SkyPath will use leading marine technology composite material which is light and very strong, in the form of a series of U-beams that clip on to the underside of the eastern edge of the bridge with a composite foam core deck.
Horizontal composite rods are spaced out across the enclosure to allow viewing and for maintaining safety. Composites are slightly more expensive than a comparable steel structure, but make up for this in terms of buildability, long-term service life, lower maintenance costs and weight saving.
Being 4m wide, SkyPath has sufficient shared space for walkers, joggers and cyclists, with additional two-metre extensions for five observation decks at the structural piers. SkyPath will be constructed in modules that have been prefabricated off-site. They will be placed on the side of the bridge at night to minimise traffic disruption.
