grades within the intersection area for stop conditions are shown in Figs. 2.32 and 2.33.
The grade outside the intersection area is controlled by the design speed of the crossroad.
Normal design practices can be used outside the intersection area with the only
restriction on the profile being the sight distance required as discussed above.
Grade breaks are permitted at the edge of the mainline pavement for a stop condition.
If these grade breaks exceed the limits given in note 3 of Fig. 2.32, they should
be treated according to note 3 of Fig. 2.33. Several examples are shown in Fig. 2.33 of
the use of grade breaks or short vertical curves adjacent to the edge of through pavement.
Signalized intersections require a more sophisticated crossroad profile. Whenever
possible, roadway profiles through the intersection area of a signalized intersection
should be designed to meet the design speed of the roads. Grade breaks at signalized
