Highways England has passed the halfway stage of major works at the famous Spaghetti Junction – having repaired and replaced damaged concrete at 158 locations on the huge structure.
Work is taking place around the clock on the £4.7m project to carry out vital concrete and waterproofing repairs to the 45-year-old structure, which carries more than 200,000 vehicles a day.
As part of the project, Highways England is using high-performance jet washers that break up parts of existing concrete – a technique known as hydrodemolition.
Workers operating the machinery have to wear protective suits (pictured) and to work inside a special cage designed to contain flying debris to a confined space.
The M6 will remain fully open during the work, although key link roads into Birmingham will remain closed until 4 September.
The Government-owned company said that last weekend saw the project reach the halfway mark with work progressing well despite severe weather. Teams are continuing to work 12 hour shifts in a bid to complete the programme as quickly as possible.
Project manager Jessica Kenny said that by utilising full weekend closures of the carriageway, the scheme will be delivered more quickly with work set to be completed in seven weeks rather than 30 weeks.
She said: ‘While we understand that nobody likes roadworks, the full weekend closures have allowed repair crews greater access to the carriageway compared to working in smaller sections when the road is kept open. This means we can work quicker and more safely to complete the scheme as quickly as possible.
‘And by doing this work in this way, it means that our crews have shortened the duration of the scheme considerably.’
Highways England said repair teams clocked up more than 4,400 hours of repair work last weekend alone.
