A secondary channel is used to add design features like laybys and parking bays to the the side of a road or footpath. In particular this is used where the grade of the feature is different to that of the main road carriageway (for example, where a parking bay's grade falls to the primary channel) or where the feature has an upstand (small kerb) at the join with the primary channel. The secondary channel defines the shape of the design feature.

On the Secondary Channels Tools button secondary channels toolbar, click the New Secondary Channel button Add Secondary Channel button.
