In this section

A Temporary Traffic Regulation Order (TTRO) or Temporary Traffic Regulation Notice (TTRN) is made when it is necessary to temporarily stop or limit vehicular and/or pedestrian traffic along the highway, including roads and rights of way, to facilitate

  • planned works and activities
  • urgent or emergency situations that are unforeseen
  • essential works including highway maintenance and improvements
  • utility works
  • works adjacent to the highway, including new developments

Organisers of events on the highway are required to follow a separate process.

Whilst not an exhaustive list, TTROs can be made for the following:

  • road closures
  • waiting restrictions/parking suspensions
  • weight restrictions
  • banned turns
  • one-way systems
  • speed limits

If you need to close a private or unadopted road, you will need to contact the land owner(s) to get their consent. We would not authorise a TTRO for private land.

Closures of footways (pavements) running adjacent to the road can be authorised by a road space booking.

Lead times and charges

Works promoters can benefit from reduced fees by:

  • giving us as much notice as possible (except for emergency or urgent works)
  • keeping the durations of the restriction to a minimum

The minimum standard notice period for any TTRO for planned works is 12 weeks, emergency or urgent works aside. A shorter notice period (early start) may be agreeable with Dorset Highways for planned activities, subject to:

  • the duration of the restriction
  • the road space being available
  • the amount of administration required to fulfill the application
