West Gate Tunnel Project

nearly complete

The West Gate Tunnel Project is a large-scale toll road infrastructure project in Melbourne, Australia, featuring almost nine kilometres of elevated carriageways and a complex junction of overpasses on the city's western edge. The project includes twin four-kilometre tunnels beneath Yarraville, new bridges over the Maribyrnong River, noise walls alongside the West Gate Freeway, and a cycling and pedestrian bridge with a connected veloway. The design incorporates artistic elements inspired by local history and environment, such as wooden 'fish nets', fish scale-like bridge panels, and orange poles referencing local landmarks. The project has faced delays, toxic soil discovery, legal disputes, and a $3.4 billion budget blowout but is nearing completion with an expected opening by the end of 2025.
