Route 31 southbound ramps at Center Street in Clinton to close Friday through Monday for watermain work
CLINTON, N.J. (Hunterdon County) — The Route 31 southbound ramps to and from Center Street in Clinton will be closed from Friday afternoon through Monday morning to allow for watermain installation as part of a major roadway reconstruction project, the New Jersey Department of Transportation announced.
The closures will begin at 1 p.m. Friday, December 12, and remain in place until 5 a.m. Monday, December 15. Access to businesses on Center Street will be maintained throughout the work period.
During the closure, the following detours will be in place:
Route 31 southbound ramp to Center Street detour:
• Motorists will be directed to turn right onto Grayrock Road, before Center Street.
• Turn left onto Center Street.
Center Street ramp to Route 31 southbound detour:

• Turn right onto Route 31 southbound.
The work is part of the $24.8 million federally funded Route 31, I-78/Route 22 to Grayrock Road pavement reconstruction project, which will replace deteriorated concrete pavement with full-depth asphalt. The project also includes realigning the intersection of Center Street eastbound and Route 31 southbound to improve sight distance, extending the acceleration lane from I-78/Route 22 westbound to Route 31 northbound, drainage upgrades, guiderail replacement, new lighting, overhead sign installation and bridge deck repairs.
The project is expected to be completed by fall 2026.
DOT officials said the schedule may change due to weather or other unforeseen factors. Motorists are encouraged to check www.511nj.org for real-time travel updates and construction information.
