Route 629 will be closed for 4-6 weeks in late summer or early fall 2018 for Round Valley construction projects
Posted Date: 9/5/2018

As may be aware, NJWSA will be undertaking a series of large construction projects at Round Valley over the next two to three years. Two of the projects will require temporary closure of the section of Route 629 that parallels the reservoir, between Old Mountain Road and the boat launch area. A map showing the area to be closed is attached.

The first project that will require closure of the road is expected to occur in late summer – fall 2018 and will close the road for 4-6 weeks. The second project is scheduled for spring 2019 and will close the road for 6-8 months. These timelines and closure periods may change as construction plans evolve. We will provide notification of exact closure dates when they are available via email.
