The route heads northward through downtown Netcong and along the shores of Lake Musconetcong and enters Sussex County, New Jersey.

The route heads northward, intersecting with local dead-end streets deep in the forests of rural Morris County.

The roadway passes west of a park and ride lot located at an American Legion hall.

[4] The route in Netcong stayed the same for several years after the decommissioning until the Regional Plan Association proposed a freeway realignment of US 206 in 1962.

The project was to produce two outcomes: replacement of the New Jersey Transit bridge that Route 183 crosses, and the elimination of the Netcong Circle with a signalized intersection.

[8] The Netcong Circle was replaced with a temporary junction in January 2013; the permanent intersection configuration opened in August of that year.

The circle itself could not handle the 17,000 vehicles a year that use the large roadway daily, and was the site of several accidents, including 45 in 2007 alone.
