Hill will be seconded from consultant CH2M and will take up his new position next month to replace Simon Kirby who quit in September to join Rolls Royce.
HS2 Ltd Chairman David Higgins said: “I’m pleased to welcome Roy Hill back to the team.”
“His understanding of the project and the industry puts him in an excellent position to continue the significant progress made under Simon Kirby while we continue our search for a permanent CEO.”
“Roy’s secondment from CH2M will allow HS2 to benefit from his broad experience overseeing some of the world’s most complex infrastructure projects.”
“He is uniquely qualified to fill this interim role, seeing HS2 through its upcoming milestones and into the start of construction next year.”
