Multiple horizontal alignments can be useful for a variety of purposes. Including:

  • comparison and evaluation of different horizontal positions for an existing road.
  • creation of a road network.
  • creating independent parallel alignments such a bike path.
  • creating a culvert profile.
  • profiling of ditch grades.
  • controlling widening lanes and turnouts using an alignment.

Active Horizontal Alignment

When working in Location all windows (Plan, Profile, Cross Section, Data, and Multi-plot) implicitly reference the current horizontal alignment. When a new Location design is initiated a single alignment is created and made active. It is subsequently, possible to create additional alignments and to make them active.

NOTE: Intersections are not automatically determined. However, the MHA features make creating curb returns and other intersection features much easier.

Creating a New Horizontal Alignment

To create a horizontal alignment:

1) In the Corridor tab, select the Add button and then click on the Horizontal Alignment button.
