The gas works, which have caused so much upheaval since May, will finally be coming to an end this autumn.
The final phase is due to start on Monday 9 September and will see the closure of the High Street from the junction with Akeman Street/Frogmore Lane, to the roundabout at Christchurch Lane/Western Road. The closure will last for a further seven weeks.
The works are being carried out to replace the old metal pipes with modern plastic ones.
Bradley Barlow, spokesperson for gas distribution company SGN, said: ‘We’ve worked closely with the local authorities in planning this work and we will be doing everything we can to limit disruption during our essential project.
‘We appreciate that roadworks can be frustrating, however, the new plastic pipe has a minimum lifespan of 80 years. This means, once the work has been completed, Tring homes and businesses will enjoy the benefits of a continued safe and reliable gas supply for many years to come.’
