2. A forward tangent of +6% was designed to intersect a back tangent of -3% at a proposed underpass along N. Bacalso Avenue so as to maintain a minimum clearance allowed under a bridge which crosses perpendicular to the underpass. A 200m. curve lies on the side of the back tangent while a 100m. curve lies on the side of the forward tangent. The stationing and elevation of the grade intersection is 12 + 530.20 and 100m. respectively. The center line of bridge falls at station 12 + 575.20. The elevation of the underside of the bridge is 117.48m. a.) Determine the clearance of the bridge at the left side if it has a width of 10m. b.) Determine the clearance of the bridge at the right side. c.) Determine the clearance of the bridge at the center of the bridge.
