Almost 24,000 cars can go by in an hour in both directions. It took general contractor Besix  only a remarkable eight months to complete the deck construction. Overall, the bridge is 300 metres long, 22 metres wide and 15.5 metres high. The striking characteristic steel arch is 42 metres high and comprises 40 steel segments.

Mammoet teamed up with Aertssen Machinery Services to install key elements of the bridge. Forty steel segments of the infinity arch, weighing up to 130t, needed to be installed over the creek and above the bridge deck, which could not support a suitably sized crane.

The team used two lattice boom crawler cranes to install the segments. Mid-bridge segments required tandem lifts by the two cranes positioned on opposite banks of the creek and with a working radius of 140m.
