(WHITE TWP., NJ) Warren County’s project to reconstruct Lommason Glen Road is underway, and once completed the reopened road will be better able to withstand large storms.

This is the fifth reconstruction project on Lommason Glen Road since the July 2023 storm event that caused a state of emergency and closed several roads throughout the county.

 “I’d like to thank everyone involved with these reconstruction efforts,” Warren County Commissioner Director Jason J. Sarnoski said, adding, “The initial push to stop further damage was calculated and timely and the work being done now is truly impressive. County staff, the engineers, and the contractors have all worked together to ensure that this massive reconstruction project delivers a safer and stronger road way for the residents of Warren County.”

Sarnoski added, “This project was a lot to take on and I’m eager to see the final result.”

Following the 2023 storm, immediate work was done to close the breach south of Hemlock Lane at Bridge Structure 23073, and a retaining wall was erected that more efficiently directs water flow to and through the bridge, with a stabilized bank of cemented-in large stones on the downstream side of the bridge.

Further work upstream extended an existing retaining wall to contain water flow and protect the County’s road from undermining, and filled in a 20-foot-deep shoulder collapse that cut approximately halfway into one travel lane of the road. It required filling in with carefully chosen native stone from the creek, stabilization of the nearby existing embankment, and repaving of that segment of the road.

Work at the creek also occurred to remove many of the fallen trees that could potentially cause future problems if left undisturbed.

The design of all of the previous Lommason Glen Road projects, and the project now underway, were undertaken by Colliers Engineering and Design. Working closely with County Administration and the Department of Public Works, Colliers designed these projects to ultimately deliver the residents of Warren County a resiliently reconstructed road with improved drainage and protections against future significant storm events.

The current project encompasses approximately a half-mile of construction, which includes an initial phase of excavation of rock to allow for the installation of a continuous series of embankment stabilization structures. These include 1,200 linear feet of retaining wall supported by foundations that range from 2 feet to 5 feet deep, and approximately 1,200 linear feet of rip-rap filled gabion baskets.

Colliers and the County worked closely with the NJ Department of Environmental Protection to gain approvals for all work on Lommason Glen, ensuring that the natural environment of the stream, its surroundings, and the fish and wildlife have been protected throughout the process.

It is anticipated that Lommason Glen Road will reopen to the public in late 2025.
