Tutorial: Creating A Divided Highway Corridor - Autodesk CIVIL3D - CIVILDESIGNCOMP 2007 SLM CD Tutorials Manual

NOTE Notice that at station 7+50, the lane uses the polyline as a target, and
not the feature line. When more than one target object is found at a station,
the object that is closest to the corridor baseline is used as the target.

Tutorial: Creating a Divided Highway Corridor

This tutorial demonstrates how to create a divided highway corridor. The
tutorial uses some of the subassemblies that are shipped with AutoCAD Civil
3D to create a more complex and realistic highway model.
This highway has a depressed median with a flat bottom ditch and inside
paved shoulders, two travel lanes on each side of the median, and paved
outside shoulders. The total median width between inside
edges-of-traveled-ways is 44 feet. The highway may have at-grade intersections,
so the superelevation rotation point is set to be located at the design profile
grade above the centerline of the median ditch. This creates a single consistent
cross slope across the entire roadway in superelevated areas.
For more information, see the AutoCAD Civil 3D Help topic Creating Corridors.
