This structure is a close resemblance of the viaduct crossing highway A4 between Vlaardingen and Schiedam, but with the bike path removed.
The tracks are on a 60 degree angle with the highway underneath.
The bridge originally was ~70m long, but was extended to ~100m when the nearby highway tunnel was doubled and the attaching roads needed more space. As a result the eastern end of the bridge looks slightly different then the rest of the bridge.
The current construction gives room for 4+2+4 lanes of traffic to pass under the viaduct, of which currently only the outer 2x4 are used.
In 2011 about 132.000 vehicles passed under the viaduct on an average workday.
The 2 'gaps' in the fences are there to leave room to put catenaries support beams.
