The proposed Circuit of Wales - aiming to host international motorsport events such as MotoGP, World Superbikes, World Motocross and World Touring Cars - has reached an agreement with FCC Construcción.
FCC Construcción has previously been involved in creating the F1 Track at Valencia and Circuit of Jerez in Spain. FCC will form a partnership with local construction firm Alun Griffiths (Contractors) Ltd of Abergavenny.
A planning application for the £250m Circuit of Wales project, near Ebbw Vale, will be delivered in November.
“The people of Wales, and Blaenau Gwent in particular, should be really excited about what will be built,” said Michael Carrick, chief executive of the Heads of the Valleys Development Company.
“Having seen the work that our construction partners have done in the past, I've no doubt that the Circuit of Wales will be a diamond in the British sporting landscape.”
