SITUATION. A -3% grade meets a +5% gradenear an underpass. In order to maintain theminimum clearance allowed under the bridgeand at the same time introduce a verticaltransition curve in the grade line, it isnecessary to use a curve that lies 200-m onone side of the vertex of the straight gradeand 100-m on the other. The station of thebeginning of the curve (200-m side) is10+000 and its elevation is 228 m.If the uphill edge of the underside of thebridge is at station 10+220 and at elevation229.206 m, what is the vertical clearanceunder the bridge at this point?

Vertical clearance is generally the critical height under a structure that normally occupies the…
