New Jersey Statutes Title 27. Highways 27 § 3-3

When the work contemplated by section 27:3-1 of this title will necessitate the providing of detours over other roads, the board of chosen freeholders may pass a resolution setting forth the fact that detours are necessary, naming the roads to be used, and setting forth the amount of money necessary to put the detours in proper condition for travel and to maintain them during the necessary period. When the state is engaged in any work requiring such detours the determination of the necessary facts shall be made by the state highway commissioner.

The cost of repairing and maintaining the detours during that period may be included in and considered a part of the cost of construction, reconstruction or extraordinary repairs, and bonds or other obligations may be issued therefor in the same manner as for the construction, reconstruction or extraordinary repairs, and may be included in the same issue and as part thereof.
