Pennsylvania's new super-highway, built largely on the abandoned South Penn Railroad grades and tunnels of 55 years ago, is the longest four-lane divided highway in the United States. It is a high speed, all weather road with every latest safety feature and is deservedly popular because it is a time and money saver.
