M4 team passes major bridges milestone

The M4 junction 3 to 12 upgrade team passed a major milestone with the successful demolition of Datchet Road bridge last weekend.

Datchet Road bridge was the last bridge to be demolished as part of the motorway upgrade being carried out by the Balfour Beatty VINCI joint venture on behalf of Highways England. All eleven bridges which crossed the M4 have now been demolished and beams installed for the new structures over twenty weekend closures from September 2019 to this December.

The bridge replacement works, required to accommodate the new fourth running lane on the motorway, have all been carried out during weekend closures on the M4 between junctions 4b and 8/9. In total, 22,000 tonnes of bridge have been demolished and 792 metres of new bridge installed.

The first bridge to be demolished in September 2019 was Recreation Ground bridge near Slough pictured above, which was just 400m from the final demolition, Datchet Road bridge at the weekend.

Steve Jagger, Balfour Beatty VINCI Project Director, said:

Reaching this major milestone is testament to the advanced engineering capabilities and expertise of all the teams involved.

We continue to collaborate with Highways England and our supply chain to successfully deliver this significant project, which will reduce congestion and increase capacity for road users on the M4.
