Route Typologies - List

Outline List (Part 1)

The architectural/geographical/cultural resources that are the focus of this nomenclature and discussion are predominantly "historical," i.e., more than 50 years of age. A better absolute closing date is World War II, which ended many architectural, structural and technological trends.

Example types and subtypes are linked to part of an online topographic map collection at TopoZone and will call up a topographic map in a new window showing the place.
