This trip begins by exiting Interstate 78 eastbound which runs concurrently with PA 309 southbound around the west and south sides of Allentown onto Cedar Crest Boulevard. Lehigh Valley Hospital Center, which is one of the region's two major hospitals is on the right. The trip then goes southbound on Cedar Crest Blvd which becomes PA 29 at the Interstate 78 interchange through a nice mix of upper middle class suburban neighborhoods and countryside. At the traffic signal by the McDonalds at approximately 6:00 the trip makes a left onto Chestnut Street and starts heading into Emmaus. (At that point PA 29 makes a right and leads to PA 100 a few miles away, Chestnut Street does not have a highway number.) When the trip turns off of Chestnut Street it goes under the busy Norfolk Southern Reading Line which is part of the busy Norfolk Southern rail line which connects the Ports of Elizabeth and Newark with Chicago. That same line goes through Lebanon PA on a recent prior video.
