Extracted text: At a highway interchange, a circular loop ramp is being designed with a 10% superelevation. There is 150,000 n area of land available for the circular loop (area to the outer loop boundary). The centerline radius is 37.9 ft less than the outer boundary radius. What is the likely design speed for this loop? (coefficient of side friction = 0.11) Answer:
