The reconstruction of the bridge on the 9,531 km Čerčany – Skochovice line was completed on 12 November. The bridge – with a single-track non-electrified railway line – spans the Sázava River in Týnec nad Sázavou. The reconstruction was co-financed by the EU Cohesion Fund under the Operational Programme Transport. The construction’s investor was the Czech Railway Infrastructure Administration (SŽDC).
The two-span railway bridge built in 1896 no longer met the current railway operation requirements and had to be completely reconstructed. After reconstruction, the bridge now satisfies the required structure and loading gauge.
The reconstruction as such started in October 2012. It was carried out in difficult conditions for laying foundations in the Sázava riverbed and was being dealt with in three stages – railway superstructure, bridge reconstruction and relaying of Czech Railways – Telematika’s communication cable. After dismantling the railway superstructure, the current steel construction was removed and the middle pillar and a part of the abutments were demolished. It was followed by concrete work on new pier caps, micro-pile laying of the pillar, concrete work on foundations, shaft and pillar bearing shelf and a stone facing of the pillar shaft.
The new steel construction consisting of truss girders and an orthotropic slab was welded on the spot into a single unit, inserted into the aperture and equipped with bridge closures. The communication cable of Czech Railways – Telematika was transferred, new continuous ballast was laid as well as new railway superstructure and the bridge’s transition area. Small completion works took place during spring and summer of this year.
The project was co-financed by the European Union from its Cohesion Fund under the Operational Programme Transport with support amounting up to 77.52% of eligible costs. Domestic financing was provided by the State Fund for Transport Infrastructure. The construction supplier was the association of companies Chládek a Tintěra, Pardubice a.s., Porr a.s. and Mostostal Kielce S.A.
