Although the alignment is registered by the New Jersey Department of Transportation as 2.76 miles (4.44 km) highway, the amount of roadway is considerably shorter.

When the bridge was finished, US 9 was realigned off the roadway and the prior alignment became Route 167 during the New Jersey state highway renumbering.

The route was split twice since 1953, first by the removal of the old Mullica River bridge in 1962 as part of a sale to the National Park Service for a refuge in Virginia, then the northern portion was dismantled except for a 0.12-mile-long (0.19 km) alignment for a wetland mitigation project.

[1] After a 1.99-mile (3.20 km) gap in the roadway, which consists of a former bridge over the Mullica River dismantled and moved to Virginia, bridges removed for wetlands mitigation in the marshes just north, and the orphaned roads in between (which are visible from the Garden State Parkway to the west), Route 167 resurfaces in Bass River Township as a short dead-end street only approximately 800 ft (0.24 km) long, serving only a few homes.

[6]) 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.

[6] The route, originally 55 feet (17 m) wide, was shortened during the construction of the new alignments, which also involved taking homes and properties from the highway.

The State Highway Department registered the alignment of Route 167 in 1969 as 2.64 miles (4.25 km) long, although there was a gap in the roadway.
