Balfour Beatty is working for the agency 8100 Highways England to reduce congestion this section of the M3 that handles more than 130,000 vehicle journeys every day. Once is it converted into a smart motorway and open in summer 2017, there will be an extra lane in both directions, increasing capacity by a third. Technology will be introduced to vary speed limits.

More than 250 engineers worked on the controlled demolition of Woodlands Lane Bridge which used a variety of methods to break up the structure and protect the carriageway beneath. This included installation of plywood protection, 150mm of timber mats and a further 600mm of crushed concrete.

Unfolding geotextile curtains contained dust and rubble as the bridge collapsed onto the protected area of the road below.

“The work went according to plan in spite of the poor weather conditions, safely, on time and the carriageway was reopened ahead of schedule,” said Stephen Tarr, managing director for major projects with Balfour Beatty.
