 Due to opposition in Phillipsburg, New Jersey on the building of a new highway through the town, PennDOT and NJDOT decided to reroute I-78 to the south and allow U.S. 22 to remain on the limited-access highway, which, after going through a series of sharp, potentially dangerous curves in Easton and crossing the Delaware River into New Jersey, becomes an at-grade divided highway in Phillipsburg.Traffic on the Lehigh Valley Thruway is often heavy at rush hour, particularly near the PA 145 interchange.The series of sharp curves is locally known as "Cemetery Curve", and because of it, the speed limit is lowered to 45 mph at Route 248 and then lowered to 35 mph around the sharpest part of the curves.
