Route 46 remains closed, detoured in both directions east of Ramseyburg Road as landslide repairs continue in Knowlton Twp.

KNOWLTON TOWNSHIP, NJ (Warren County) – Route 46 remains closed until further notice in both directions between Manunka Chunk Road/Upper Serapta Road and CR 519/Hope Bridgeville Road following a landslide in Knowlton Township.

The roadway was closed on Sunday, July 16 at around 8:30 a.m. Following torrential downpours, a flooded stream in the Beaver Brook Wildlife Management Area breeched a natural berm resulting in water and debris flowing down the side of the mountain and onto approximately a half-mile of Route 46 between Manunka Chunk Road/Upper Serapta Road and CR 519/Hope Bridgeville Road in Knowlton Township.

The berm, which is on New Jersey Department of Environmental Protection (NJDEP) property, must first be stabilized and repaired to stop the flow of water down the hill.

To begin this process, NJDOT is building a dirt road – approximately one mile in length – leading to the access point of the natural berm. After the berm is stabilized, remaining debris can be removed, damage can be further assessed, and any necessary repairs can be completed.

This is a dynamic and active situation compounded by continued rain. NJDOT crews are working around the clock with NJDEP and local authorities to carry out the necessary work as quickly as and as safely as possible. Route 46 will remain closed until further notice.

The following detours are in place:

Route 46 eastbound detour:

• Traffic wishing to use Route 46 eastbound will be directed to use I-80 eastbound

Route 46 westbound detour:

•  Traffic on Route 46 westbound will be directed to turn right on CR 519/Hope Bridgeville Road
•  Follow Hope Bridgeville Road though the town of Hope
• Take the ramp to I-80 westbound

The precise timing of the work is subject to change due to weather or other factors. Motorists are
encouraged to check NJDOT’s traffic information website for real-time travel information.
