Bypasses are local detours along a specified route
that allow traffic to avoid an obstruction.
For example, if a bridge is
destroyed, is there a place nearby that will allow traffic to get around it
without major rerouting?
When a bypass is limited to a specific vehicle
type, it must be noted on the reconnaissance report. There are three types
of bypasses, easy, difficult, and impossible. Each type is represented by a
different symbol. These symbols are illustrated in Figure 1-23.
