Jan De Nul renovates Leonard tunnel

During the night of Tuesday 18 April, Flemish Minister of Mobility and Public Works, Lydia Peeters kicked off the second phase of works in the Leonard Tunnel in Tervuren. The minister took a seat in Jan De Nul's tire crane and symbolically placed the first demolished material in the waste container. Jan De Nul is responsible for renovating the tunnel under the Leonard intersection to extend its lifespan.

The Leonard Tunnel, under the intersection of the E411 and R0 in Tervuren, has four tubes, one for each direction of travel on each highway. Since its construction in the 1960s and 1970s, the tunnel's concrete has suffered from seeping water, de-icing salts, and exhaust fumes.

The tunnel will remain open during the day

Work on the R0 tunnel will last until spring 2024. After that, works on the tunnel of the E411 will commence. The works should be completed by the beginning of 2025. To limit traffic disruption, Jan De Nul is working on the tunnels at night, closing them completely and diverting traffic. The tunnels will remain open during the day, with a minimum of two lanes available in each direction on weekdays.
