Belgium’s Wallonia Province will revamp 55 road tunnels. The work is expected to cost €90 million.
The upgrade work should be complete by 2030. Around 50% of the work will be for seven of the biggest and most important tunnel sections. These are located in Liège and in the centre of Charleroi.
The tender process for the tunnel works has yet to be announced.
The work is needed to bring the tunnel sections into line with the latest European safety requirements. The improvements will also help with capacity, as well as ensuring the structure of each of the tunnel stretches remains stabilised.
