One of Helston's roads has been closed for the second time this year – and will remain shut until 2022.

The closure relates to Penhellaz Hill, but also affects Cross Street, preventing access to through traffic for more than three months.

Both roads were already closed for a number of months earlier this year, while repairs were carried out in Penhellaz Hill.

However, just a few months after reopening the closure is back in place and is now expected to last until January 28 next year.

It relates to the Lanjowan retaining wall, with the latest work involving mesh and bolt strengthening to the existing highway retaining wall, rebuilding and repairing the parapet.

Pedestrian and vehicle access to residents and businesses will be maintained throughout.

The traffic order will be in force 24 hours a day, including weekends, although access will still be given to emergency services and any vehicle needed in an emergency, such as a loss of utility supplies.

Cornwall Council has said that an alternative route will be signposted at the site.

The road and the rock slope below are considered to be public highway and as a result is the responsibility of Cornwall Council.

Back in July Cormac issued a report on the road, as part of a planning application for proposed engineering works to stabilise the site and build a 1,200mm high wall.

However, last Thursday Cornwall Council confirmed that the application had been withdrawn.

A spokesperson for Cormac told the Packet this week: “We are currently in the second phase of works to stabilise a slope at Lanjowan, Helston.

"For safety reasons it was originally planned that the wall would need to be removed, then rebuilt on completion of the project.

"However, in an effort to preserve this important local structure, we have reviewed our intended method of works and it is now able to remain in place. We therefore withdrew the planning application.”

In the now withdrawn application, it was stated that following reports of concerns from the landowners and the highways maintenance team, Cornwall Council had commissioned the Engineering Services Laboratory of Cormac Solutions Limited to undertake an assessment of the rock slope.

It found that there were various unstable overhangs and "wedge failures" that had "undermined the highway parapet, unstable large rock blocks and potential failure zones."

It went on to say that the parapet wall immediately above the car park was affected by ongoing cracking and deterioration at two separate locations.

Cormac said in the report: "Parapet failure is associated with undermining of the highway from progressive deterioration and discontinuity-controlled failure of the rock slope.

"This area of structural instability presents a risk to both site operatives during the remedial works (falling debris) in addition to road users (unsupported carriageway edge) and will require work to be conducted under road closure."
