The paper describes the rebuilding of multi - span, continuous, composite bridge, located along road nr 975 over Dunajec River in Zakliczyn city (Małopolska Voivodeship). The investment is implemented in “design - build” system and BANIMEX Sp. z o. o. is a main contractor. The investement was divided into two stages. This paper presents the second one, where the main task was to strengthen the structure and replace the equipment including road surface. A project of the second stage was delivered by the design office PROMOST Wroclaw sp. z o.o. Sp. k. The paper focuses on strengthening of steel - concrete composite bridge structure. The analyses of several solutions ware performed. The designer in cooperation with the main contractor and investor decided to apply strengthening in the form of three main technical components: 1) new composite reinforced slab, 2) passive strengthening: steel sheets on the bottom of the girders flanges and longitudinal ribs in the area of a bridge piers, 3) active strengthening: external post-tensioning using straight cables.

Prefabrykaty zastosowano w czasie remontu najdłuższego kamiennego mostu kolejowego w Polsce, mającego długość 489,0 m. Wykorzystano 59 różnych typów prefabrykatów o indywidualnych gabarytach. Wszystkie elementy wykonano w niemieckich wytwórniach w Plauen, a wbudowano w Polsce. Dlatego zarówno zbrojenie, beton, jak i same prefabrykaty musiały spełniać wymagania przepisów niemieckich i polskich.

Authors presented application of precast concrete elements during refurbishment of bridge in km 37.221 of railway no. 282 over Bóbr River and bypass of Bolesławiec. Construction works were realized on the longest railway stone bridge in Poland, which length is 489,0 m. There was a necessity to use 59 different type of precast elements, with various dimensions, from 1 to 192 pcs. of each type. Overall 518 pcs. of precast elements were realized and embodied. All elements, including reinforcement, were realized in German plants in Plauen, and used in Poland, so rebar, concrete as well as precast elements itself have to fulfilI both German and Polish requirements.
