Prob. 3. A forward tangent of +6% was designed to intersect a back tangent of -3% at a proposed underpass along Bonifacio St. 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 a 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 underside of the bridge is 117.48 m. Determine the minimum clearance of the bridge if it has a width of 10 m.

A horizontal curve on Texas Highway 83 (Tx83) comprises of a two-lane rural highway with a lane width of 12 ft. and superelevation of 8%. The posted speed limit is 50 mph. along a 0.5-mile section of highway, both a horizontal and vertical curve exists. The vertical curve has an initial grade of -2.00% and a final grade of +4.00%. The PVI is at station 156+40. A driver traveling eastbound strikes a stationary roadway object. The daytime crash results in a fatality and is being investigated for safe design speed. Evaluate and comment on the roadway design.
An equal tangent vertical curve is to be constructed between grades of -2.0% and +1.0 %. The PVI is at station 11 +000.00 and at elevation 420 m. Due a street crossing the roadway, the elevation of the roadway at station 11 +071.00 must be at 421.5 m. Design the curve. (what is the curve length?)
Two tangents intersect at V with back tangent having a grade of -4.5% and forward tangent of 5.5%. A 200 m curve lies on the side of PC and 102.5 on the other side. Stationing of V is at 10+538 having an elevation of 104 m. If a bridge is located above the curve, with its centerline having an elevation of 118.5 m and stationing of 10+555, with underside of the bridge located 55 cm below the given elevation, determine the height of highest vehicle it can accommodate if the bridge has a width of 12 m.
An equal-tangent curve connects a +1.0% and a -0.5% grade. The PVC is at station 54+24 and the PVI is at station 56+92. Is this curve long enough to provide passing sight distance for a 60-mi/r design speed? Problem 2
Q6. To help improve the safety of at-grade intersection of two roads, the intersection is being redesigned so that the E-W road will pass underneath the N-S road. Currently the vertical alignment of the E-W road consists of a crest vertical curve joining a 4% upgrade to a 3% downgrade. The existing vertical curve is 138 m long, the PVC of this curve is at station 14+47, and the elevation of the PVC is 477 m. The centerline of the N-S road is at station 15+45. Your job is to find the shortest vertical curve that provides 6.0 m of clearance between the new E-W road and the N-S road.
