Politics · Infrastructure debate
Almost everyone in the Bundestag agrees that Germany's roads, bridges, railways and waterways need renewing. The argument is about how much to spend, where the money comes from, how fast projects may be approved and what may be traded away for speed. This page sets out that debate and where Steffen Bilger stands in it.
Argument map
The infrastructure debate splits into four separate arguments. For the physical systems themselves, see Road infrastructure, Rail infrastructure and Bridges; this page is about the politics.
How should Germany renew its transport infrastructure, and who pays?
Ageing bridges and an overloaded rail network. Little dispute about the diagnosis; much about the order of work.
Section BRecord investment via borrowing, while the regular transport budget shrinks.
Section CBilger's "paradigm shift": multi-year funding outside the annual budget cycle.
Section D"Overriding public interest" for transport projects, against nature-protection objections.
Section ESection B — the backlog
Germany's federal transport networks were largely built in the post-war decades and are now reaching the end of their design lives at the same time.
According to Die Autobahn GmbH, about 55 per cent of the bridges on federal trunk roads were built before 1985, and about 4,000 bridge structures on a heavily used core network of some 7,000 km need modernisation, with 2030 as the target year. A Bundestag report on findings by the Federal Audit Office put progress in 2024 at 69 of a planned 280 sections. In June 2026 a Rhine bridge in Bonn was closed indefinitely over cracks and corrosion; the then minister, Patrick Schnieder, warned that this "can keep happening to us".
On the railways, Deutsche Bahn's subsidiary DB InfraGO planned general renovations of about 40 heavily used corridors by 2036. In September 2026 DB's chief executive Evelyn Palla said the pace would drop from four corridors a year to two or three, leaving the end date open.
The diagnosis is broadly shared across parties. The disputes are about priorities: whether to repair first or also build new; whether rail or roads should get more; and whether closures that disrupt commuters for months deliver enough.
Bundestag, 8 September 2026: the implementation of the corridor renovations muss erheblich besser werden
("must get considerably better", translation). Der Spiegel, 26 September: Man kann niemandem erklären, warum Pendlerstrecken so lange gesperrt werden und die Situation danach noch immer nicht besser ist.
("No one can explain why commuter lines are closed for so long and things are still no better afterwards.")
The first completed corridor, the Riedbahn between Frankfurt and Mannheim (closed in the second half of 2024), was reported by DB InfraGO to have cut disruptions by about 60 per cent, short of the 80 per cent target. The corridor model was set up before Bilger took office.
Section C — the money
Both sides of the budget debate quote accurate figures. They simply count different pots of money.
Up to €500 bn of borrowing over 12 years for infrastructure and climate neutrality; adopted Sept 2025, retroactive to 1 Jan 2025.
€21.3 bn in the 2026 plan, including €16.3 bn for rail maintenance and €2.5 bn for digital signalling (ERTMS).
€17.7 bn, still the largest single share of the fund's €54.9 bn plan.
Ministry budget falls from €27.9 bn (2026) to €26.43 bn (2027 draft); core investment from €13.48 bn to €12.76 bn.
| Item | 2026 | 2027 draft | Scale (2026 → 2027) |
|---|---|---|---|
| Core budget expenditure | 27.90 | 26.43 | |
| Special fund, transport | 22.0* | 17.72 | |
| Investment in core budget | 13.48 | 12.76 | |
| Autobahn GmbH investment | 4.26 | 4.36 | |
| Federal rail lines (core) | 2.69 | 3.00 | |
| Federal waterways (core) | 1.82 | 0.85 |
About €170 billion for transport investment up to 2030; rail funding up by €300 million in 2027 and €1.8 billion in total by 2030. Special-fund money means auch Schleusen und Wasserwege können endlich saniert werden
("locks and waterways can finally be renovated too").
The budget has roughly halved, from about €50 billion to €26 billion; there is not enough for investment, and no new rail projects can start next year.
Only about €10.2 billion of investment remains in the core budget; he saw "neither transparent nor sustainable financing concepts" and called the change of minister a "political farce".
