Apply for a temporary TRO

How and when to apply for a temporary TRO (TTRO).

1 Overview

A temporary TRO (TTRO) is needed to:

  • temporarily close roads
  • introduce waiting restrictions
  • introduce speed limits to maintain safety during works near the highway or to hold special events.

Without an appropriate TTRO the works or events taking place may be unlawful. If you are unsure whether or not you need a TTRO for works or events you are planning please contact us.

If you want to apply for a permanent restriction, please see Apply for a permanent TRO.

2 Special events

Smaller events, such as parades or markets, are normally administered by the district council for the affected area. Larger events, such as charity runs, cycle rides or concerts which involve temporary traffic management lasting all day or over a weekend, require a TTRO made by the County Council.

We operate a framework for managing planned events on the highway, which can be made available by contacting us.

3 Timescales

Orders can be made to cover works for up to 18 months (for works on roads) and up to 6 months (for works on public footpaths or bridleways). These periods can sometimes be extended if necessary.

A minimum of 8 weeks notice is needed to process an application for a TTRO. Events under section 16a may require up to a minimum of 12 months notice. For more complicated works on the highway, a longer notice period may be needed to organise them properly.

The County Council reserves the right to request changes to the dates of works to avoid conflict on the road network.

4 Costs, payment and cancellation


All costs for the TTRO are the responsibility of the applicant.

  • For emergency situations of less than 21 days duration or planned works of 5 days or less (S.14(2) Notices) a charge of £557.00 is payable.
  • For planned works of 6 days or more (S.14(1) Orders) a charge of £2,789.00 is payable.
  • For special events on the highway (S.16A & B Orders) a charge of £2,789.00 is payable.

The cost of temporary traffic management and diversion signing are not included in these costs.


You will need to provide a purchase order number when applying. 


In the event of cancellation of a TTRO request within two weeks of a start date, the full costs will be charged.

In the event of cancellation with more than two weeks notice, a reasonable charge for any costs incurred by the County Council may be charged, and you will be advised of the appropriate amount.
