Couvin motorway bypass (E420/N5)

The Couvin motorway bypass (E420/N5) is 13.8 km long and has a dual carriage way in each direction, a hard shoulder and 35 highway structures. Since October 2017, users have been able to drive on this 4 km section and thus avoid the centre of Couvin.

In mid-2019, the whole bypass will be open to traffic, with one single lane in each direction under the railway line in Frasnes. The works should be fully completed in mid-2020 with a dual carriageway under the railway line in Frasnes.

A four-phase project :

The construction of this motorway link, continued in France via the extension of the A304 linking the Belgian border and Charleville-Mézières (inaugurated in July 2018), meets several objectives :

  • Linking Northern Europe and the Mediterranean
  • Opening up economic opportunities for the south of Charleroi
  • Improving the flow of traffic between France and Wallonia
  • Improving road safety on the N5
  • Reducing congestion by heavy goods vehicles in the centre of Couvin

Within the framework of this project, many environmental measures were implemented to protect the fauna and flora :

  • Game crossings
  • Passages for bats
  • Dry benches for small fauna
  • Wildlife crossings for large fauna
  • Building toad tunnels
  • Restoring calcareous grasslands
  • Planting hedges, orchards and forest plants
Key figures €130,000,000 for the construction of this bypass, financed by SOFICO, with the help of a loan from the European Investment Bank which agreed to provide funding of €80,000,000for this project.
