1146 Balfour Beatty is to work on a €163.5 million (£129 million) upgrade project for a 21.4km stretch of the M3 motorway in the UK. The work involves upgrading the route to smart motorway status and is being carried out for the UK Government’s 2309 Highways Agency. This project will increase capacity, reduce congestion and shorten journey times for the 120,000 motorists/day using the route. This section of the motorway runs through the counties of Hampshire and Surrey, between Junction 2 which is interchange with the M25 orbital motorway around London and Junction 4a (Fleet). The route will be upgraded to a four-lane motorway by converting the hard shoulder to a permanent running lane. Electronic signs, operated by a regional control centre, will be installed to manage the flow of traffic in response to driving conditions.

Mobilisation work is due to start at the beginning of August. Main construction work is due to start in the third quarter of 2014 with completion scheduled for spring 2017. Construction activity will include installing and refurbishing gantries, new static and variable signs, concrete safety barriers, drainage and surfacing works.

The contract is the latest in a series awarded to Balfour Beatty since the company was appointed to the Highways Agency's National Major Projects Framework in 2010.  In June 2014, Balfour Beatty was awarded the M60 J8 to M62 J20 smart motorway scheme.  In April 2014 the company’s construction joint venture with Skanska completed upgrading a stretch of the M25 to a smart motorway, and in January 2014 Balfour Beatty completed upgrading parts of the M4 and M5 to a smart motorway.

The M3 passes through Chobham Common, one of the largest areas of heathland in Surrey, and   Balfour Beatty’s sustainable design will take into account ecological considerations with natural habitats being reinstated.
