description
The built in the years 1965-1967 Danube bridge Grein was the first in cantilever built prestressed concrete bridge over the Danube in Austria. The construction of the Danube bridge was the largest post-war construction site in the region at the time.
The 252 m long and 11.5 m wide bridge has an 8.1 m wide carriageway with two lanes and marked cycle lanes as well as 1.7 m wide walkways.
It has three openings with pillar spacing of 73 + 106 + 73 m. Its superstructure consists of a single-cell, 6.9 m wide, slightly haunched box girder with a rectangular cross-section, the height of which increases from 2.42 m at the abutments to 4.63 m above the pillars. The straps and bars also have variable thicknesses. The prestressed concrete box girder was constructed from the two pillars using the Dywidag system in cantilever construction . The pillars stand on concrete foundations, which were established on the natural rock with the help of a caisson . They were clad with granite stones to protect them from the ice drift and to give them a more pleasing appearance.
The bridge opened on September 24, 1967.
The daily average of the traffic over the Danube bridge in the counting year 2010 (number of vehicles in both directions) was 4,310 vehicles (of which 3,994 in passenger traffic and 366 in freight traffic).
The bridge was extensively renovated between 2014 and 2016.
The bridge has a passage opening for downhill and uphill journeys with a width of 100 m and a height of 8.31 m above HWS 2010 (highest shipping water level).
