Stereogram 4. Highway route location through a suburban area. Recent aerial 
vertical photography of suitable scale, which includes all new developments in 
the suburban area, and full utilization of the principles of photographic inter- 
pretation enable highway engineers to determine routes which are least detri- 
mental to existing land uses. The best route will cause the least property 
Severance damages, will fit the topography and surroundings, and will cross the 
existing roads and principal drainageways at nearly normal angles. The inter- 
relationships between land use, property lines, existing streets and roads, 
and the new highway are all visualized and evaluated while the route is located. 
  
Stereogram 5. Highway route between residential and transportation-industrial 
areas. In such a location, this possible highway route between a residential 
and a transportation-industrial area, takes advantage of marginal lands to the 
benefit of all concerned.
