A late-afternoon photo of the traffic on Pfaffenberg-Zwenberg (Pfaffen-hill - Zwen-hill) bridge. Long freight train passes over the 100m deep gap. It was built (the bridge) from 1969 to 1971, at the time this was the biggest ferro-concrete bridge of the world. It has a span of 200m(656 feet), it's 377m long and 10m wide. It was built for the purpose that trains could climb the Tauern south-ramp in less than half-an-hour (33 km).
