Správa železnic will Repair a Bridge on the Line Rumburk - Sebnitz
The bridge with seven openings is 217.3 metres long and dates from 1904. The first and the seventh opening have a stone arch construction; the second and the sixth one have a steel truss construction. The maximum height of the bridge over the valley is 34 metres. After 116 years of operation, the steel components especially are at the end of their life cycle. That is why Správa železnic opted for a reconstruction so that the line can continue to serve for commuting to work, to school and to excursions. The new bridge will not change the land shape in any way; it will consist of a steel truss welded construction in the same shape and with similar dimensions as the original ones.
The stone granite masonry of the bridge pillars will be fully cleaned, re-jointed and fortified by grouting to ensure further durability of the lower construction masonry. For placing a new steel bridge deck, reinforced concrete pier caps will be built on the pillars. The current stone arches will be saved in the same way as the connected lower construction (the pillars). Due to unsatisfactory obstruction clearance, a reinforced concrete transition slab with ledges will be placed on the arches to allow placing the railings in the required distance from the track axis.
The railway superstructure will be exchanged in the necessary extent; the railway substructure will remain preserved. The bridge reconstruction will require necessary restrictions in railway operation. Construction of new pier caps will be carried out within two-days closures planned for weekends during the period from 16 May up to 28 June. A continuous closure in railway operation for 91 days from 1 September to 30 November this year will be necessary for exchanging the bridge deck.
