slender and comfortable bridges
Our pedestrian bridges can generally be described as slender and comfortable. As footbridges are only carrying a relatively low load, it is quite easy to design a slender bridge deck. However, during the design process we always look for the optimum between main span, user comfort and structural height. As a result, not all bridges are of the same slenderness.
A well designed pedestrian bridge is easy to walk across for everyone. Slopes shouldn’t bee too steep and steps shouln’t be too high. We’ve written a lot about slope gradients, deck width and all sorts of footbridge specifications in the CROW Dutch design manual for bicycle and pedestrian bridges.

adding extra value
Sometimes a footbridge’s location simply offers opportunities too good to dismiss. A lovely natural waterway with green surroundings for instance might beg for a bridge to stand upon and wonder, rather than a bridge to simply cross the waterway. The Waalhaven bridge is an example of how easy it can be to add extra value to a functional bridge. By extending the bridge deck slightly past the stairway, we created a humble viewing platform that offers magnificent views across the port.
