New Jersey State Highway 167, like many New Jersey state highways, was created when a U.S. highway (in this case, U.S. 9) was rerouted around Mullica River in 1954. The southern end is in Port Republic, New Jersey and the northern end is in Bass River, New Jersey.

Today, NJ 167 is unsigned. Several bridges are down and there are abandoned sections in the middle; a section in Port Republic has been closed since 1987 and decomissioned, so there is one large gap where previously there had been several smaller ones. The only indication that NJ 167 is a state highway is the still-existing zero mile marker.
