The city of Allentown, Pennsylvania has been known for its diners since the early 1900s. Many highways were built to accommodate early truck traffic between manufacturing cities to distribution centers, and the concept developed to support truck and long distance travelers along these inter-city roads. Located at the intersection of several main highways (U.S. Route 22, U.S. Route 309 and U.S. Route 222), as automobile traffic along the roads increased during the 1920s and 1930s, Allentown became a popular stopover for travelers heading to New York City, Philadelphia, Harrisburg and Lancaster. Route 22 in particular, known as the "William Penn Highway," brought hungry travelers through the city on Tilghman Street before the Lehigh Valley Thruway bypass (1955) moved most long-distance road traffic north of the city. 1950's roadside sign for the Charcoal remains, in a deteriorated condition. * Chris's Family Restaurant (1992) * Dina's Diner (1940s) * Hamilton Family Restaurant (1959) * Peter Pan Diner (1956-1989) * Poodle Skirt Restaurant (1956-2001) * Queen City Diner (1970) * Sabroso Restaurant (1930s) * Tom Sawyer Diner (1962)
