Oldbury Viaduct Repairs approaching South-bound Completion

CRL's repair teams are steadily completing areas of repair on the southbound deck. The whole of Zone 5 and part of Zone 4 (approx 1km) have been completed and handed over to the deck waterproofing teams. Surface preparation, verge waterproofing and kerb laying is underway.

CRL still has two hydro-demolition crews, three welding crews and four trim and repair teams working double shifts, to complete recently released repairs. These are progressing well. Joinery teams are working under the deck preparing areas beneath the northbound carriageway, A CRL team is also underneath doing soffit and edge beam repairs.

The BMV Oldbury team are pushing forward with waterproofing, kerb laying and lighting duct laying and re-surfacing should commence later in May.

At more than £100 million, M5 Oldbury is the largest concrete repair project, by value, ever carried out in Britain. The works, taking place along a two mile section on the viaduct’s southbound carriageway, between junctions 1 and 2, involves almost 500 people on the project, who are tasked with carrying out the following:

• Erecting almost 400 km of scaffolding (with enough scaffold boards to cover seven football pitches and enough staircases and loading bays to get to the top of Ben Nevis and Snowdon) 
• Removing and reconstructing more than 10,000 cubic metres of concrete joints
• Removing and replacing an estimated 4,000 tonnes of concrete
• Removing and replacing 30,000 tonnes of road surface
• Removing and replacing more than 100,000 square metres of existing waterproofing
• Removing and replacing 200 tonnes of steel that reinforces the structure
• Removing and replacing 250 lighting columns
• Replacing 5km of drainage, to prevent flooding
• Removing and replacing 10km of cabling
