Wales & West Utilities has given details of forthcoming work to upgrade gas pipes in Acrefair and Trevor which will affect Llangollen people travelling through these areas.
The work is being undertaken as part of a multi-million-pound 30-year programe by the company to replace old metal pipes with plastic ones within 30 metres of buildings across Wales and the south west of England.
Work will start locally on September 9 on Llangollen Road and is expected to last until the end of November.
The company says it has worked closely with Wrexham Council to keep disruption to a minimum.
A two-way traffic light system will be in use throughout the works and this will temporarily change to three-way lights as work passes the junction of Station Road.
There will also be a two-week road closure in place on Tower Hill from both junctions off Llangollen Road.
Access to residents will be maintained via Tower Hill by the Towers Nursery and there will be a diversion route in place on the opposite junction towards the Pontcysyllte Aqueduct car park. This diversion will be via King Street and will be clearly signposted while the company is working.
