The Olympiabrücke is a road bridge in Innsbruck that spans the tracks of the main train station and the Sill along the south ring (B 174) and thus connects the districts of Pradl and Wilten . It was built on the occasion of the Olympic Winter Games in 1964 and named after it.
history
On the occasion of the 1964 Olympic Games, a bridge was planned to directly connect Wilten and the train station with the sports facilities at Tivoli to relieve the city center . Construction began on August 22, 1962. The bridge was completed on November 27, 1963 and officially opened on January 3, 1964. The total cost amounted to 21.3 million shillings , of which the bridge cost 16.3 million and the ramps 4.7 million shillings. The Olympiabrücke forms the heart of the east-west connection, which was subsequently expanded and incorporated into the federal road network, which leads from the Innsbruck Ost junction of the Inntal autobahn into the Höttinger Au to the B 171 Tiroler Straße .
With increasing traffic, the three-lane Olympic Bridge increasingly became the bottleneck along the southern ring road. Therefore, it was expanded to four lanes from 2005 to 2006 with the elimination of the sidewalks on both sides. Instead, a new structure was built south of the existing bridge for pedestrians and cyclists. The cost of the foot-cycle bridge was around 2.5 million euros. The four-lane bridge was opened to traffic on April 13, 2006.

The structure of the road bridge is a prestressed concrete box girder with four fields and three main pairs of girders. The bridge is 287 m long, the total span is 249.7 m, the width 14.9 m. The ramp slope is 3% in the east and 5% in the west.
The foot and cycle path bridge is also a four-span steel box girder bridge with a length of 284 m and a width of 5 m. On the north side, the bridge is separated from the street by a steel parapet with inlaid vertical glass strips, on the south side it is secured by a glass railing with a steel curtain made of trapezoidal sheet metal. The staircase on the east side is architecturally designed with an exposed concrete beam.
