Record-breaking bridges: How Italy and China are pushing engineering limits
Italy greenlit a $15.5 billion project to build what would become the world's longest suspension bridge, infrastructure company WeBuild said on Wednesday. Over the weekend, the Chinese state-run People's Daily reported the near-completion of what will be the world's tallest bridge.
The Italian project, connecting Sicily to mainland Italy across the Strait of Messina, would stretch nearly 2.3 miles, with its suspended span reaching nearly 2.1 miles. This would surpass the current record holder, Turkey's Canakkale Bridge, by more than half a mile.
"Today, Italy has shown once again how it can come together around a mega project that will be transformative for the whole country," Pietro Salini, chief executive of WeBuild, said in a press release.
Meanwhile, in China's southwestern Guizhou Province, the Huajiang Grand Canyon Bridge reached a milestone with the installation of its final steel girder. According to Chinese state television, the bridge will stand at 2,051 feet from deck to river -- roughly twice the height of the Eiffel Tower.
Italy's bridge, designed to carry 6,000 cars per hour and 200 trains daily, focuses on connecting a major island to the mainland. China's Huajiang bridge, while completing a crucial expressway link, incorporates ambitious tourist attractions, including what will be the world's highest bungee jump.
Both projects face unique challenges, according to the Associated Press. Italy's bridge must contend with seismic risks in the Messina fault region, while China's bridge tackles the extreme engineering demands of spanning one of the world's deepest canyons, the newsgathering service noted.
The competition reflects a broader trend in global infrastructure development. While Italy aims to strengthen its connection to Sicily and bolster NATO's capabilities, China has been systematically building the world's highest bridges.
China's Guizhou Province alone has more high bridges than all other countries combined, according to HighestBridges.com.
The Italian Transport Ministry announced construction on the Messina bridge is expected to begin next year. According to People's Daily China, the Huajiang bridge is now over 98% complete, and is set to open by the end of September in southwest China's Guizhou Province.

As a tourism boom brings traffic and trash, Rockaway looks to ease the summer strain
Rockaway Beach is seeing a surge in visitors, but some locals are questioning how much their infrastructure can handle. According to the New York City Economic Development Corporation, Rockaway Beach saw 1.7 million visitors last year, up 8% from 2023, adding 300 seasonal jobs in leisure-related sectors and generating tens of millions of dollars for the local economy. "People coming from the city, we welcome them to come to enjoy our beaches, enjoy our vendors. We have small businesses, and a lot of us really wait for this summer season for our livelihood. We depend on it," Community Board 14 district manager Felicia Johnson said. For boardwalk vendor Tyrone Frison, the appeal of the Rockaways is undeniable. "Best beach in New York City," he said. "It's 'cause it's an energy, and we got love for each other." He loves seeing new faces, and these days, he says, there are many. He's not the only one who has noticed a surge in tourism. "We're excited that Rockaway is getting all of this increased attention," Jamaica Bay-Rockaway Parks Conservancy director of education Delilah McBride said. But the boom also comes at a cost — more visitors bring more cars and more trash. "The term I learned once I started this job is 'DFD': 'down for the day,'" Johnson said. While the DFD crowds may mean no harm, she says, their presence adds pressure to the peninsula's already limited resources. "Traffic is just crazy. You never move your car on the weekend," Community Board 14 chair Dolores Orr said. "People want to park legally, but when they pack the whole family, and they're riding around for a half hour trying to find a spot, they're going to park where they can." And due to new construction, Johnson says, the strain has become a year-round issue stretching well beyond the boardwalk. "People just want to develop, develop, develop," she said. "What are you giving us with the development? Infrastructure is a big issue." The community board wants to see more visitors make use of public transit. Meanwhile, they're seeking parking solutions for the local community, including converting existing lots for public use. "We have a lot of empty vacant lots here that belong to the city," Johnson said. "The city would still be making money by making it a municipal lot that people would have to pay." As for the added garbage that comes with crowds, Council Member Selvena Brooks-Powers says keeping Rockaway clean will take a multi-pronged approach. "When you walk the streets in your community, if you feel it's dirty, you don't feel safe," she said. She says she is putting discretionary funds toward sanitation and procuring cameras to catch illegal dumping while pushing City Hall for more long-term investment. The NYC Parks Department told CBS News New York that clean-up crews are working extra hours this summer to maintain restrooms, beach areas, boardwalks and playgrounds. The department says the addition of 14 new second-shift staff members working 12-8:30 p.m. has been crucial for keeping the beach trash-free throughout the busy season. Jamaica Bay-Rockaway Parks Conservancy is lending an extra hand. The conservancy welcomes volunteers at Rockaway Refresh clean-ups on Mondays to tackle weekend garbage overflow. "Have I seen trash, more debris this year than last year? Personally, I don't think so," McBride said. She says the conservancy and other groups have picked up their efforts to meet demand. "Every year, with this increased visitation, I think there's also an increase in awareness that we need to maintain these spaces, keep them beautiful and pristine," she said. "It's a good thing."
