Repeat Problem 7-20 for an intersection of a divided four-lane major road and a two-lane minor road, if the median width on the major road is 12 ft and the approach grade on the minor road is 3%.

What will be an ideal response?




For practical purposes, this may be rounded to 730 ft.

This question asks for the location of the building relative to the centerline of the

outside lane of the major road. An answer is not provided for this value.

Calculating dISD is just the first part of the solution.



This is the building location relative to the inside lane. Add 48 ft (3 lane widths

and the median width) to get location relative to the outside lane. ???????????????????????????????? =

18.36 + 48 = 66.36 ????????. So the building must be located at least 66.36 feet from

the centerline of the outside lane.
