The 30 years old Budapest –
Balatonaliga section of the M7 Motorway was
fully reconstructed in 1999-2002. The almost 100
bridges of the 80 km long section have been retro
fitted as well. The project was completed under the
continuous maintenance of traffic in three phases.
There are several different
types of bridges on the motorway: frame bridges,
multibeam decks, cast in situ hollow core slabs, box
section beam bridges, etc…The most frequent damages
were caused by the concrete corrosion, the soaking
of the structures due to insufficient insulation.
The bad condition of the curbs, the not code-conform
railings and the overall bad repair of the
structures and the surrounding including service
stairs, dranaige system and the slope linings was
problem as well. On the overpasses the insufficient
cross fall was increased with an extra concrete
Further part of the job was the design of 7
overpasses on the missing right carriageway of the
20 km long Balatonaliga-Zamárdi section. As these
bridges adjoin to the existing left-carriageway
bridges, the construction required special
considerations for each case.
