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