The 620m long composite viaduct, which forms the northern end of the A38(M) Aston Expressway near ‘Spaghetti Junction’, has started to show signs of deterioration having been built in the early 1970s.
Works will start this month to strengthen the viaduct’s superstructure with steel plates secured in position using a combination of welding and bolting.
Anti-corrosion paint will also be applied to the structure, alongside other refurbishment works to help preserve the viaduct’s longevity and minimise the need for future work.
Deon Scholtz, operations director for VolkerFitzpatrick’s Infrastructure division said: “This is a vital part of Birmingham’s road network, and we look forward to working with the council to provide an integrated solution that achieves high levels of technical capability and service, leading to a safe, successful project completion.”
Cllr Liz Clements, Cabinet Member for Transport at Birmingham City Council commented: “This is a significant investment into a key piece of our city’s highways infrastructure. If we are to ensure people can move around the city as easy as possible and help business flourish, it is vital we carry out projects like this.”
The viaduct will remain open during the works, in order to minimise disruption.
To enable this, VolkerFitzpatrick will be using high level access platforms spanning from pier to pier.
As the structure spans significant infrastructure, including live electrified rail lines, the River Tame, main roads and local businesses, VolkerFitzpatrick will be taking steps to maximise safety on site, to engage with the local community and to minimise any environmental impact from the works.
