15.7.4 Cross Section and Cross Slopes

Superelevation rates, as related to curvature and design speed of the ramp or direct connector, should be based on values seen in
Chapter 4, Table 4-6
or
Table 4-7
The cross section of a ramp or direct connector is a function of the following variables:
  • Number of lanes determined by traffic volume;
  • Minimum lane and shoulder width, see
    Table 15-4
    ;
  • Lane balance; and
  • Where traffic volumes require two lanes merging onto a freeway, adequate weaving distance must be provided.
