Hundreds of jobs set to be created by M1 contractor near Sheffield
Costain Serco - a joint venture of the two companies - is working on a two-year project to open the hard shoulder of the M1 as a fourth lane between junctions 28 and 31.
The consortium will bring opportunities at Markham Vale, near junction 29A, for apprentices, plant operators, foremen and civil engineers.
Work on the M1 is due to start next year despite safety concerns about loss of the hard shoulder.
Around 500 new jobs have been announced for Markham Vale during the last year.
