Residents are opposed to the bridge over its scale, earthquake threats, environmental effect, and mafia interference.
Thousands of people have marched in Sicily to protest against a government plan to build a bridge that would connect the Italian mainland to the Mediterranean island, and would be the world’s longest single-span bridge.
Some 10,000 demonstrators marched in the Sicilian city of Messina on Saturday to stage their opposition to the 13.5-billion-euro ($15.7bn) infrastructure project.
Residents are against the proposed Strait of Messina Bridge project over its scale, earthquake threats, environmental effect, and potential mafia interference.
The idea to build the bridge has been debated for decades. This week, however, it saw a major step forward when a government committee overseeing strategic public investments approved the plan.
Transport Minister Matteo Salvini called it “the biggest infrastructure project in the West”.
Salvini cited studies estimating the project would create up to 120,000 jobs annually and help stimulate economic growth in lagging southern Italy, as billions more are invested in surrounding road and infrastructure improvements.
Critics, however, are not convinced, and angered that about 500 families would have to be expropriated for the bridge to be built. Salvini says such families will be compensated.
“The Strait of Messina can’t be touched,” protesters shouted as they marched in Messina. Many carried banners that said “No Ponte” (No Bridge).

“They could offer me three times the value of my house, but that doesn’t matter to me. What matters is the landscape. They must not touch the Strait of Messina,” Mariolina De Francesco, a 75-year-old resident of Messina whose house lies near the site of one of the bridge’s planned 399-metre- (440-yard-)tall land towers, told The Associated Press news agency.
“Our lawyers will take action, and we will stop them. That’s guaranteed.”
The proposed bridge would span nearly 3.7km (2.3 miles) with a suspended section of 3.3km (more than 2 miles). It would surpass Turkiye’s Canakkale Bridge by 1,277 metres (1,400 yards) to become the longest suspension bridge in the world.
Preliminary work could begin in late September or early October, pending approval from Italy’s Court of Audit. Full construction is scheduled to begin in 2026, with completion planned between 2032 and 2033.
The bridge would reduce the time to cross the strait by ferry, usually up to 100 minutes, to 10 minutes by car. Trains would save 2.5 hours in transit time, Salvini said.
The project could also support Italy’s commitment to raise defence spending to 5 percent of gross domestic product (GDP) targeted by NATO, as the government has indicated it would classify the bridge as defence-related. Italy argues that the bridge would form a strategic corridor for rapid troop movements and equipment deployment, qualifying it as “security-enhancing infrastructure”.
Environmental groups, however, have lodged complaints with the European Union, citing concerns that the project would affect migratory birds.
Italy’s president has also insisted that the project remain subject to anti-mafia legislation that applies to all large-scale infrastructure projects.
