Brenner’s €10.5bn tunnel faces an 11-year gap

The first continuous tube of the Brenner Base Tunnel now runs 55 kilometres from Innsbruck in Austria to Fortezza in Italy, after a boring machine completed the final stretch on 25 August (South Tyrol, ANSA). When trains start running, around 2032, this will be the world's longest underground railway link. It cost €10.5 billion, with the EU contributing €2.3 billion (CINEA). The economic test is whether Europe can finish the freight corridor around the tunnel before the tunnel opens.

A flat track under a steep pass

The old Brenner railway climbs gradients of 24–27 per mille, steep enough that freight trains need extra locomotives and carry less weight (BBT SE). The new tunnel runs nearly flat, at 4–7 per mille. That lets trains be longer and heavier, cutting Innsbruck-to-Fortezza from 80 minutes to about 25 (CINEA, Webuild). In freight economics, flatter track means rail can compete with trucks on speed and cost per tonne.

The demand is there. More than 2.5 million trucks cross the Brenner Pass each year, and rail handles only about 27% of cross-border freight on this corridor (CINEA, Bezirksjournal). Three quarters of goods still move by road. A tunnel that makes rail faster and cheaper has a market, if the tracks on either side can feed it.

They cannot yet. Germany's northern access route from Munich through Bavaria has not started construction. Berlin's transport ministry sent planning documents to the Bundestag in July 2026, leaving parliament to decide whether to proceed (BMV). Bavarian reporting puts construction starting in 2034 and trains running in 2043 (rosenheim24, BR24). If the tunnel opens in 2032, that is an eight-to-eleven-year gap where Europe's most expensive Alpine crossing sits below full capacity because Bavaria's tracks aren't built. Germany's access alone carries an estimated price tag of around €16.2 billion (n-tv, Spiegel).

Italy's southern side is further along. RFI, Italy's rail network manager, has the first Fortezza–Ponte Gardena lot under construction, worth over €1.5 billion (RFI). But the full Fortezza–Verona upgrade is incomplete: the Rovereto bypass remains at design stage (Daily Alpine). Italy has started; it has not finished.

Switzerland already tried this

Europe has a test case. Switzerland opened its Gotthard and Ceneri base tunnels and paired them with strong policy incentives to push freight off roads. Rail's share of Swiss transalpine freight reached about 70% by end-2024. That is high, but it has slipped 2.6 percentage points since 2022. Some 960,000 trucks still crossed the Swiss Alps, well above the legal target of 650,000 (admin.ch, SRF). Swiss authorities blame construction works on access routes and lack of diversion capacity. A flat tunnel and a government committed to rail still aren't enough if the connecting lines can't keep up.

Who gains, who waits

Northern Italian exporters and logistics firms stand to gain from faster, more reliable rail. The Italy–Germany lane alone carries over 220,000 full truckloads annually (Contship Italia). Tyrolean communities choking on lorry pollution gain only if policy also shifts traffic off the road once rail capacity arrives. Long-haul road hauliers whose margins depend on cheap Alpine transit, and taxpayers carrying cost-overrun risk on both sides, bear the adjustment cost.

The EU itself captures the tension. Brussels co-funded the tunnel to shift freight to rail. Yet in case C-524/24, the Commission intervened on Italy's side against Austria's truck restrictions on the same corridor (Curia, Trasporto Europa). Austria wants to restrict trucks now; the Commission argues such restrictions obstruct EU trade while rail capacity isn't ready. An Advocate General recommended in July 2026 that Austria's bans violate EU free-movement law (Logifie). Europe is building the rail alternative and protecting the road status quo until rail works. The contradiction only resolves if the corridor comes together.

The tunnel cannot deliver the shift by itself. Whether five countries can coordinate two decades of access-route construction into one working freight corridor will determine whether €10.5 billion buys a transport revolution or a stranded piece of engineering waiting for the railway to catch up.
