in the region.
