Gas pipe replacement in Plymouth 'may finish early'

Mutley Plain closed
Mutley Plain was to be closed for six weeks

Gas pipe replacement work which has caused the closure of a main road in Plymouth could finish two weeks early, engineers have said.

The northbound carriageway of Mutley Plain has been closed to traffic as part of the 30-year pipe replacement programme across south-west England.

The work began last week and was expected to last six weeks.

Wales and West Utilities said an old water main could be used as a pipe channel, shortening the time required.

The utilities company said said it was looking if it was possible to use a "keyhole" technique to insert new plastic gas pipe into the existing water pipe.

Such a method of gas mains replacement, which would run along 230m (755ft) of Mutley Plain, would save time and reduce the amount of excavation required, it said.

It added that South West Water had confirmed to it that the water main was surplus to requirements.
