^a When a state highway "SPUR" route is used to connect a state highway with another state highway, a US highway, or an Interstate (i.e., when it is used as a connector/CONN route), use the first state highway column.

^b Also known as Principal Arterial - Interstate.

^c Also known as Principal Arterial - Freeway.

^d Also known as Principal Arterial - Expressway.

^e Also known as Principal Arterial.

^f Also known as Other Arterial.


For example,

  • An Interstate Business Loop classified as a Minor Arterial is a  Major Highway .
  • A US Highway classified as a Minor Arterial is a  Major Highway .
  • A US Highway Spur route classified as a Minor Arterial is a  Minor .
  • A State Highway classified as an Other Freeway is a  Freeway .
  • A State Highway classified as a Collector is a  Minor .
  • A County Route classified as a Minor Arterial is a  Minor .
  • A County Route classified as a Collector is a  PS 
  • A locally-maintained road classified as an Other Principal Arterial is a  Major Highway .
  • A locally-maintained road classified as a Collector is a  PS .

Locking standard

In Crazycaveman we have a set minimum standard for locking roads based on segment type. Any road of a certain segment type must be locked at least to the rank (level) in the chart below. Roads may be locked higher for protection and special situations (areas with construction, tricky design, frequent mistakes, imaging inaccuracies, and the like), but should not be locked lower.

A great time to implement these locks is while bringing the road types of an area into compliance with the current US road type standards (FC and highway systems). Lock the roads based on type after they've been set to current US road type standards.

Crazycaveman Minimum Locking Rank Standard
Segment Type Coastal  Urban  Rural
 Freeway  5
 Ramp  Highest Rank of Connected Segments
 Major Highway  4 3 2
 Minor Highway  3 2 Automatic
 Primary Street  2 Automatic
 Street  1
 |-|-|-|-|-|-|-|-|-| Railroad |-|-|-|-|-|-|-|-|-|  2
 • • • • Ferry • • • •   5

Note: Rural locks may be increased to Urban locks once an area can be considered "complete" (correct turn restrictions, road classified appropriately, and minimal URs)
