The lowest bridge clearance on the Danube is 6.8 meters, at Novi Sad, Serbia. Drumsko-železnički most (road-railway bridge) was built in 2000 to replace the previous railway bridge after it was bombed by NATO in 1999. It is a one-lane bridge, used alternately by trains or heavy trucks. A replacement for this bridge is under construction (note the crane barges in this 2014 photo) however it remains uncompleted as of June 2016.
