Engineering dreams come true

Seymour Whyte delivers its first cable stayed bridge – a dream come true for founder John Seymour.

A bespoke segmental cantilever erection methodology was developed to install the sub-50m shared user single pylon asymmetric cable stayed bridge, at Narellan Road over the Hume Highway in Campbelltown, south west Sydney. The bridge has a steel ladder type deck and a reinforced concrete topping slab; and is supported on two permanent concrete piers with a fanned arrangement of cables.
