Leopold II tunnel, Belgium
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.
