 The portion of US 22 between Phillipsburg and Somerville roughly follows the alignment of the Jersey Turnpike , which was chartered in 1806 . What became US 22 across New Jersey was originally designated as pre @-@ 1927 Route 9 in 1916 , a route that ran from Phillipsburg east to Elizabeth . When the U.S. Highway System was established in 1926 , US 22 was designated through New Jersey from the Northampton Street Bridge in <unk> and followed Route 9 east to US 1 / 9 in Elizabeth . A year later , in the 1927 New Jersey state highway renumbering , Route 9 was replaced by Route 28 , which itself was rerouted to continue to the Goethals Bridge . As a result , the alignment of US 22 in Elizabeth was designated Route 27 @-@ 28 Link . By 1941 , US 22 underwent two significant realignments within the state . In Phillipsburg , the route was moved from Route 28 to follow its current alignment on what was Route 24 between the Easton @-@ Phillipsburg Toll Bridge and present @-@ day Route 57 ( then a part of Route 24 ) and Route 24 @-@ 28 Link between there and Route 28 . The approach to the Easton @-@ Phillipsburg Toll Bridge , which opened in 1938 , had been planned to be designated Route 24N , but instead became a part of Route 24 . With the realignment of US 22 in Phillipsburg , the old alignment was designated as US 22 Alternate ( now Route 122 ) . In addition , US 22 was moved off from Route 28 east of Bridgewater Township to follow Route 28 @-@ 29 Link and Route 29 to Newark ; Route 29 had been legislated in the 1927 renumbering while Route 28 @-@ 29 Link was legislated in 1938 .
