Development of the £315m Circuit of Wales project is set to start this year in the UK.
Planned as an international motorsport circuit, technology park and training facility, the Circuit of Wales will be developed across a 830 acres site of Blaenau Gwent.
Final planning hurdle for the development has been cleared in November 2015 by scheme promoter, the Heads of the Valleys Development.
Preparation groundwork at the site is expected to begin this month, which is likely to be followed by starting of the construction works in late February or early March.
While civil engineering firm Alun Griffiths is responsible for the preparatory works for the project, Spanish builder Fomento de Construcciones y Contratas (FCC) has been appointed as the main contractor, reports The Construction Enquirer.
According to the plans, the project will lead to the construction of a 3.5 miles long main race track, along with additional smaller circuits for karting, motocross and 4x4.
FCC will also be developing motor sports and automotive testing facilities under the project, including a driver training centre and automotive proving ground.
The plans also include development of a technology park and incubator at the site, along with a proposed 30MW solar park and two hotels.
The entire development is expected to be completed in 2020. However, the racing track is intended to host the British MotoGP in 2017, for which it needs to be completed beforehand.
