COST AND BENEFIT PROBLEMS OF HIGHWAY SHOULDERS
CONSTRUCTION RECORDS DO NOT SHOW THE TOTAL AMOUNT OF WORK CHARGEABLE TO HIGHWAY SHOULDERS. THE EXTENT TO WHICH COSTS ARE CHARGEABLE TO SHOULDERS SHOULD BE COVERED BY A STANDARD DEFINITION. SHOULDER WIDTHS VARY BECAUSE OF THE VALUE OF BENEFITS OBTAINED. THE SHOULDER PROBLEM INVOLVED IN REHABILITATING WIDENING OLD PAVEMENTS ON NARROW RIGHTS-OF-WAY CAN BE QUITE EXPENSIVE. SHOULDERS GIVE LATERAL SUPPORT TO THE SURFACE AND BASE. ADDITIONAL WIDTH MAY BE NEEDED FOR EMERGENCY USE AND ACCOMMODATION OF STOPPING OR STOPPED VEHICLES. STABILIZATION AND STRENGTHENING MUST BE PROVIDED WHERE NECESSARY. COSTS CONTINUE TO MOUNT, BUT SO DO SUCH BENEFITS AS BETTER DRAINAGE, ADDED TRAFFIC CAPACITY, FEWER ACCIDENTS, AND TIME SAVINGS.
