TheDomain Tunnel is a road tunnel located inMelbourne,Australia, which carries traffic westbound from theMonash Freeway to theWest Gate Freeway, running under theYarra River andKings Domain. The tunnel is part of theCityLink Tollway operated byTransurban and provides a bypass of the central business district.
The tunnel was constructed between 1996 and 1999 byTransfield-Obayashi Joint Venture. It was officially opened to traffic on 16 April 2000 with a temporary 60 km/h speed limit, and was free to use until 26 April.[1]
On 23 March 2007 just before 10am, three trucks and four cars collided in theBurnley Tunnel. The crash resulted in multiple explosions and a subsequent fire. This forced the evacuation of motorists from the Burnley Tunnel. The Domain Tunnel was closed and any drivers in the Domain Tunnel at the time drove out normally. Cross passage tunnels between the Domain and Burnley Tunnels were used by evacuees to exit from the Burnley Tunnel into the Domain Tunnel.[2]
In May 2007 a dramatic incident involving a truck and a sedan was caught by anA Current Affair film crew investigating the safety of the tunnel in light of previous events. Authorities are currently investigating if the crew, who were driving vehicles in the tunnel, may have contributed in instigating the crash.[3]
The Domain Tunnel is 1.6 km long and comprises 460 metres ofcut and cover tunnel at the west end, 680 metres of driven tunnel and 500m of cut and cover which includes a shallow river crossing. The western portal is shared with the longerBurnley Tunnel that carries traffic in the other direction.[4]Roadheaders were used to dig the bored section of tunnel, while at the eastern end the 170-metre final section of cut and cover was built under theYarra River, with acofferdam being moved as construction continued, permitting the river to keep flowing. The tunnel carries three 3.5-metre wide traffic lanes with 0.5-metre wide shoulders, and has two cross tunnels to the Domain Tunnel. The road level is a maximum depth of 40 metres, and has agradient of less than 2%.[4]
Regular radio transmission cannot be received while in the tunnel. Commercial stations have installed their own transmitters. A variable speed limit applies in the tunnel. In normal circumstances, the speed limit is 80 km/h. During maintenance, a 40 km/h speed limit applies and normal radio broadcast is regularly interrupted by announcements.
