Moller Architects | Design and Technical Delivery Team

An architectural gateway shaped by structure and landscape.

While working at Moller Architects, I assisted Gordon Moller with the design development of the Ormiston Road Bridge, working closely with Beca and acting as an interface between the architectural and engineering teams. It was an opportunity to be involved in a project where architecture and structural engineering were closely interdependent, each informing the resolution and expression of the other.

Designed by Craig Craig Moller Architects in collaboration with Beca, the bridge was conceived as more than a means of crossing the developing Flat Bush landscape. It was an opportunity to create a distinctive gateway into a new community, bringing together engineering, architecture and the surrounding public landscape.

Completed in 2008, the bridge is New Zealand's first modern major cable-stayed road bridge. Its design explores a sense of lightness, using two slender, inclined concrete pylons and an arrangement of steel cables to support the bridge deck. Rather than presenting as a heavy piece of infrastructure, the structure has a deliberate sense of movement, with its angled supports giving the bridge a distinctive architectural presence.

One of the more thoughtful aspects of the design is the separation between the carriageways, creating a generous opening that allows daylight to filter through to the landscape below. Pedestrian and cycle connections further integrate the bridge with its surroundings, allowing the park and public spaces to remain connected beneath the crossing.

The structural elements are expressed as part of the architecture, from the inclined concrete pylons and cable arrangements to the distinctive illuminated lattice structures at their summits. By day, the bridge establishes a strong visual marker within the developing township; by night, its illuminated forms create a recognisable landmark.

What I find particularly interesting about the project is the relationship between the apparent complexity of the engineering and the clarity of the architectural idea. The bridge is a piece of essential infrastructure, yet it also contributes to the identity of the place, demonstrating how a necessary connection can become a meaningful part of the wider landscape.
