Costain has been appointed to upgrade the M1 J28 to 31 and J32 to 35a in deals worth around £125m.
The M1 J23 to 31 deal is the final of four schemes that were set out for ‘speedy’ construction by the government in October 2012.
The two schemes are adjacent to each other and Costain said that by undertaking both projects it would be able to “effectively manage road space between them and reduce disruption to road users”.
Work will start immediately and complete in early 2017.
When the Department for Transport first set out the timetable for the M1 J28 to 31, it said the work would complete by spring 2015.
This project will add extra capacity on the M1 near Sheffield along 18.9 miles between J28 and J31, the primary strategic link between Nottingham and Sheffield.
Construction News reported in July that Balfour Beatty had been chosen for a £129m M3 upgrade deal, a project first set out for ‘speedy’ construction by the government in November 2012, which would complete two years later than initially planned.
In July 2013, Costain was chosen under an ECI deal for the £34m A160/A180 upgrade scheme, a scheme that had been delayed for years before being earmarked for accelerated delivery.
The final scheme set out by the DfT for ‘speedy’ construction was the project to increase the capacity of the M6 between J10a and 13, awarded to Carillion in a £70.5m deal in October 2013.
Costain Infrastructure managing director Darren James said: “Costain provides innovative, technology-led solutions to address major national infrastructure needs, and we are delighted to have been awarded these further significant contracts by the Highways Agency, reinforcing our position as a long-term partner of choice.”
