Up until late 1988, Route 33 westbound ran underneath US 130, then merged with 130's southbound lanes. This was because Route 33 ran parallel to Pennsylvania Railroad (PRR) at that point, requiring a massive concrete overpass. (Route 33 eastbound also ascended the bridge approach about halfway before branching off like an exit ramp—a sign with flashing lights read "Hightstown, Shore Points" at the fork.) PRR abandoned the Hightstown–Windsor segment in 1967, reducing the importance of the hulking bridge. NJDOT eventually demolished the crumbling structure in 1989, with its approaches flattened to grade. Route 33 now meets US 130 at the north end of the multiplex with a traffic signal.
