Pennsylvania Turnpike

PA turnpike logoKnown as America’s First Superhighway, the Pennsylvania Turnpike officially opened to traffic on Oct. 1, 1940. It was the first roadway of its kind to use modern technology to design and construct a major highway in the United States allowing for nonstop travel. Today, 550 miles of toll road operate under the direction of a five-member PA Turnpike Commission (PTC) whose mission is to operate a safe, reliable, customer-valued toll road system that supports national mobility and commerce. The roadway includes five tunnels, 12 major bridges, 75 fare collection facilities, 28 maintenance facilities and 17 service plazas. As parts of the roadway reach 80 years old, total reconstruction and widening has been part of the capital plan. To date more than 133 miles of roadway have been reconstructed using the best technology available. The PA Turnpike Commission plans to continue being a leader in transportation and innovation.
