New Jersey State Highway Routes

Route 170 was a short, 0.79-mile (1.27 km) long state highway in Burlington County, New Jersey. The route was a former alignment of U.S. Route 206 and New Jersey Route 39 in the downtown portions of Mansfield Township and Columbus. Route 170 began at an intersection with U.S. Route 206 in Mansfield Township, headed northward along Atlantic Avenue and New York Avenue in Columbus before merging with U.S. Route 206 at a wye connection further north.

The highway was assigned as part of Route 39 in the state highway renumbering in 1927. The route remained intact, receiving a concurrency through the two communities when U.S. Route 206 was assigned in the mid-1930s. The two routes remained intact until the state highway renumbering on January 1, 1953, when Route 39 was decommissioned in favor of just U.S. Route 206. The highway was bypassed in 1957, with Route 206 heading to the outside of the communities. The original alignment became Route 170, and lasted until 1986, when it was removed from the state maintenance. The state turned the alignment over to Burlington County, who re-designated it as County Route 690.

Burlington County Route 690 (also known as Atlantic Avenue) begins at an wye intersection with U.S. Route 206 in the community of Mansfield Township. The route heads northward, intersecting with the southbound portion of the road. Route 690 becomes surrounded by several residential homes for a distance, becoming more commercial as the route heads northward, entering the community of Columbus. Route 690 continues through the business district of Columbus, intersecting with County Route 543 (Main Street) in the center of the community.
