Abstract
The presented paper describes the overall design philosophy, the choice of construction technology and the construction itself of one of the longest bridge in Slovakia. The two post-tensioned prestressed concrete beam bridges with 30+ spans, with the largest span of 110,0 m are being built these days near the city of Žilina. Two separate bridge constructions are being built, each for one route direction.The bridge has been divided into four parts depending on different construction technology. The bridge cross section of technological parts Nr. 1, 2 & 4 consists of twin-T beam girder, whereas the part Nr. 3 is formed by box girder with continuously changed height of the cross-section.The overall width of the superstructure is the same for both bridges and equals 13,10 m. The superstructure is being built over dense area of the highway crossing, railway with frequent traffic and over the reservoir that serves as the energy source for water-based power station. Above the supports the cross-beams are designed with indirect support scheme. Internal post-tension prestress tendons are to be anchored in end cross-beams and in construction joints.
