Route Description
The Pennsylvania Turnpike runs east-west across Pennsylvania from the Ohio border in Lawrence County to the New Jersey border in Bucks County and passes through the Pittsburgh, Harrisburg, and Philadelphia areas along with farmland and woodland. The roadway crosses the Appalachian Mountains in the central part of the state and uses four tunnels. The Pennsylvania Turnpike Commission controls the highway. The commission was created in 1937 to construct, finance, operate and maintain the road. It consists of five members, including the secretary of the Pennsylvania Department of Transportation and four other members appointed by the Governor of Pennsylvania. In 2010, the roadway had an annual average daily traffic count ranging from a high of 118,000 vehicles between I-476 and Pennsylvania Route 309 (PA 309) to a low of 11,000 vehicles between the Ohio border and I-79 As part of the Interstate Highway System, the entire length of the turnpike is part of the National Highway System.

Famous quotes containing the words route and/or description:
“The route through childhood is shaped by many forces, and it differs for each of us. Our biological inheritance, the temperament with which we are born, the care we receive, our family relationships, the place where we grow up, the schools we attend, the culture in which we participate, and the historical period in which we live—all these affect the paths we take through childhood and condition the remainder of our lives.”
—Robert H. Wozniak (20th century)
“Everything to which we concede existence is a posit from the standpoint of a description of the theory-building process, and simultaneously real from the standpoint of the theory that is being built. Nor let us look down on the standpoint of the theory as make-believe; for we can never do better than occupy the standpoint of some theory or other, the best we can muster at the time.”
—Willard Van Orman Quine (b. 1908)
