Contractors Balfour Beatty and Skanska have won a £321M design and build contract to upgrade two sections of the M25 around London for client the Highways Agency today.
The team is working as part of the Connect Plus consortium on a design build finance and operate (DBFO) contract. Connect Plus were awarded a £6.2bn DBFO contract to operate the M25 on behalf of the Highways Agency in 2009.
Work will begin in January 2013 for a scheduled completion in February 2015.
The team will upgrade 46km of the M25 between junctions 5 to 7 and 23 to 27 to managed motorway. This will add capacity by converting the hard shoulder to a traffic lane and using variable speed limits to control traffic. ConnectPlus says the “technology-driven” upgrades will to improve safety and reliability.
The work will also includes installation of emergency refuge areas for vehicles and road management technology as well as new concrete barriers in the central reservation.
