A robust and efficient arch bridge, a type often found at large spans over water in the Netherlands. The concrete military monument Plofsluis is flanked on either side by arch steel bridges. The new bridge has a much larger span than Overeindse bridge on the other side of the Plofsluis. In order to avoid domination by the new bridge we have designed it as a low arch with a powerful yet transparant truss structure. The top of the Plofsluis bridge has the same height as Overeindse bridge, resulting in a well balanced ensemble.
