Dillinger steel builds bridges
New Moselle bridge built with heavy plate
steel in various qualities
The new Moselle bridge in the Rhineland Palatinate of Germany has been opened to public traffic in November
2019. German steel company Dillinger played a major role, with more than 25,000 t of heavy plate provided for
the construction of the bridge.
Crossing the valley of the Moselle
river, this new bridge is one of the
highest and longest in Germany.
The height of the piers and spans reaching
up to 210 metres required a multitude
of planning, assembly and organizational
innovations in order to complete
the beam bridge. The highest pier measures
about 150 metres, the lowest about
20 metres. The distance between the
piers ranges from 105 to 210 metres.
The structure’s height of 160 metres
exceeds even that of the Cologne Cathedral
and its length, at 1.7 kilometres, is
six times the length of the London
Bridge.
Dillinger steel was selected for the
project due to the special dimensions
and the associated requirements for the
building materials used. For individual
elements such as piers and substructures,
Dillinger supplied heavy plate
steel in various qualities and in thicknesses
ranging from 8 to 125 millimetres.
Much of the steel was delivered to
the construction site from Dillingen by
barges via the Saar and Moselle rivers
– an environmentally friendly option, as
it seems natural for building a river
bridge.
The Moselle bridge is the centrepiece
of a 25-kilometre section of the new dual
carriageway construction project for the
new Bundesstrasse B50 major road in
Western Germany. The bridge enables
vehicles to drive through what was formerly
described as “Europe’s most
expensive dead end.” The B50 is intended
to facilitate the road traffic between
Luxembourg, the Belgium and Dutch
deep water sea ports and the greater
Frankfurt area. At the regional level, the
Eifel and Hunsrück regions in Germany
are now connected via the A60 autobahn
and the B50 Bundesstrasse.
