An underpass crossing a reinforced concrete bridge along Shaw Blvd has a symmetrical vertical curve, having a downward grade of -4% meeting an upward grade of +8% at the vertex V at elevation 70 m and stationing of 7+700, exactly underneath the center line of the bridge having a width of 10 m. If the required minimum clearance under the bridge is 5 m, and the elevation of the bottom of the bridge is 78.10 m. SHOW -( COMPLETE SOLUTION AND FIGURE ) - IN SOLVING, PLEASE USE THE SQUARED PROPERTY OF PARABOLA a) Determine the length of the vertical parabolic curve that shall connect the two tangents. b) Determine the stationing of the point a catch basin (lowest point) will be placed. c) Determine the elevation of the point where a catch basin (lowest point) will be placed.
