Costain Group PLC has achieved a new milestone in the A30 dualling scheme in Cornwall. The company successfully dismantled an old 164-foot structure as part of the project. The high reach demolition process involved excavators carefully removing spans, parapets, and steelwork. The work was completed within a day and a half, with debris being removed and banking replaced before the road could be reopened. The Scorrier to Boxheater section of the A30 was closed for the duration of the demolition and reopened to traffic on Monday morning.
