The Szövő Street road bridge over M7
Motorway at Érd was reconstructed in 2002. The
35 years old three span continuous R.C. box beam
bridge showed big deflections and a lot of cracks.
Beyond the full-scale reconstruction of the bridge,
external prestressing was used in order to reduce
the above faults and to improve the long term
serviceability of the bridge.
