UPDATE: Friday 3.40pm. Drivers are warned that one lane on the westbound A30 near Redruth will remained closed over the weekend and delays are expected at rush hour this evening as work to investigate a hole that appeared beside the road continues.

The road was closed on Thursday afternoon after the hole appeared next to a section of the A30 between the A390 at Scorrier and the A3047 at Redruth. One lane was reopened later in the day.

Area Manager, Julian Strong said, “We have been working at the site since Thursday afternoon and have carried out an initial excavation to a 15 foot depth.

“This has shown hard rock around the area of the hole and under lane one of the carriageway. However safety is paramount and we will not open both lanes of the carriageway until we are absolutely sure it is safe to do so.”

Highways Agency contractors have been at the site around the clock since the hole appeared and  will continue to work as quickly as possible over the weekend to gain a clear understanding of the situation and rectify it as quickly as possible.

Delays are expected to be minimal over the weekend, but there may be delays later today (Friday) during the rush hour.

Highways Agency advice to drivers planning to use that section of the A30 is to check the latest conditions before they travel. 

UPDATE: One of the westbound lanes of the A30 is still closed between Scorrier and Redruth as geotechnical investigations continue into the large hole that opened up on the side of the road yesterday.

The road is expected to remain closed through into Saturday, with drivers advised to avoid the  road during peak traffic hours.

A Highways Agency spokesman said: "Geotechnical experts will work throughout the day to understand the nature of the hole and why it has appeared, and work toward a speedy repair.

"Delays are expected to be minimal this morning, but there may be delays later today should the lane closure still be in place during the afternoon peak. Highways Agency advice to drivers planning to use that section of the A30 is to check the latest conditions before they travel."

The A30 westbound was closed yesterday evening, due to the hole in the road between A3047 (Scorrier) and A3047 (Redruth) causing congestion to A3075 / A390 / B3277 (Chiverton Cross Roundabout).

A diversion via the A3047 was put in place.

The hole is approximately four feet across and up to 15 feet deep.

Highways Agency Area Manager, Julian Strong said, “At the moment we do not know what has caused the hole but we are working as quickly as we can to understand what has happened and identify a solution.
