National Highways’ Road Investment Strategy for England’s strategic roads has committed to upgrading many the remaining single carriageway sections of the A303.
The D1 section between Lietavská Lúčka and Dubná Skala in Slovakia includes the partially completed 7.5km twin-tube Višňové Tunnel - to be the country's longest.
The contract, in Slovakia, also includes IT equipment for the D1 motorway stretch Lietavska Lucka - Visnove - Dubna Skala of which the tunnel is a part.
The new sections of the Pedemontana Lombarda motorway near Milan in northern Italy will deploy smart technology to help with maintenance of the infrastructure and traffic control.
