Extension of the Smuuli roadSmuuli road - Suur-Sõjamäe str, Tallinn

The viaduct of Smuuli road connects Smuuli road from Peterburi road up to Suur-Sõjamäe street. The viaduct with the length of 370 m was built over the railways first in Estonia as the guy bridge within 170 m and as the five-opening girder bridge within 200 metres. The width of the lanes of the viaduct is 3.5 m and the width of the light traffic road is 4 m. Also the viaduct, established in the construction of the extension of Smuuli tee where we used the novel technological solution, is unique. 370 m long viaduct in ferro and prestressed concrete construction consists of three parts: the first part is the 120 m long girder bridge with three openings, 170 m long guy bridge in the middle and the second part is again 80 m long girder bridge with two openings. The 40 m long prestressed concrete girders of girder bridges were cast at site in this zone that in lifting with two cranes one lift was needed for the installation of the girder. 42 m parts remaining to the side of the girder bridges made of ferroconcrete pylons of the guy bridge were cast with the planking supported from the land. The part crossing the railways with the opening of 85 m was cast with the shiftable suspension planking by pylons by stages of 7.6 m long to the middle. Two of the suspended planking wear the steel frame which were anchored to the previous part of casting, whereas the planking of the next part and its carriers were installed only after the petrification of the concrete of the previous part and stretching of the retightening cables.
