News and Updates

Galway City – Middle Street Traffic Management

As part of this project, essential works are required to replace a section of a collapsed sewer along Middle Street in Galway City which is causing the sewer to block up.
To facilitate these works, Middle Street will be closed from 7am on Monday 17th June until 7pm on Thursday 20th June.

Local access will be maintained on the first half of Middle Street up to St. Augustine’s Parish Church for residents and deliveries. The direction of traffic will be reversed on St. Augustine Street and a diversion route will be signposted.

The remaining sewers along Middle Street will also be rehabilitated using trenchless no-dig technology.

We apologise for any inconvenience that may be caused due to these necessary repair works. The Project Team will notify all residents and businesses via letter drop in advance of works commencing to provide contact details.

Traffic Management

  • To facilitate the construction of new sewer manholes, the works will require the closure of Cross Street from the junctions with Middle Street and Mainguard Street
  • The road closure period will extends for seven weeks from Monday 7 January 2019 to 22 February 2019. All traffic will be diverted via Father Griffin Road, Fairhill Road Upper, Dominick Street & Bridge Street
  • We apologise for any inconvenience that may be caused due to these necessary rehabilitation works

Mitigation Measures

  • No works will be carried out during the month of December in order avoid traffic congestion during the Christmas period
  • No works will be carried out on William Street/Shop Street/High Street during July and August in order to avoid disruption during the peak tourist season
  • Irish Water and GMC will make every effort to ensure odours are kept to a minimum
  • Trenchless techniques will be used for liner installation, for this project in order to reduce the potential impact to businesses and residents during these works
  • For further information regarding the works please contact the Project Team on 1890 252 261 during office hours (8am-5pm)
