Route 206 Closure for Culvert Repair Begins This Week in Princeton

New Jersey Department of Transportation (NJDOT) officials today announced the rescheduled closure and detour of Route 206 in both directions begins tomorrow night as a priority culvert replacement project advances in Princeton.
Beginning at 9pm tomorrow, Thursday, November 15, until 6am Wednesday November 21, NJDOT’s contractor Marbro Inc., is scheduled to close Route 206 in both directions between Hillside Avenue and Arreton Road to excavate, demolish, and replace a culvert over a branch of Stony Brook. The culvert replacement was originally scheduled to begin last week.

In the fall of 2017, a scheduled inspection, found the 14-foot culvert, built more than 100 years ago, was in need of replacement. Temporary steel plates were installed and paved over until a new culvert could be manufactured and prepared for installation. The $1.9 million state-funded culvert replacement project is replacing the culvert that had missing concrete, scour within the culvert, and was causing ponding on the roadway. The project in expected to be completed in spring 2019. NJDOT will be providing updates as the culvert replacement work advances. The following detours will be in place until the work is complete.
