N/A Deliveries only

Irish Water is working proactively with our delivery partners and as part of a multi-agency working group to ensure that our construction works are carried out in a controlled and safe manner, in keeping with Government and HSE guidelines to protect workers, their families and the broader community.

VMS Signage has been erected advising of works. Advanced traffic management warnings will be provided using signage and AA Road Watch. These works will be carried out in phases to reduce impact to businesses and residents. Local access will be maintained at all times. Working areas will be kept to a minimum to minimise any traffic congestion. Residents in Carrickbrack Road have been notified of the works.
