Feb. 8, 1983 BIKEWAYS -41_ (a) Designate the type and character of vehicles or In general, bikeways that are part of the roadway or other modes of travel which may be operated on a bicycle shoulder, will not necessitate any additional erosion control lane or bicycle way, provided that the operation of such efforts other than those provided in normal road con- vehicle or other mode of travel is not inconsistent with the struction. An exception to this would be the construction safe use and enjoyment of the bicycle lane or bicycle way of a rural roadway with a bikeway on the roadway by bicycle traffic. shoulder.
