I-95 was planned to connect to run approximately along the route of US
206, through some extremely wealthy suburban communities (including
Princeton).  The people who lived there would not hear of it, so I-95
ended historically "left" the Turnpike just north of the Brunswicks;
it picks up again on the north side of Trenton.

Current plans are for I-95 to join the PA Turnpike near where they
currently fail to intersect, and follow that road (currently I-276)
across the Delaware River to the NJ Turnpike.  The rest of the
Delaware Expressway would then pick up an I-x95 designation.
Pennsylvania has dragged its feet for the past decade in constructing
the necessary interchange.
