An estimated 58,240 people packed the Linz riverside on Sunday for what officials called Austria’s largest civic hearing, turning a once-obscure municipal procedure into a huge public challenge to a proposed €1.46 billion (about $1.72 billion) road tunnel. The crowd stretched for more than a kilometre along the Danube, with people following proceedings on screens in nearby parks.
The hearing began with an unlikely discovery. Adriana Neri, a 63-year-old retired municipal clerk, said she bought a battered civic handbook at a charity book sale in February and spotted a provision requiring the city to hold an open assembly if residents submitted 15,000 verified signatures.
The clause no one expected
City legal staff confirmed in May that the provision, printed in a 1921 local-government handbook, remained in force. Neri and a group of residents then gathered 18,406 signatures opposing the tunnel, which is planned to carry traffic beneath a stretch of the Danube and connect two busy districts.
The city used electronic counters at nine entrances and said the final figure exceeded its previous record for a public meeting by more than 40 times. The assembly ran for six hours, with speakers given two minutes each and written submissions accepted at 24 tables. Linz has about 214,000 residents; organisers said visitors from across Upper Austria also travelled in.
“I thought I had found a dusty rule for a history lesson. I never imagined the whole riverbank would be listening to it,” Neri said, standing beside a stack of handwritten submissions.
The dispute centres on a tunnel the city says would ease congestion and improve freight links. Opponents say its price has climbed from €980 million in the first estimate to €1.46 billion, and want the money redirected towards housing, trams and flood protection. The city says the latest figure includes construction, financing and a contingency reserve.
A vote under pressure
Deputy mayor Clara Iancu told the crowd the council would publish a written response to the hearing within 60 days, as required by the old rule. She said the gathering did not amount to a referendum and could not automatically cancel contracts or planning approvals. “We have to listen, but we also have to explain what the city can legally change,” Iancu said.
The tunnel plan has divided Linz’s council for months, with supporters warning that freight traffic will keep growing and opponents calling the cost too high for a single road link. City transport director Roger Lalonde said construction had not begun and the council could still revise the project before its final financing decision.
Local historian Ísafold Kárs said she had found no record of the clause being used since the 1930s. The procedure survived later charter changes because it was never expressly repealed, according to the city’s legal review. Residents at Sunday’s meeting passed a non-binding motion calling for an independent cost comparison and a pause in procurement.
The council is due to debate the motion on Thursday. Its vote will not decide the tunnel’s fate, but the scale of Sunday’s turnout has put the project at the centre of Linz’s next budget fight — and made a forgotten paragraph in a second-hand book impossible for city officials to ignore.
