The Lincoln enters Pennsylvania from Trenton, NJ across a fragile 19th-century bridge, then approaches Philadelphia on historic Roosevelt Boulevard. From Philadelphia to Lancaster it follows the 18th-century Lancaster Pike, whose mileposts still sit almost unnoticed on the shoulder. Robert E. Lee's troops marched along the Lincoln en route to the Battle of Gettysburg.

From Chambersburg to Ligonier (with the glaring exception of Breezewood), the Lincoln is a driver's road: two lanes, winding up and down hills and through small towns in which time stopped a half-century ago. Many views from 75-year-old postcards still look the same today. Further west, the route traverses some of Pittsburgh's oldest suburbs, then promenades through downtown Pittsburgh en route to nicking the West Virginia panhandle at Chester.

This second, revised and updated edition of Brian Butko's guide masterfully recounts the history of the Lincoln Highway across Pennsylvania. Those driving the road will learn the history of every significant site they pass...as well as those, like Bill's Place and the Ship Hotel, which no longer remain.

I-80 and the Pennsylvania Turnpike are two of the dullest drives in the eastern United States. Take a little extra time and follow the Lincoln Highway instead -- and do it with this readable but comprehensive guide.
