The bridge features two A-Frame masts, which support the bridge from the west bank.

The masts are positioned on a shared foundation and anchored at ground level by two 120mm diameter cables that are connected the tips of the masts. The forward mast is 80 metres and the back mast is 69 metres. Because of the angle at which the masts are positioned, the bridge stands at 70m above ground. The deck is 5 metres wide 4.1 metres above water at high tide. The bridge has a clear span of 145m.

The Electrical Services element of project comprised the installation of two feeder pillars and wiring to bridge and ground mounted lighting.

The installation was carried out on site to in-situ bridge sections and off site at the bridge fabricators workshop.

The naviagtional and feature lighting comprised:

• Balustrade mounted luminaires illuminating the bridge deck
• Underdeck mounted spotlights illuminating the bridge arms
• Ground mounted, bracketed floodlights illuminating the bridge masts with white light
• Ground mounted, bracketed floodlights illuminating the bridge masts with blue light
• Pole mounted, floodlights illuminating the bridge masts with white light
• Ground mounted, buried floodlights illuminating the mast feet
• LED luminaires fixed to the bridge arms
• Two navigation lights, one fixed on either side of the bridge centre
• Solar powered mast LED lights
