New milestone reached in A30 dualling scheme in Cornwall
21 September 2023
Costain, the sustainable infrastructure solutions company has reached another milestone in their work on the A30 Chiverton to Carland Cross dualling scheme in Cornwall. Video footage shows the 32-year-old Tolgroggan bridge between Scorrier and Boxheater near Redruth, being dismantled and removed during a full weekend closure of the road.
Costain dismantled the old 164-foot structure started at 9am on Saturday 16 September and the high reach demolition process saw excavators meticulously and safely pick away the spans, parapets and steelwork. The work was completed by midday on Sunday 17 September; debris was removed and banking replaced, before the road could be reopened.
The Scorrier to Boxheater section of the A30 was closed from 8pm on Friday 15 September, and the road reopened to traffic just before 2am on Monday morning.
Alongside the Tolgroggan bridge demolition, a realignment of the A30 also took place at the Chiverton interchange as work progresses on the new interchange flyover, and preparatory work continued at Marazanvose ahead of a forthcoming realignment to allow for work to continue on the scheme’s ‘green bridge’.
Ann-Marie Morrison, National Highways Client Director said: “This is another important milestone for the A30 dualling scheme in Cornwall. The video demonstrates the meticulous work our team undertook to dismantle the bridge safely; and it’s a testament to their skill that it was completed so swiftly.”
Neil Winter, Senior Project Manager for National Highways’ A30 Chiverton to Carland Cross scheme, said: “We appreciate road closures have an impact on people’s journey times, we understand roadworks can be frustrating, and we thank people for their patience during this weekend’s closure. The A30 closure enabled our contractors Costain and their teams to make real progress with a number of works at the weekend, we’re keeping all closures to a minimum and we’ll ensure we communicate well in advance any further closures later in the year.”
The new carriageway is scheduled to be opened at the end of Winter 2023/2024.
