Rehabilitation and strengthening of Sylva Bridge at Kungur, Russia

Sylva Bridge at the downtown of city Kungur is one of the oldest road bridges in Perm region, the West Urals, Russia. Its erection was begun in 1912 and was interrupted with the First World War and the further events in Russia. The bridge was opened only in 1931. For 75 yeares of bridge operation the most part of bridge constructions have been acquired plural damages, both mechanical and corrosion. After the bridge inspection in 2003 and according to the calculations of its capacity, the decision on reconstruction of the bridge was accepted. The purpose of rehabilitation was to replace the timber deck by steel orthotropic deck with asphalt pavement. A new deck was to be engaged in combined action with the existing metal structures with the help of socles with highstrength bolts. Due to this, the bridge carrying capacity was to be increased as required with the modern standards. In 2006, after tests, the bridge was opened for traffic.