Wanted more money for motorway repairs and criticised about €11 billion for roads against €20 billion for rail: "nothing gets better with this coalition".
The opposition arguments are paraphrased from the Bundestag's own report of the debate. ZDF and Logistik Heute noted in July 2026 that the special fund concentrates on maintenance and that core-budget gaps of billions open from 2028, leaving new projects underfunded. Detailed figures are on Infrastructure investment.
Section D — the financing model
Bilger's most concrete infrastructure initiative so far is a change to how the motorways are financed.
Die Autobahn GmbH des Bundes, the federally owned company that has run the motorways since 2021, receives its money through the annual federal budget. Critics of this model have long argued that it makes multi-year construction programmes hard to plan, because funding can change every year.
In his budget speech on 8 September 2026 Bilger announced that the coalition had agreed a draft law on the company's ability to borrow, calling it ein Paradigmenwechsel in der Modernisierung und Finanzierung des Straßenbaus
("a paradigm shift in the modernisation and financing of road building", translation). Financing should become überjährig, flexibel und verlässlich
("multi-year, flexible and reliable"). The cabinet approved the bill on 7 October 2026.
Cabinet decision, 7 October 2026 (press release 093/2026). The bill now goes to the Bundestag; it is not yet law. The ministry reports Bilger saying it creates "more room for investment" and that whatever is ready to build will be built.
Any borrowing by a federal company raises questions about the constitutional debt brake and about privatisation, which were contested when the company was founded. Specific parliamentary objections to this bill had not been documented by the date of this page; the debate in the Bundestag is still to come.
Section E — planning speed
The main planning-acceleration law was passed before Bilger took office. His contribution so far is support for it, not authorship.
The Infrastruktur-Zukunftsgesetz (Infrastructure Future Act) was passed by the Bundestag on 26 June 2026 and approved by the Bundesrat, the chamber of the Länder, on 10 July. According to the federal government, most provisions took effect on 29 July 2026 and the nature-conservation changes on 1 February 2027. It gives transport projects such as closing gaps in the network, rail expansion, road and bridge projects, ports and waterways the legal status of being in the "overriding public interest", which weighs heavily when authorities balance them against other interests. It also makes planning procedures digital-only, removes environmental assessments for rail electrification on routes under 60 km, and allows nature compensation to be made through payments instead of physical measures.
Speaking to Der Spiegel on 26 September, Bilger said Wir waren viel zu langsam bei der Planung, die Prozesse waren langwierig
("We were far too slow in planning; the processes were lengthy", translation) and backed acceleration laws of this kind.
Unter dem Deckmantel Beschleunigung plant die Koalition nichts anderes als einen Generalangriff auf die Natur.
"Under the guise of acceleration, the coalition is planning nothing less than a general attack on nature." (translation)
Olaf Bandt, chair of BUND
Einmal zerstörte Natur ist unwiederbringlich verloren, rein finanzielle Kompensation ändert daran gar nichts.
"Nature once destroyed is irretrievably lost; purely financial compensation changes nothing." (translation)
Sascha Müller-Kraenner, Deutsche Umwelthilfe
The umbrella group DNR, through its president Kai Niebert, argued that money alone does not keep landscapes intact and water clean. BUND said the "overriding public interest" status was being used inflationarily.
Associations and partners
Associations' demands since Bilger took office, as reported. They show the pressure on infrastructure policy from several directions at once.
A rolling Infraplan, more capacity (and no €145 m cut to rail freight in 2027), reform of track-access charges, digitalisation and the digital coupling, and stronger federal steering of DB. On 6 October it called the Infraplan "the start of a system change" but missed a rail infrastructure fund.
The transport companies' association and the German Transport Forum criticised the 2027 cuts as weakening reliability and planning security for rail freight (as paraphrased by VerkehrsRundschau).
Chair Lukas Iffländer called for delays to count from three minutes, as in Switzerland, rather than six, and for cancelled trains to count as late.
In the budget debate Isabel Cademartori praised investment at a record level. On his appointment she had said there was "really no time for a long settling-in period".
