Niecodzienne problemy technologiczne realizacji przebudowy tymczasowego mostu drogowego na most stały na rzece Bug

In the paper authors presented very generally scope of reconstruction and strengthening of temporary road bridge over Bug river in Frankopol and focused in details on description of unusual technological aspects, which were design and applied at stage of bridge construction works. In particular authors shown technology of strengthening of supports and their foundations by means of micropiles, strengthening of spans by composite reinforced concrete slab, steel overlays, additional oblique trusses (struts) and external prestressing of lower chord of main girders as well as technology of all bridge lifting of 28 cm for the period of couple of month and technology of slab concreting. Reconstruction deserves for big attention because all works were carried out while keeping constant possibility for traffic flow across the bridge with token only weight limitation to 24 t.
