M42 timelapse bridge demolition

Contractors working for HS2 have removed a 4,000 tonne bridge over the M42 to make way for the construction of the new high speed line across the motorway near the Interchange Station construction site in Solihull. A team of 20 demolition experts from Solihull-based firm Armac, working on behalf of HS2’s main works contractor in the Midlands, Balfour Beatty VINCI (BBV), carried out the demolition in just 16 hours. The operation was coordinated in conjunction with National Highways, who were able to open the motorway section between Junctions 6 and 7 on Sunday at midnight, which was 5 hours earlier than planned, reducing disruption to road users. Starting at 07.00 on Saturday 10 February, the demolition team used a 100 tonne excavator and a further seven 50 tonne demolition excavators to complete the operation, supplemented by numerous breaker and cruncher attachments. Six articulated dumper trucks transported the excavated material to a local stockpile where it will be crushed and reused on HS2’s haul roads and work sites. Once the bridge was demolished at around 15.00 on Saturday , the debris was removed, the matting taken away, carriageway cleaned, and central reservation and verge restraint systems reinstated, ready for the motorway to be re-opened at midnight on Sunday 11 February. It is the second of two 4,000 tonne bridges in close proximity over the M42 which needed to be demolished so HS2 can build a new twin box structure, which will carry the high speed line over the motorway in the future. The operation by Armac to demolish the first bridge in August last year was delivered 14 hours ahead of schedule.
