An underpass crossing a reinforced concrete bridge along the Shaw Blvd. has downward grade of -4% meeting an upward grade of +8% at the vertex (elev. 170 m) at Sta 7 + 700, exactly underneath the center of the bridge having a width of 10 m. The required minimum clearance under the bridge is 5 m and the elevation of the bottom of the bridge is 178.1. Determine the following: a. length of the parabolic curve that shall connect the two tangents b. the stationing where a catch basin will be placed c. the elevation where a catch basin will be placed G&I: PVC Reg'd: L₁ 4/2 9₁ = -40% sta m, 5n 5m H 5m el. m AV PVI sta 7+700 ½/₂ el. 178.1 92=8% PVT el. 170m
