Hungarian railway bridge installation in one weekend: SPMT lessons for engineers
Reviewed by Joe Ashwell
First reported on New Civil Engineer
30 Second Briefing
Dutch heavy lifting specialist Mammoet installed the first of two steel bridge structures for Budapest’s new Közvágóhíd railway crossing over a single weekend using self-propelled modular transporters (SPMTs). The preassembled span was driven into final position on SPMT lines rather than launched or lifted by crane, minimising possession time on this busy urban rail corridor. For contractors, the operation illustrates how SPMT-based bridge moves can compress rail blockade windows and reduce temporary works demands on constrained city sites.
Technical Brief
- Using SPMTs removed the need for large crawler cranes, reducing lifting risk near live urban assets.
- Preassembly off-line minimised work at height over tracks, cutting fall and dropped-object exposure.
- Approach is directly transferable to brownfield rail bridges where crane radii or foundations are heavily constrained.
Our Take
Mammoet’s role at the Közvágóhíd railway bridge in Budapest sits alongside its heavy-lift work on the 4,200‑tonne Clifton railway bridge over the M6 in the UK, signalling that rail bridge replacement using large SPMT moves is becoming a repeatable method across European networks.
Across our infrastructure coverage, Mammoet increasingly appears on complex, time‑critical jobs (from BHP’s Jansen potash headframes to major UK bridge lifts), which suggests Hungarian rail clients are tapping a contractor base experienced in minimising possession windows and disruption.
With New Civil Engineer also curating the NCE Bridges Awards and promoting ideas like a National Bridge Retrofit Library, the Közvágóhíd project is likely to be benchmarked against UK best practice on rapid bridge replacement and safety management rather than treated as a purely local Hungarian scheme.
