West Gate Tunnel: The Daily Commute as an Immersive Experience

Built through the collaboration of Transurban and the West Gate Tunnel Project team and designed by Wood Marsh, the West Gate Tunnel is one of Melbourne’s most ambitious infrastructure projects. By combining engineering, sculptural design, and cultural narratives, the project has transformed the everyday commute into an immersive experience.

Infrastructure as an urban narrative

The West Gate Tunnel is more than a new roadway; its primary goal is to relieve congestion and provide a direct connection to Melbourne’s western industrial port precinct. Crossing four waterways, the project’s design narrative reaches back 60,000 years, drawing on the history of Indigenous communities who fished and harvested eels among the thick reed beds. This imagery is intertwined with references to postcolonial settlement and maritime life, specifically the ropes used to hoist cargo from ships. The resulting master plan is conceived as a large sculptural net, where eels and colorful fish appear to move toward the tunnel itself, which acts as the net.

Two iconic timber structures mark the tunnel entrances – both sculptural representations of rope and basket weaving that also serve as geographic markers. Lighting plays a key role in the design: At night, it illuminates the tunnel’s entrance and exit with a diffused effect that aids wayfinding. By day, the shadows cast onto the road surface help drivers’ eyes adapt to changing light conditions.

Sculpturally integrated, the 50 m vent stack contrasts with the light, netlike structures, accentuating their more solid, fluid forms. Its metal-clad surface catches the light to create a sense of movement. Side ramps over the Maribyrnong River continue the formal narrative, representing a fish and two eels – one in dark tones and the other with striking colors. Finished in light silver-gray and with an array of brightly colored Perspex panels, the colored ramp produces a prism effect that reflects the patterns and shades of fish scales.

West Gate Tunnel: A public and symbolic space

Over nine hectares of public open space follow the route, integrating landscaping, art, and mobility. Modeled on European veloways and named for Australian cyclist Iris Dixon, the Dixon Veloway provides a 1.5 km cycling route between Footscray and the city. A vibrant green, the veloway contrasts with the surrounding infrastructure and acts as an intuitive wayfinding device.

The landscaping, developed in collaboration with Tract Consultants, features works by indigenous artists, children’s play areas, and a BMX pump track, expanding the project’s social impact. Elements often treated as purely technical – such as noise walls – have been rethought with fluid forms and patterns cast in concrete, while perforated metal structures form pedestrian pathways that are lit internally at night.

Rows of illuminated orange poles mark the project’s beginning and end, serving as both sculptural and wayfinding elements. Echoing the yellows and reds of existing road infrastructure, the design blends these shades into a unified color language that ensures clarity and visibility.

More than just an improvement to Melbourne’s road network, the West Gate Tunnel project is a narrative device connecting past, present, and future.
