On high-speed dual carriageway roads, some maintenance tasks can only be conducted safely on the carriageway when the road is clear of passing traffic. The movement of a short length of coning and signing to change the configuration of a temporary traffic management layout during major road works which takes less than 5 minutes is a prime example.

Consideration should be given in the early stages of planning to the use of an approved Mobile Carriageway Closure technique to support the safe installation, maintenance and removal of temporary traffic management operations; see Section O11.23.

The technique may be used for temporary traffic management operations that have been planned, e.g. the installation of temporary traffic management layouts, contra-flow switch-overs, and tidal flow changeovers. It is not intended to be used to protect the scene of an incident in an emergency situation (unless the resources needed are already on site).

The following terms are used throughout this section.
