This bridge had to be able to accept the heaviest category of motorized traffic. Wood is hardly the most obvious material for constructing such bridges. All the same, the architects took the most simple bridge - a plank across a ditch - and 'covered bridges' as inspiration when exploring the possibilities of using wood as the principal material for the Akkerwinde bridge. It proved possible too, thanks to new wood bonding techniques. The bridge as built consists of two double-curved laminated trusses joined at the top by a hinge. Each truss is composed of a cross-woven network of curved timber struts that take up the tensile and compressive forces respectively. An identical second timber bridge over the A7 has been build at the Molenkrite.
