Leopold II tunnel

Leopold II tunnel, Belgium

Renovation works to the Leopold II-tunnel in Brussels started in 2018. Consortium CIRCUL 2020 with Jan De Nul Group, Besix and Engie-Fabricom took on the task. The works will take 3 years to complete. In addition, the Consortium will take care of tunnel maintenance for a 25-year period. This guarantees the quality of the renovation works. The works will mainly be carried out at night and during the summer holidays. This will ensure that the tunnel remains accessible as much as possible.

The Leopold II tunnel was built in 1986, connecting the Flemish motorway network with the centre of Brussels. Its 2.5-kilometre length makes it the longest and most complex of the Brussels road tunnels. Inspections revealed that the tunnel required thorough renovation. Waterproofing, road deck and electro mechanical installations needed replacing. Asbestos embedded in certain joints and present in paint also had to be removed. In addition, the consortium will renovate all emergency exits and build 17 new ones, in line with European safety regulations. Finally, the tunnel will also be put in a new jacket: both lighting and scenography will be thoroughly modernised.
