The Tetőfedő Street pedestrian
bridge over M7 Motorway at Érd was
reconstructed in 2002. The 35 years old two 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. |
