In 2010, NJDOT began plans to move Route 23 to a new alignment through Sussex. With this project, the bridge over the Papakating Creek was replaced and a new road for the southbound lanes was built as an extension of Walling Avenue, while the original Route 23 became northbound only. The project lasted from July 2012 to November 2014.
