Machines, men and materials on standby ready to begin work as soon as traffic controllers have closed the M1 motorway.Minimum time to demolish 1,400 tonne bridge over the M1

Recently the Costain-Carillion joint venture had to close a section of the M1 for almost 16 hours to enable time to demolish a bridge.

Machines, men and materials on standby ready to begin work as soon as traffic controllers have closed the M1 motorway.

The route between London and the Midlands was closed between Junctions 11 and 13 to allow the demolition of one of the motorway’s original bridges at Junction 12 as part of the overall programme of improvements at the interchange.

The jv team had between 8 pm on Saturday 30 June to noon on Sunday 1 July to remove the 41 metre, 1400 tonne reinforced concrete structure, which previously carried the A5120 that connected Dunstable and Flitwick.

A replacement – constructed from steel beams with an in situ concrete deck – was already in position and operational when the work got underway.    The job went smoothly, accomplished using hydraulic breakers, with the jv team able to hand the motorway back 30 minutes ahead of deadline.

Having worked through the night doing the demolition, final clear up and finishing works continued in the race against time.Unsurprisingly, the demolition attracted considerable attention. Regional press helped promote the message that the M1 would be closed and media were onsite to film the work and interview Highways Agency Project Manager, Lynne Stinson.

Having worked through the night doing the demolition, final clear up and finishing works continued in the race against time.

The team took the opportunity of the weekend closure to tackle extra work, meaning less disruption will be needed on other occasions.
