In a significant development for the UK’s road network, GRAHAM, a Northern Ireland-based construction and civil engineering firm, in partnership with National Highways, has reached two important milestones in the M25 junction 28 improvement scheme.
One of the project’s major steps was the positioning of six 70-meter beams that form part of the new Grove Bridge. These beams are key components in the construction of the Grove Bridge Road deck and the new loop road beneath Maylands Bridge, as well as the new A12 eastbound off-slip, which is currently being built.
To address the challenge posed by overhead power cables in the area, the project team used modular transporters, which enabled safe and efficient installation of the beams.
Additionally, the project saw the successful installation of eight large pre-cast concrete sections for the new Weald Brook culvert.
This operation was essential for the widening of the M25 entry slip road and was completed ahead of the planned schedule. The early completion facilitated the sooner reopening of the M25, reducing the impact on road users.
These improvements at junction 28 are expected to enhance traffic flow and contribute to a safer and more connected road network.
