Balfour Beatty commences M3 bridge improvement following successful demolition works

22 November 2016


This weekend, Balfour Beatty, the international infrastructure group, demolished the Woodlands Lane Bridge which stretches the M3 motorway between junctions 2 and 3, in Windlesham, Surrey,marking the first phase of works to replace the integral bridge. An option to strengthen the existing bridge was considered before the decision was taken to demolish and rebuild it.

The demolition of the concrete bridge forms part of a wider £174 million improvement scheme which Balfour Beatty is delivering on behalf of Highways England to reduce congestion on this vital route between London, the south coast and the Solent ports.

The controlled demolition was carried out using a variety of methods to break up the structure and protect the carriageway beneath, including the installation of plywood protection, 150mm of timber mats and a further 600mm of crushed concrete. Unfolding geotextile curtains were used to contain the dust and rubble when the bridge fell on to the protected area of the road.

Over 250 engineers, construction and support workers delivered the project which was carried out in the early hours of Saturday morning to minimise the impact on road users. The work was completed on time and the carriageway reopened ahead of schedule.

This section of the M3 is used to make more than 130,000 journeys every day. Once work to convert it into a smart motorway is complete road users will benefit from an extra lane in both directions, increasing capacity by a third and the use of technology to vary speed limits and make the road more resilient to disruption.

Stephen Tarr, Managing Director for Balfour Beatty said, "I am delighted that the work went according to plan in spite of the poor weather conditions, safely, on time and the carriageway was reopened ahead of schedule.

"The bridge demolition and its subsequent replacement will help ensure that people, communities and businesses remain connected as part of the strategically important upgrading of the M3 motorway between junctions 2 and 4A that is nearing completion".

Balfour Beatty is due to complete work on the M3 in summer 2017.
