Core Points - The Hudu Creek Minjiang River Grand Bridge is located in Qingshen County, Meishan City, and is expected to be completed and open to traffic by October 2026, significantly reducing travel time from approximately 115 minutes to about 40 minutes between Qingshen County and Tianfu New Area [3][4] - The bridge employs a steel-concrete composite cable-stayed structure, marking a first in Sichuan, and has transitioned to an "industrial manufacturing and assembly construction" model, enhancing construction efficiency by 30% compared to traditional methods [4][5] Construction Efficiency - The new technology allows 80% of the bridge tower's work to be completed in a manufacturing facility, requiring only 10 workers on-site for high-altitude assembly, which can complete a standard segment in just 7 days [4][5] - The project utilizes advanced manufacturing techniques such as laser cutting and welding, achieving a manufacturing precision error of no more than 2 millimeters [5] Environmental Considerations - The bridge is located in an ecologically sensitive area near the "Tianfu Granary," necessitating a balance between construction and ecological protection [4] - The innovative construction method reduces on-site concrete pouring by over 11,000 cubic meters and improves load-bearing performance by nearly 50%, while also decreasing construction dust, noise, and wastewater emissions by over 80% [4] Project Overview - The Tianmei Le Expressway, which the bridge is a key part of, spans 94.496 kilometers and is designed to accommodate a dual eight-lane and six-lane highway standard with a speed limit of 120 km/h [5] - The total estimated investment for the project is 29.074 billion yuan, with a total construction period of 4 years, expected to connect multiple major highways and alleviate traffic pressure in the region [5]

Core Points - The Changtai Yangtze River Bridge, the world's largest span cable-stayed bridge, is nearing completion with expected operational status by August, significantly reducing travel time between Changzhou and Taizhou from 1 hour and 20 minutes to approximately 20 minutes, thus promoting coordinated development of cross-river urban clusters [2][3] Group 1: Construction Innovations - The bridge's construction has involved innovative techniques, such as the use of intelligent soil excavation robots, which have increased efficiency from 40 cubic meters per hour with six workers to 200 cubic meters per hour with one operator, allowing for a two-month acceleration in the sinking of the main tower's foundation [4][5] - The construction of the main tower has utilized a new flexible manufacturing production line for rebar, achieving automated production and mechanical shaping, with a production efficiency of eight units per hour and millimeter-level precision [5][6] Group 2: Advanced Materials and Techniques - The asphalt paving for the bridge has employed eight different paving structures and systems to address challenges posed by its large span and asymmetric loads, utilizing domestically produced materials to reduce reliance on imports [6] - The total area of asphalt paving on the bridge's upper and lower steel deck exceeds 250,000 square meters, completed in just 24 effective working days, equivalent to over 30 standard football fields [6]
