Securing Europe’s mobility for tomorrow

Europe’s transport networks are in need of refurbishment. STRABAG modernises roads, bridges and railways in a sustainable manner to ensure that mobility runs smoothly and that the infrastructure can reliably meet the demands of tomorrow.

Our contribution to sustainable mobility

Roads will remain a key part of mobility in Europe. But the backlog of infrastructure repairs is enormous. In Germany alone, around 25,000 kilometres of long-distance roads need to be repaired or renewed. STRABAG works with clients on resource-efficient solutions such as asphalt recycling to keep raw materials in circulation on a large scale. We are also advancing innovative mobility concepts, for example by testing inductive charging systems for electric vehicles together with Electreon. Modern, connected transport infrastructure is an important foundation for the sustainable mobility of tomorrow. Take, for example, the new U5 subway line in Hamburg, which - with its fully automated operation - is set to become a key element of the mobility transition in the Hanseatic city: STRABAG subsidiary ZÜBLIN is playing a leading role in the construction of one of Germany’s largest ongoing public transportation infrastructure projects.

At a glance

  • Need for infrastructure regeneration

    According to government figures, just over 17,000 kilometres of railway track, 18,000 bridges and just under 25,000 kilometres of motorways in Germany are in urgent need of repair.

  • Planned investment drive

    The German Government has announced an investment drive for infrastructure and climate neutrality in Germany and intends to set up a special fund totalling 500 billion euros, spread over twelve years, to finance this.  
     
    According to the plan, more than 34 billion euros are to be invested in roads, railways and waterways in 2026 alone.

  • Outdated waterways

    More than half of the flood defences and around 60 per cent of the lock systems on German waterways were built before 1950 and are now reaching their technical limits. (Source)

Making mobility more sustainable:

People and goods should continue to be transported reliably, safely and in a climate-friendly manner in the future. This requires new approaches to the construction, refurbishment and operation of infrastructure. These examples illustrate what sustainable mobility looks like in practice.

Railway refurbishment between Hamburg and Berlin

On behalf of Deutsche Bahn subsidiary DB InfraGO, we have carried out a comprehensive and sustainable upgrade of the vital Hamburg–Berlin rail link. The modernised route will help ensure reliable rail services for many years to come.

Modular bridge construction

The STRABAG modular bridge integrates design, fabrication, transport and assembly into one seamless process. The result: greater efficiency and quality, with shorter construction times.

U5 Hamburg

The new U5 in Hamburg is being built in accordance with a CO₂ reduction plan that is reviewed on a regular basis. The aim is to reduce CO₂ emissions during the construction of the underground line by 70 per cent compared with conventional construction methods.

Concrete Building Materials Depot

Sustainable road construction depends on reusing construction materials. On Austria’s A2 motorway, we are rehabilitating an eleven-kilometre stretch of concrete carriageway and recycling not only concrete and asphalt, but also sand for the first time.

Conserving resources through the recycling of excavated material

Around 1.1 million cubic metres of soil are being moved as part of the A8 upgrade near Pforzheim in Germany – an enormous volume that is being almost entirely reused.

Alternative powertrains

HVO diesel, hydrogen or electric power – STRABAG is already using these climate-friendly drive technologies.

  • Modernising our roads, bridges and railways is one of the most important tasks of our time. High-performing transport infrastructure strengthens business locations and creates the conditions for sustainable mobility. As a technology leader in transport infrastructure construction, STRABAG is actively shaping this transformation and delivering major infrastructure projects – including on the Hamburg–Berlin railway line.

Frequently asked questions about sustainable mobility

  • What is sustainable mobility? 

    Sustainable mobility means moving people and goods in ways that reduce environmental impacts and conserve resources while meeting economic and societal needs. It includes climate-friendly modes of transport, high-performing infrastructure and innovative technologies. 

  • Why is transport infrastructure so important for sustainable mobility?

    Mobility depends on safe, high-performing roads, bridges and railways. Modernising and maintaining existing transport routes can improve traffic flows, reduce congestion and make more efficient use of resources. Sustainable mobility therefore starts with infrastructure that is fit for the future.

  • Why is upgrading existing infrastructure often more sustainable than new builds?

    Modernising existing roads, bridges and railways makes use of structures that are already in place and often saves materials, energy and land. At the same time, infrastructure can be adapted to current requirements and made more efficient and resilient over the long term. 

  • What role does public transport play in the mobility transition?

    Attractive public transport reduces pressure on roads, lowers emissions and provides an efficient alternative to private car use. Investment in modern underground, tram and rail networks is therefore an important building block for sustainable mobility. 

  • What role does the circular economy play in transport infrastructure construction?

    The circular economy is about keeping materials in use for as long as possible. In transport infrastructure construction, asphalt, concrete, excavated material and other construction materials can be processed and reused. This conserves resources and reduces waste.

  • How does STRABAG contribute to sustainable mobility?

    STRABAG develops and delivers infrastructure projects that combine sustainability with performance. This includes the rehabilitation of roads and railway lines, resource-efficient recycling solutions, innovative bridge concepts and support for climate-friendly mobility projects. The aim is to create infrastructure that remains efficient, resource-conscious and future-proof over the long term.
