The competition for a £110m Kettering bypass is hotting up, with seven major contractors reported to be interested in the scheme.
Funding of £110m was confirmed in the 2011 autumn statement for the scheme, which will see widening between junctions 7 and 9.
Construction intelligence business Glenigan has reported that Bam Nuttall, Balfour Beatty Regional Civil Engineering, Carillion, Costain, Morgan Sindall, Skanska and Sir Robert McAlpine are all eying the scheme.
Tenders are due to be returned in March for the scheme which will consist of widening works of approximately 4.6 kilometres of the A14 Kettering bypass between Junctions 7 and 9.
Main construction work is set to start on the scheme later this year.
The scheme proposes that the additional lane on each of the eastbound and westbound carriageways is provided by symmetrical widening of the existing rural two lane all-purpose dual carriageway to rural three lane all-purpose dual carriageway within existing land take.
