Route 167 originates as a part of New Jersey Route 4 from
Absecon to
Rahway, designated in the 1920s. The route remained intact for several years, receiving the co-designation of US 9 in 1926, when the nationwide system was assigned. In 1927, the
New Jersey State Highway Department had a
statewide state highway renumbering, extending Route 4 in both directions. The two routes remained intact until Route 4 was truncated to
Bergen County during the
1953 state highway renumbering.) The roadway itself remained until construction of the Garden State Parkway's tenth section from
New Jersey Route 43 in Absecon to Dover Road in 1954. In August of that year, a bridge over the
Mullica River for the Parkway, onto which US 9 was realigned, was completed, replacing the alignment over the old structure. During construction, Route 4 and US 9 were realigned onto a temporary alignment to the older structure, while the old one remained unnumbered. in Port Republic Upon the realignment of US 9, the State Highway Department renumbered the former alignment as Route 167. Route 167 now continued along the former alignment, using the iron truss bridge built in 1917 for Route 4 to the intersection with US 9 in Bass River Township. The old iron truss bridge lasted several years after the realignment, lasting past 1960. The truss bridge was dismantled in 1962, and sold to the state of
Virginia and the
National Park Service for the
National Wildlife Refuge. The route remained intact for a couple decades, with a gap in the highway. The State Highway Department registered the alignment of Route 167 in 1969 as long, although there was a gap in the roadway. The route's northern half from the
Mullica River, constructed in 1926 as part of Route 4, was dismantled in 1984 for
Edwin B. Forsythe National Wildlife Refuge. As of 2007, Route 167 is unsigned, running from US 9 in Port Republic to the bank of the Garden State Parkway at the Mullica River Bridge on its south side and from US 9 to a gate on the north side. The straight line diagrams also mention the length of the roadway being long, although only is still accessible roadway. ==Major intersections==
