At the threeway “Funkturm” traffic junction in Berlin, one of Germany’s most heavily transited motorway sections, the two HABAU GROUP companies HABAU and MCE will be completing new construction of the Ringbahn and the Halenseestraßen bridges. The investment sum is around 50 million euros net.
Work on the replacement construction of the 200-metre-long Ringbahn bridge at the A100 in Berlin will begin in September 2025. In a tendering procedure held Europe-wide, the consortium consisting of the HABAU GROUP companies HABAU Hoch- und Tiefbaugesellschaft m.b.H. and steel construction company MCE GmbH beat the competition and was awarded the contract by DEGES Deutsche Einheit Fernstraßenplanungs- und -bau GmbH. Alongside the price, crucial factors were the short construction time and the low negative impact on railway traffic. Completion is planned to take place in under two years.
The work includes the replacement construction of the Ringbahn bridge and the Halenseestraßen bridge. Additionally, the consortium will be erecting new support walls. The official groundbreaking is foreseen for the second half of October.
“We’re pleased to have been awarded the contract for this important bridge project, to which two of our Group companies – HABAU and MCE – are able to contribute their strengths”, stated Hubert Wetschnig, CEO of the HABAU GROUP. “With our many years of experience in bridge building and the concentrated expertise within our ‘construction family’, by reconstructing the Ringbahn bridge we’re ensuring the efficiency of a central hub in Berlin while also reinforcing our position in the German market in the long term.”
Early replacement construction: project overview
As part of the A100, the Ringbahn bridge, built in 1963, was originally designed to bear a load of 25,000 vehicles each day. Since it was put into operation, the volume of traffic has continually increased and was most recently at around 90,000 vehicles per day. This huge strain accelerated the ageing process of the bridge to the extent that it had to be closed at short notice and torn down in April 2025 due to its poor constructional state. In its place, a modern, 200-metre-long steel composite bridge will now be erected, one that will be able to safely absorb the high volume of traffic in future once more. In parallel to this, the Halenseestraßen bridge will be reconstructed as a prestressed concrete structure.
The particular challenge of this project is completing the reconstruction as swiftly as possible with as little impact as possible on residents, road users and railway traffic. The new Ringbahn bridge will use state-of-the-art technology and will provide a noticeable increase in quality of life in the surrounding area thanks to additional noise protection measures.
The fact it is situated above several railway lines and the massive traffic volume present special challenges for planning and construction. Thanks to close cooperation within the consortium and with the client and Deutsche Bahn, construction processes and technical solutions can be precisely coordinated and efficiently implemented.
Synergies that enable large-scale projects
The competences within the HABAU GROUP interlock in an ideal way: HABAU is in charge of reinforced concrete construction along with earthworks and road construction and the overall technical coordination of the project, while MCE takes on steel construction. This close intermeshing creates synergies that ensure an efficient workflow and top quality in the shortest time – a crucial success factor in this major project.
HABAU GROUP continues to expand presence in German infrastructure market
With the contract for the Ringbahn bridge, the HABAU GROUP is further expanding its successful project history in Germany. The company has already been involved in significant infrastructure projects in the past, including the expansion and general renovation of the “Havelland Motorway” near Berlin by 2022 and the current renovation of the 453-metre-long “Rahmede Viaduct” in North Rhine-Westphalia.
