Two super-span gantries were successfully installed over the M25 on Saturday night (25 Jan), marking another milestone on the scheme.
The gantries measuring an impressive 44 and 54 metres in lenght, were constructed off-site, stretching over eight lanes of the M25 carriageway and its two slip roads at junction 28.
When operational, the gantries will house signs which have the latest technology to keep road users informed and up to date.
Zachary Pepper, National Highways Project Manager, said: “This complex operation saw the completion of a series of improvements, allowing road users to safely navigate through this busy junction in the near future. We would like to thank the construction team and the support from the local community in reaching this significant milestone.”
Hugh McNally GRAHAM Project Manager said: “Both super-span gantries were installed overnight during a full closure of the M25 in both directions and lifted into position by two 450 tonne mobile cranes, with the carriageway reopened in less than 9-hours, keeping disruption to a minimum for road users.
“The safe and successful delivery was a result of precise planning by both the Project Team and Supply Chain, well done to all involved”.
