Hunterdon County to launch $2M slurry seal road program Sept. 2; officials warn of delays as schools reopen
Impacted Municipalities: Clinton Township, Raritan Township, Delaware Township, West Amwell Township, and Stockton Borough
HUNTERDON COUNTY, N.J. – The Hunterdon County Department of Public Works and the Board of County Commissioners announced that the county’s 2025 Slurry Seal Pavement Preservation Program will officially begin Tuesday, Sept. 2.
Work will start on County Route 523, from the Dvoor Route 12 Circle to Stockton Borough. Once that segment is complete, crews will immediately begin the next phase covering County Routes 626, 641 and 633 in the Annandale area.
The $2 million roadway investment is fully funded within the county’s budget with no new debt issued. Officials said the program uses microsurfacing — also known as slurry seal — a proven and environmentally sound method for maintaining road surfaces. The treatment extends pavement life, increases skid resistance, and provides a refreshed, uniform appearance, all while reducing long-term maintenance costs.
“Micro-surfacing is one of the most efficient tools we have to preserve our roads before they require full reconstruction,” said Commissioner Deputy Director Shaun C. Van Doren. “It’s a smart investment that saves taxpayer dollars in the long run while keeping our infrastructure strong and dependable.”
County officials noted that the work begins as schools across Hunterdon County reopen, and they outlined scheduling details:
- Hunterdon Central Regional High School, South Hunterdon sending districts, Readington and East Amwell Township schools will start classes on Tuesday, Sept. 2.
- Delaware Township schools will open Wednesday, Sept. 3.
- Flemington-Raritan schools will begin Thursday, Sept. 4.
- North Hunterdon and Clinton Township schools are already in session.
The Department of Public Works said it has coordinated directly with school transportation managers to understand bus schedules and shared that information with the slurry seal contractor. Individual school administrators will also be contacted to ensure full awareness of the project.
Residents and commuters should expect traffic delays in the affected areas. Alternating traffic methods will be in place for the duration of the work, and motorists are encouraged to plan alternate routes where possible.
“With nearly 243 county roads under our jurisdiction, continuing to make smart, sustainable investments like slurry seal is essential,” Van Doren said. “We appreciate the public’s patience and cooperation as we work to keep our roads safe, efficient, and long-lasting.”
