1,400-ton bridge moved without cranes

Austrian railway operator ÖBB has successfully relocated a massive railway bridge in Innsbruck without using traditional crane methods. The 1,400-ton structure was moved 100 metres as part of a major rail network modernisation.

The operation, completed late last week, used an alternative approach considered safer for the city’s dense urban environment.

Engineers first constructed the new Rauchmühle bridge near its intended location to limit disruption. Hydraulic presses lifted the structure before the relocation began.

Modular transporters roll bridge into position

On Sunday morning, January 18, teams began moving the bridge using self-propelled modular transporters (SPMTs). Twelve units carrying 56 axles and 112 wheels supported the massive load.

The structure travelled across Hallerstraße at speeds of 1-2 kilometres per hour, allowing operators precise control throughout the delicate manoeuvre.

Concrete replaces worn metal structure

The original metal bridge had served the route for more than 60 years but reached the end of its operational life. Daily traffic of around 270 trains combined with Alpine weather conditions caused extensive wear.

Officials chose concrete for the replacement to reduce noise pollution and extend the bridge’s lifespan.

Work continues on final installations including supports, bearings and railway equipment. The line is expected to resume service by month’s end.
