Your diversion route plan must include:
- a title
- Ordinance Survey copyright
- the closure (solid line, preferably red)
- the suggested diversion route (dashed line, preferably blue)

If the proposed route involves roads which are outside of Hertfordshire or are not under Hertfordshire County Council control, you will need to obtain permission for the use of these roads. We will ask you to provide proof of permission where applicable, to progress your application.
