Location and history

The Steyregger Bridge is located immediately north/upstream of the older Steyregg railway bridge. On the Steyregger Ufer the distance between the centers of the bridge is around 75 meters, on the Linzer Ufer it is only 30 meters. [1]

It connects Linz in the west with Steyregg in the east of the Danube River, which flows south-southeast. It is part of Donau-Straße (B 3) and has 2×2 lanes that are separated from each other and from the side sidewalks and cycle paths by guardrails. On the Linzer Ufer, the B 3 separates the operating areas of the Linz Chemical Park from the voestalpine Hütten- und Stahlwerke. [1]

It was opened on September 12, 1979, after three years of construction. The first plans to build the road bridge were already in 1914. [1]

Construction

The 453.6 m long and 254.86 m wide bridge has an A-shaped, 44 m high pylon, which is articulated on the cantilever arms of the pylon cross beam on the stream pillar. Its head is braced to the carriageway support with two cables on each side. It has five openings with spans of 50.6 + 161.0 + 3 × 80.6 m, with which it bridges the edge of the bank of the industrial area, the main channel of the Danube, its edge areas and the flood zone.

Its' bridge deck is a composite construction made of four steel solid wall girders and a 20 cm thick reinforced concrete slab. [2]

The bridge was built on behalf of the Upper Austrian state government in a joint venture between the construction companies Hamberger Baugesellschaft, Mayreder Krauss & Co and Porr AG in collaboration with VOEST-Alpine. The planning and construction management was carried out by Waagner-Biro. [3]

<span class="mw-page-title-main">Transmission tower</span> Structure used to support an overhead power line

A transmission tower is a tall structure, usually a lattice tower made of steel that is used to support an overhead power line. In electrical grids, transmission towers carry high-voltage transmission lines that transport bulk electric power from generating stations to electrical substations, from which electricity is delivered to end consumers; moreover, utility poles are used to support lower-voltage sub-transmission and distribution lines that transport electricity from substations to electricity customers.

<span class="mw-page-title-main">Overhead line crossing</span> Crossing of an immovable obstacle by an overhead power line

An overhead line crossing is the crossing of an obstacle—such as a traffic route, a river, a valley or a strait—by an overhead power line. The style of crossing depends on the local conditions and regulations at the time the power line is constructed. Overhead line crossings can sometimes require extensive construction and can also have operational issues. In such cases, those in charge of construction should consider whether a crossing of the obstacle would be better accomplished by an underground or submarine cable.

It is 1,614 meters (5,295 ft) long, of which the pontoon section is 1,246 meters (4,088 ft) long. The cable-stayed section consists of a single 99-meter (325 ft) tall H-pylon which has a length of 368 meters (1,207 ft) and a main span of 172 meters (564 ft). This allows for a clearance of 32 meters (105 ft).

<span class="mw-page-title-main">Extradosed bridge</span>

An extradosed bridge employs a structure that combines the main elements of both a prestressed box girder bridge and a cable-stayed bridge. The name comes from the word extrados, the exterior or upper curve of an arch, and refers to how the "stay cables" on an extradosed bridge are not considered as such in the design, but are instead treated as external prestressing tendons deviating upward from the deck. In this concept, they remain part of the main bridge superstructure.
