ITALY is set to achieve a historic engineering feat with plans for the world’s longest suspension bridge – a dream that has lingered for over 2,000 years.
The ambitious project plans to connect Sicily to mainland Italy by the early 2030s, with construction sites expected to open by the end of this year.

Once finished, the bridge will stretch 3.6 kilometres (2.2 miles), surpassing Turkey’s Çanakkale Bridge as the world’s longest single-span suspension bridge.
The total cost of the mega project is estimated at an eye watering £12billion (€13.5 billion), with the European Union agreeing to fund 50 per cent of the executive design costs for rail infrastructure — around £20million.
The Italian government has vowed to manage costs carefully, including a safeguard clause that allows the cancellation of works if expenses exceed forecasts by 50 per cent.
The idea of linking Sicily to the Italian mainland dates back to ancient Rome, when Consul Metellus supposedly connected barrels and boats to transport war elephants across the strait in 252 BCE.
Since then, various attempts have been proposed but stalled, including recent efforts in 2009, which were abandoned in 2013.
Now, under the leadership of Italy’s right-wing government and Infrastructure Minister Matteo Salvini, the plan is back on track.
“The bridge will bring work, wealth, beauty, and will save tons of CO2 in the air, making it one of the greenest bridges in the world,” Salvini said.
The government has also emphasized the bridge’s potential to reduce Mafia influence in the region by creating jobs and economic opportunities.
But the Strait of Messina — linking the Ionian and Tyrrhenian Seas — poses significant engineering and environmental challenges.
Known for its strong currents and seismic activity, the area was the site of a devastating 7.1 magnitude earthquake in 1908, which killed over 100,000 people.
Despite this, the proposed design claims to withstand earthquakes up to 7.5 magnitude and winds of 300 km/h (186 mph).
The bridge will feature three vehicle lanes in each direction, as well as railway lines to boost transport efficiency.
Officials estimate the project will create over 100,000 jobs and significantly ease congestion on the region’s busy ferry systems.

Cargo arriving in Sicily could also be transferred directly to trains, potentially speeding up trade routes between southern Italy and northern Europe.
While the road to Sicily remains a symbolic bridge for now, the current government insists this project will lay “the first stone” in turning a Roman dream into reality.
“The transshipment of ferries costs more each year than building the bridge,” Salvini claims, pointing to the long-term economic benefits.
If construction proceeds as planned, the Strait of Messina bridge could be operational by 2032, transforming connectivity and realising a vision that has endured through centuries of dreams and delays.
What are the world’s longest suspension bridges?
AS of December 2024, the five longest suspension bridges in the world, ranked by the length of their main spans, are:
- 1915 Çanakkale Bridge, Turkey: With a main span of 2,023 meters (6,637 feet), this bridge crosses the Dardanelles Strait, connecting Europe and Asia. It opened to traffic in March 2022.
- Akashi Kaikyo Bridge, Japan: Also known as the Pearl Bridge, it has a main span of 1,991 meters (6,532 feet) and connects Kobe on the mainland to Awaji Island. It held the record for the longest suspension bridge from its opening in 1998 until 2022.
- Yangsigang Yangtze River Bridge, China: Located in Wuhan, this bridge features a main span of 1,700 meters (5,577 feet) and is notable for having the world’s longest double-deck bridge span. It opened in October 2019.
- Xihoumen Bridge, China: With a main span of 1,650 meters (5,413 feet), this bridge connects Jintang and Cezi islands in Zhejiang Province. It opened to traffic in 2009.
- Great Belt Bridge (East Bridge), Denmark: Spanning 1,624 meters (5,328 feet), this bridge connects the islands of Zealand and Funen. It was completed in 1998.
