A team from Jackson Civil Engineering featured in a battle against time in the final episode of a six-part TV series taking a behind-the-scenes look at the operation of the M25.
The show, Britain’s Busiest Motorway, revealed the usually hidden army of traffic controllers, patrol officers, engineers and maintenance workers who work around the clock to keep traffic moving on the London orbital motorway, which stretches 117 miles around the capital and is used for 73 million journeys a year.
The final episode featured Jackson’s project manager Ryan Smith and his team as they worked through the night with a 90-tonne crane as part of a scheme to replace an expansion joint on the New Haw Viaduct, between Junctions 10-11 of the M25.
The work involved a night-time closure of the motorway, from 10pm until 6am, representing a race against time to get the road open again in time for the morning rush hour.
Richard Neall, chief executive of Jackson Civil Engineering, said: “The M25 is used for four million journeys each day, and we have teams working around the clock on projects designed to keep traffic moving.
“We’re all too aware of people’s frustrations at being caught up in road works, but we hope this behind-the-scenes documentary will go some way to explain what we’re actually doing when we close a road.”
Jackson Civil Engineering has worked for M25 Operators Connect Plus and Connect Plus Services since 2009 on a range of different projects on the M25. The New Haw project is the third joint replacement scheme undertaken by the team.
Expansion joints allows structures such as the New Haw Viaduct to expand and contract with changes in temperature and load, but require replacement every 40 years or so. Thanks to an award-winning working method developed by Jackson, Connect Plus and Flint & Neill, the installation of temporary ramps on the road surface allows traffic to flow freely over the structure while work to remove the old joints is carried out from below. Whilst in situ on the New Haw Viaduct, 30.2 million vehicles have driven over the ramps, their drivers largely unaware of their presence, or indeed the work going on underneath them.
