The tunnel is part of an ongoing series of works to reduce congestion on the mittlerer ring. Cost to the city: 25 million euros.
The effnertunnel is 102 metres long (which equates to €245,000 per metre..).
However, we can still expect ongoing delays on this section of the ring - the main Richard-Strauss tunnel (1500m long) will not open until 2009.
The area above the tunnel will eventually be home to the massive statue entitled "Mae West", by sculptress Rita McBride.
The first tunnel to be built in this series of works, the petueltunnnel, which runs along the north side of the city, has since become a notorious accident-hotspot.
