Steelwork creating improved A12 junction

Steel beams, measuring 48m in length have been installed to create the new Marylands Bridge, which forms part of the ongoing M25 Junction 28 upgrade.

The bridge will form the new A12 eastbound exit slip, and take traffic over the new Grove Bridge and loop road that are currently under construction.

Working on behalf of main contractor GRAHAM and National Highways, Severfield fabricated, supplied and erected the steelwork.

As well as connecting the A12 to the M25, Junction 28 also provides access to Brentwood via the A1023. It has been estimated that up to 7,500 vehicles pass through the junction’s roundabout at peak times.

The scheme’s improvements will increase capacity and allow the projected 30% traffic increase, expected by 2037, to pass through the junction.

The work is expected to be complete by mid-2025.
