The Ben Franklin was the first road bridge south of Trenton- it opened in 1926 and was for a short time the longest span in the world. The Delair bridge was built by the PRR in 1895/1896 and was the first rail crossing into South Jersey. Before the construction of those two there were several ferries for cars and rail. The last one (Bridgeport-Chester on US-322) only shut down when the Commodore Barry opened in 1974.
The point being, travel into and across South Jersey before the advent of our current bridge and highway system was slow. Until the "good roads" movement of the early 1900s, road improvement wasn't even agreed by all to be a good reason to levy taxes or a worthy project to spend them on. Where I live in Gloucester County near the river, there are plenty of pre-revolution roadside inns all over, especially up and down King's Highway. In those days, before rail, everything moved at the pace of horse and wagon, and to reach Salem or Bridgeton from Philadelphia was a two-day trek, necessitating overnight lodging. A well preserved example just down the road from here- now a private residence, but still worth checking out:
