The Bevrijding Tunnel on the A12 motorway links Antwerp to Brussels. This 350m long tunnel which is composed of 2 tubes was built at the end of the 1970s. Approximately 40,000 cars pass through this tunnel every day.
The lighting system is almost 35 years old and needed to be replaced. The Flemish Ministry of Roads and Mobility (AWV) wanted a sustainable lighting solution that would reduce the energy consumption and guarantee safety and comfort for all motorists driving through the tunnel.
To achieve their objectives, they chose a lighting solution with the ContiLED. Installed in a continuous line, the ContiLED offers maximum visual comfort while providing the required lighting levels with significant energy savings. Indeed, thanks to this new lighting scheme, the Ministry will cut its energy consumption by 694,000kWh per year, which represents approximately €98,000. The long life of the LEDs will also lead to a reduction in maintenance costs.
A bright white light has replaced the old yellow light, improving visual comfort to safely guide drivers through this tunnel. The white light also optimises the visual perception of the drivers, highlighting any potential obstacles, to increase security in the tunnel.
BalPlast marker lights were installed along the entire length of the tunnel. Permanently illuminated, they clearly indicate the road and guide drivers naturally through the tunnel under normal circumstances and in case of fire.
A total of 542 ContiLED luminaires were installed in this tunnel, making it the first road tunnel in Flanders to be completely lit by LED lighting.
