Carillion is believed to have won the job with a bid of around £18m against a £30m-£40m initial cost estimate for the 3-mile Finningley and Rossington Regeneration Route Scheme (FARRRS).
Birse, Morgan Sindall and Graham Construction also bid the scheme, which received a spread of prices from £18m to £25m
The FARRRS scheme was one of several road projects to win Government cash backing for its ability to galvanise further development of Robin Hood Airport, the Strategic Rail Freight Interchange proposal adjacent to Junction 3 of the M18, as well as the reclamation of Rossington Colliery.
Much of the new highway will be built across low lying open farm land to the north of Rossington and will connect the M18 motorway with the the A638 Great North Road and B6463 Sheep Bridge Lane, known locally as Parrot’s Corner.
The risk of flooding means that most of the highway will be raised on an embankment, needing 700,000 cu m of fill material.
The first 1 mile from the motorway is designed as dual carriageway, with the remaining 2 miles from a new Rossington roundabout to Parrot’s Corner single carriageway.
The scheme also includes a 1km spur from the roundabout to the former Rossington Colliery.
Reclamation and redevelopment of the colliery site is due to start next year. This will include the recovery of coal from the colliery spoil tips and development of an eco-village.
Several structures will be needed on the route, including crossings over the Brancliffe to Kirk Sandall railway line and the East Coast Main Line and two subways to maintain public access for vehicles and pedestrians.
There will also be extensive ditch and flood relief culverts as well as attenuation ponds built to control discharges into the local watercourses.
