Diversions and Safety Measures

  •  Covid-19 measures will be in place. 
  • A programme of repainting sections of the bridge will also be carried out.

Programme of traffic management restrictions

  • In order to carry out this work safely, traffic crossing the bridge along the A5 will need to be reduced into one lane from 7am to 3pm for the duration of the works.
  • On week days, between 7am - 3pm, traffic crossing the bridge will be managed by two way traffic signals.
