(a) Whenever the Board determines, upon the basis of a structural engineering investigation, that the structure of a bridge on a highway is such that it is unsafe for vehicles over a certain weight to use such bridge, the Board shall by resolution direct the Road Commissioner to place signs at both entrances to such bridge specifying the maximum gross weight limits of any vehicle or combination of vehicles which shall be permitted to cross such bridge.
(b) Whenever the Board finds, because of rebuilding, repairing, or strengthening such bridge, that such weight limits are no longer necessary, the Board shall by resolution direct the Road Commissioner to remove such weight limit signs from the entrances to such bridge.
