Northern Gas Networks, which own the gas pipes across the region, invested £177,000 into pipeline improvements in the town. The work was carried out by United Utilities.
The scheme at Exchange Street, Market Place and Eastgate North, began in January and has been completed four weeks early. Roads will be open as normal this weekend.
Dean Shepherdson, United Utilities network operations manager, said: “Our engineers worked as safely and efficiently as possible to get the work completed on time and we are delighted the scheme progressed so well.”
In total nearly 300 metres of new pipe was laid to improve the gas network in the area for decades to come.
Mr Shepherdson added: “We want to thank businesses and residents for bearing with us while this essential work was completed.
“There is always going to be some inconvenience when we lay new pipes but Driffield residents and traders have been very understanding and its been great to work with them to make this scheme a success.”
Northern Gas Networks bought Yorkshire’s gas pipeline in June and appointed United Utilities, one of the UK’s biggest multi-utility companies, to carry out day-to-day operations.
