Eurovia, a subsidiary of French concessions and construction company Vinci, has won two design-build contracts to develop two major corridors in North Carolina, US.
The two projects, which have a combined value of €415m ($480m), are scheduled for delivery in 2022.
Work under the first contract will involve the addition of an express toll lane on the I-485 in Charlotte in each direction between the I-77 and I-74 (about 26km) and an additional free HOV (high-occupancy vehicle) lane.
These lanes are expected to improve traffic conditions along a corridor that is used by 146,000 vehicles a day.
The project will include 765,000m³ of earthworks, construction of 13 bridges and the laying of 700,000 tonnes of asphalt.
Under the second contract, in Winston-Salem (in Forsyth County), the work will involve the construction of an interchange over about 4km on the northern ring-road, near Route 52, which will be widened to six lanes.
The project will be optimised to consume less space and reduce the earthworks by more than 1 million m³. It will include 1.5 million m³ of earthworks, construction of 13 bridges and the laying of 100,000 tonnes of asphalt.
Earlier in October 2018, Eurovia, in collaboration with VINCI Autoroutes, built the world’s first ‘fully recycled road’ in France.
The road has been built as part of a major motorway renovation project on the VINCI Autoroutes network, along a 1km section of the A10 motorway between Pons and Saint Aubin in south west France.
Eurovia has completed this pilot experiment after more than two years of research and development.
In partnership with Marini-Ermont (Fayat group), the road has been made possible through the design of a mobile continuous asphalt plant (TRX100%), which makes it possible to recycle up to 100% of asphalt aggregates nearby road maintenance sites.
Most of the material required can be sourced from milling materials produced by the site.
