Using Alignment and Profile Targets to Model a Roadside Swale

The previous chapter included an example where the road lane used an alignment and profile target to add a variable width and elevation to the edge of traveled way.

This chapter deals with a roadside swale that follows a variable horizontal alignment, as well as a vertical profile that doesn’t follow the centerline of the road. This happens frequently when existing culvert crossings must be met or when you have different slope requirements for the roadside swale.

Corridor Utilities

To create an alignment and profile for the swale, you’ll take advantage of some of the corridor utilities found in the Launch Pad panel (Figure 10-2) by selecting the corridor.
