A square cross-section rotates through 90 degrees from one end to the other, creating a fusilli-like twisted form. The two end portals are not directly opposite each other, and as can be seen from below, the bridge's geometry provides a rational way of dealing with the requirements of a skewed crossing.

Structurally, the primary element is an aluminium box girder, which helps reduce the weight and hence the loads on the supporting buildings. The girder twists in such a way that it is shallowest at its ends (rectangular in cross-section), and deepest at midspan (triangular), as befits the bending moment diagram.

The girder supports a series of square frames, with glazing between them, each of which is rotated approximately 4 degrees relative to its neighbour.
