NJ 73 is a north/south route in the suburbs of Philadelphia. It begins at Black Horse Pike (US 322) in Folsom and extends to the Tacony-Palmyra Bridge, which crosses the Delaware River to Philadelphia. It becomes PA 73 at the state line. At its southern end, NJ 73 is a two-lane undivided road, but it widens to four lanes and then becomes a divided highway as it works its way north. Since the Ben Franklin Bridge (I-676/US 30) and the Betsy Ross Bridge (NJ 90) have no direct highway connection to the New Jersey Turnpike (NJ 700), motorists bound for Philadelphia from the north generally use NJ 73 to access one of these two bridges.
