The new road connection Rotterdamsebaan connects the highways (A4 / A13) and the central ring of The Hague and makes the region more accessible. The traffic to and from the motorways can thus be distributed better and the congestion on the Utrechtsebaan is less.
The 4 kilometre long road connection has a 1800-meter-long tunnel and a 450-meter-long sunken roadway with several underpasses. The drilled tunnel consists of two tubes with an internal diameter of ten meters. Each tube has 2 lanes. The tunnel is drilled underneath a residential area, a park and a canal.
The tunnel is called the Victory Boogie Woogie Tunnel, named after the famous unfinished painting by the Dutch painter Piet Mondriaan.
The Rotterdamsebaan project is a prime example of sustainable infrastructure in the Netherlands. The tunnel has many sustainable applications such as solar panels, LEAB asphalt, sound converters and our Cradle to Cradle certified LED lighting. It is one of the largest tunnels in the Benelux and the longest tunnel that is equipped with BB Lightpipe lighting. The tunnel has a high architectural value, partly thanks to the lighting from BB Lightpipe.

Both the tunnel and the sunken location have a continuous BB Lightpipe light line on both sides at a height of 4,7 meters. The lightpipe lengths are custom made to the white curved wall elements, which ensures a sublime result. This appearance ensures a comfortable and safe passage for the road user.
The tunnel is equipped with 2.091 lightpipes, in lengths of 1,25 - 2,5 - 3,75 and 5 meters. The lengths are adjusted to the dimensions of the wall sections. A total of 1,461 external driver housings are installed, part of which controls 2 lightpipes. The light colour is set to 3500K, at the special request of the customer, which gives a warmer tone than the standard 5000K.
The lightpipes are placed at an angle of 35 ° for optimal light distribution. Advanced lighting via lens and foil techniques create a constant and even light distribution. This makes it is impossible to look directly into the LEDs from any position and thus eliminates glare effect which are often present when, for example, entering or leaving a car tunnel.
The specially designed suspension bracket connect the lightpipe to the wall construction. The bracket is developed by Cruxin within the TKH Group. Cruxin also acted as a system integrator for lighting and lighting controls.
Hight quality components
The hight quality components and good thermal distribution of the BB Lightpipe ensure a very long lifetime and low maintenance cost. An advanced lighting management extends the lifetime even more when keeping the LED's cool when dimmed.
LED drivers are placed externally as it is the most critical component. LED drivers are located in the service channel underneath the road surface. So when a replacement is needed it can be done easily and fast without without hindering traffic.
Bennie Elfrink of BB Lightpipe took care of the development of our innovative lighting solution. Paul de Graaf successfully completed the light calculations and project coordination between our factory, the system integrator and the installation company.
The customer now has high-quality lighting with a long life span and very low maintenance for a period of at least 15 years.
