8) Suppose a new sign structure is being installed on the right side of the EB direction of a freeway. The new sign support falls within the clear zone and must be protected by a longitudinal steel beam guardrail. If the far edge of the sign support is located 27 ft from the edge of the right travel lane, and the freeway has a design speed of 55 mph with an ADT of 7,000 vehicles per day, determine the length of guardrail required up to the new sign structure. Assume the freeway is divided by a concrete median barrier and only EB traffic needs to be considered, and assume the guardrail will be placed 9 ft from the edge of the right travel lane.
