There are several viaducts along the new section of
the M7 Motorway between Balatonszárszó and
Ordacsehi. The S.16. Viaduct at Balatonszárszó
(sta 125+752 km) was built in 2004, according to the

divided by a gap. The substructers are hollow
section piers founded with dia 1,20 m bored piles.
The multispan continuous superstructures were
incrementally launched with the aid of a steel nose.
The parallel construction cables are grouted
internal cables, while the additional cables for the
final stage are unbounded external ones with double
protection, led in the inner of the box girders on
deflection saddles. The bridge is straight in plan,
the longitudinal grade is 0,61%.
