If you are not sure whether you will require a temporary restriction to carry out works, please contact us at

Temporary Traffic Regulation Order (TTRO): You will need to apply for a TTRO for any planned works that will require a restriction. A TTRO may remain in force for up to 18 months.

Temporary Traffic Regulation Notice (TTRN): You will need to apply for a TTRN if a restriction is required immediately for urgent or emergency works such as repairs to a burst water main, gas leak or to restore loss of service to a customer.

Suffolk Police may also close roads for safety reasons.

Notice period

For any planned works that require a TTRO, we will require a minimum notice period of 3 months to process the application. However, Network Assurance may agree a shorter notice period in some circumstances.

For any works that require a TTRN, advanced notice to residents or businesses may not be possible due to the nature of the reactive urgent or emergency works.

Public Rights of Way

If you need to carry out works which may affect a Public Right of Way, you will need to contact Suffolk County Council’s Public Rights of Way Team, please visit Public rights of way and planning.
