DESIGN OF SHOULDERS TO PROVIDE SAFER WINTER TRAVEL

SHOULDER DESIGN ON THE HIGH SIDE OF SUPERELEVATED CURVES SHOULD PROVIDE A SLIGHT CROWN FROM THE EDGE OF THE PAVEMENT FOR THREE OR FOUR FEET AND THE REMAINDER SHOULD BE SLOPED IN THE OPPOSITE DIRECTION FROM THE SUPERELEVATION. THIS PREVENTS WATER FROM FLOWING ONTO AND ACROSS THE PAVEMENT FROM MELTING SNOW WINDROWS OR ANY OTHER SOURCE. MEDIAN STRIPS FOR DIVIDED HIGHWAYS SHOULD ALWAYS BE DEPRESSED AT LEAST ONE INCH TO THE FOOT. CHANNELIZATION ISLANDS SHOULD BE DEPRESSED BACK OF THE CURBS WHENEVER POSSIBLE SO THEY DO NOT DRAIN WATER ONTO THE PAVEMENT. THE SHOULDER AND ADJACENT AREA AT SIDE ROAD, STREET, AND OTHER ENTRANCES SHOULD BE CONSTRUCTED SO THAT WATER CANNOT FLOW ONTO THE PAVEMENT OF THE MAIN HIGHWAY. HIGHWAY SIGNS OR SIMILAR OBSTACLES SHOULD BE PLACED ON THE SLOPES WHERE THEY WILL NOT INTERFERE WITH THE ECONOMICAL, MECHANICAL MAINTENANCE OF THE SHOULDERS. IF THESE SHOULDER DESIGN FEATURES ARE FOLLOWED, THEY WILL PROVIDE SAFER WINTER TRAVEL.
