(3) The minimum design standards for existing town bridges are as shown in the following table: (4) Bridge replacement, rehabilitation or widening is required where a bridge is either load posted or has a usable width that is less than the traveled way width. Bridge replacement or widening should be evaluated if the usable bridge width is less than the values shown in Table C. If widening of the traveled way is planned as part of the town road improvement, the usable bridge width should be compared to the approaches after they are widened to determine whether or not bridge replacement or widening should be evaluated. (5) The minimum design standards for new bridges on town roads are as shown in ch. Trans 214 .
