PRINCETON — The closure of Route 206 originally scheduled for last week is a go for Thursday night, according to the New Jersey Department of Transportation.

The road will close in both directions at 9 p.m. between Hillside Avenue and Arreton Road, just south of Princeton Airport in order to excavate, demolish and replace a 14-foot culvert over a branch of Stony Brook, according to a press release by the DOT.

The $1.9 million project should be complete by 6 a.m. on Nov. 21.

The DOT said that concrete was found missing from the 100-year-old culvert during an inspection in the fall of 2017. The inspection also revealed scour, or erosion inside the culvert helping to create ponding on the road.

Temporary steel plates were put in and paved over while a new culvert was created.

Route 206 carries both car and truck traffic between Route 295 (the former Route 95) and the Somerville Circle.

The DOT has suggested separate detours for passenger vehicles and trucks. A longer detour is in place for trucks using Route 31 to avoid the side streets around the closure points.
