- Delaware uses SR-## for all state routes (e.g. SR-58)
- Generally even numbers run east-west and odd numbers run north-south
- Some Delaware routes are continuations from other neighboring state routes. e.g., SR-273, SR-896, SR-299.
Locking standard
In Delaware 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.
