A section of highway has vertical and horizontal curves with the
same design speed. A vertical sag curve on this highway connects a
+1% and a +3% grade and is 420 ft long. If a horizontal curve on
this highway is on a two-lane section with 12ft lanes, has a
central angle of 37 degrees, and has a superelevation of 6%, what
is the length of the horizontal curve?
