"是友谊之桥、发展之桥，也是通向未来之桥" 回望大桥建设历程，圭亚那青年工程师加内什仍然记得许多细节。 加内什曾在特立尼达和多巴哥求学，毕业后在当地从事建筑工作。得知家乡的大桥即将开建，他回国加 入了铁建国际。从打下第一根桩，到吊装第一片梁，再到安装第一根斜拉索，加内什体验了职业生涯中 多个"第一次"。"更重要的是，我从中国同事那里学到了宝贵的技术，对我而言是全新的收获。"他 说，"我由衷感谢中国同事把先进技术带到圭亚那，感谢中国企业把这座一流的大桥带到圭亚那。" 大桥建设远非简单的技术"移植"。面对河口超深软土层、强腐蚀海洋环境、每日3米潮差等挑战，建设 团队采用创新施工技术，将120米超长桩深植地下，奠定了工程的稳固根基。项目总工程师宁广委介 绍，当地砂石细粒含量过高、进口砂成本高昂，为解决该难题，项目部研发出"束水分沙"工艺，从本地 砂中分离出符合标准的中粗砂，就地解决了砂料问题。 在圭亚那首都乔治敦西部，德梅拉拉河奔涌流向大西洋。1.8公里宽的河面上，一座钢筋混凝土斜拉桥 凌空飞架，成为城市的新地标。这是由中国铁建国际集团有限公司（以下简称"铁建国际"）承建的新德 梅拉拉河大桥（见图，胡自含摄）。圭亚 ...

Core Viewpoint - The construction of the new Demerara River Bridge in Guyana is a significant infrastructure project aimed at improving transportation and connectivity, while also integrating local cultural elements and environmental protection measures [3][4][5] Infrastructure Development - The existing Demerara River floating bridge, built in 1978, has become a bottleneck for transportation in Georgetown, causing long wait times and frequent disruptions [3] - The new bridge, designed by China Railway Construction, spans 2,900 meters and is the largest and most complex infrastructure project in Guyana [3][4] - The bridge will feature a double-tower, double-cable-stayed concrete design with a four-lane roadway, allowing for a speed limit of 80 km/h and a lifespan of 100 years [4] Environmental and Cultural Considerations - The design process incorporates local cultural elements, such as a modern abstract representation of an indigenous chief's feather crown at the top of the bridge towers, symbolizing Guyana's historical roots [4] - Environmental protection measures include minimizing the impact on mangrove ecosystems by preserving root systems and reducing deforestation during construction [4][5] Economic Impact - Upon completion, the bridge is expected to reduce travel time across the Demerara River by three-quarters and allow 50,000-ton vessels to pass freely, effectively doubling the volume of boat traffic beneath the bridge [5]

Core Insights - The upcoming elections in Guyana are expected to have significant implications for the global oil market and the United States, given the country's increasing oil production and strategic resources [1][3][5] Economic Impact - Guyana's economy has transformed since 2015, when ExxonMobil discovered approximately 11 billion barrels of oil, leading to a surge in oil production [3][4] - The country currently produces about 650,000 barrels of oil per day, with projections indicating that by 2035, production could reach approximately 2 million barrels per day, surpassing the total output of several neighboring countries [3][4] - Guyana's GDP growth rates have been remarkable, with a 63.3% increase in 2022 and a projected 33.8% growth in 2023, marking five consecutive years of double-digit growth [3][4] Political Context - The elections are crucial for the management of the newfound oil wealth, with analysts emphasizing the need for inclusive and stable governance to avoid undermining democracy [4][5] - The current president, Irfaan Ali, is seeking re-election amidst competition from notable figures, including Aubrey Norton and Azruddin Muhammad, the latter of whom is under U.S. sanctions [4][5] Territorial Disputes - Tensions with Venezuela over the Essequibo region, which is rich in oil and gas resources, have escalated, particularly following recent discoveries in the area [5][6] - Venezuela's National Assembly has approved a referendum regarding the region's sovereignty, which Guyana views as a violation of international law [6] Geopolitical Dynamics - Guyana is positioned between U.S. and Chinese economic interests, with U.S. companies leading in oil production while Chinese investments focus on infrastructure projects [8][12] - The construction of the new Demerara River Bridge, funded by China, is a significant infrastructure project that highlights China's growing influence in the region [9][11] - Analysts suggest that if Guyana can balance relations with both superpowers, it could leverage these connections for economic and political benefits [8][12]

Core Viewpoint - The successful completion of the Demerara River Bridge in Guyana, constructed by China Railway Construction International Group, marks a significant achievement in infrastructure development, enhancing connectivity in the Caribbean region [1][9].
