South Wales Gas Pipeline

The South Wales Gas Pipeline is a gas transmission line running across Wales and England, linking liquefied natural gas terminals at Milford Haven to the national network at Tirley in Gloucestershire. The pipeline travels through diverse terrain and supplies a significant portion of the country's gas needs.

The pipeline was built between 2004 and 2007, marking a turning point for Britain as it shifted from energy exporter to importer due to declining North Sea oil reserves. The project reflected the country's changing energy needs.

The pipeline construction led to archaeological discoveries, including sections of an ancient Roman road and Bronze Age cremation locations in the Welsh countryside.

The pipeline runs underground over long distances through various regions, so it is not directly accessible or open to public visits. If you want to learn more about this infrastructure, you can explore online resources or contact local visitor information centers.

During construction, the project uncovered archaeological treasures including traces of an ancient Roman road and Bronze Age burial sites scattered across the Welsh landscape. These discoveries provided insights into the region's deep past.
