This page includes information on current and future road closures, applying to undertake works/hold events on the public highway and how these works are coordinated.

Current and upcoming road closure projects can be viewed at:

Road works are an inevitable consequence of the need to improve roads or to maintain the services that are needed by households and businesses. Roads may also be closed or obstructed to allow roadside works to be undertaken, such as tree felling, wall repairs or deliveries to and from premises.

  • Road Works Coordination

    • The States will co-ordinate these in such a way as to minimise disruption to road users, and at the same time give the public as much information as possible.
    • As well as sending out regular updates to the media, road works are publicised on a website called IRIS (Island Road works Information Service).   This can be viewed at
    • Process
    • As soon as an application for a road works project is received it is entered onto the IRIS system (or in the case of the utilities and road maintenance they are entered directly on to the system).   However, the application will only be displayed once the application has been considered against the Roadwork Policies (available to download) and initial approval had been granted.
    • Nearer to the time of the closure, further information may be added on the IRIS map, such as one-ways or diversion routes required to manage traffic.
  • Safety at Street Works and Road Works

    • The 'Safety at Street Works and Road Works' Code of Practice, which is based on the UK Department of Transport "Red Book", provides guidance and information in respect of works taking place on or adjacent to the public highway in the island.
    • A copy is available for download here:  pdf icon Safety at Street Works and Road Works [3Mb]
  • Road Work Updates

    • Currently, Traffic and Highway Services distribute regular Alerts and Updates to media organisations, commercial road users and emergency service providers, which provide up-to-date information on road closures and traffic management arrangements. This information is also posted to our Twitter feed @GsyTraffic and on our Facebook page.
