You can still access Hopewell Borough from Lawrence by taking Carter Road to Princeton Avenue.

Orchard Road between Opossum Road and Autumn Lane is scheduled to be closed to all traffic starting Monday, April 8, and is expected to reopen in July. The road will be closed for bridge repairs. The posted detour route will use Orchard Road, Route 206, Sunset Road and Burnt Hill Road. The Rock Brook School can be accessed from the Opossum Road end of the closure.


  1. Clearly no communication between the town and county. There are at least 5 bridge closures in this area that make getting anywhere around Montgomery/Princeton/Hopewell a nightmare! Utterly ridiculous.

  2. Then why is the road already closed at 8:30 am and still closed at 3 pm if the hours are 9 to 2 pm? Getting to work and getting home is now an impossible task!
