The West Gate Tunnel will improve travel to and from Melbourne's west and create a much-needed alternative to the West Gate Bridge. The project involves building four more lanes on the West Gate Freeway, twin tunnels under Yarraville and a new bridge over the Maribyrnong River that links to an elevated road above Footscray Road, taking people where they need to go in the city’s north. The project also includes 14km of new and upgraded walking and cycling paths for a continuous journey from Werribee to the city.
