[Another sea-crossing bridge in Xiamen is about to start construction] On March 22, 2023, the candidates for the survey and design of the cross-East Sea Channel Project in Xiamen have been announced, and the recommended candidates for the bid are Shanghai Municipal Engineering Design and Research Institute Co., Ltd. and Fujian Provincial Transportation Planning and Design Institute Co., Ltd. consortium. The project is located in Jimei District, Tong'an District and Xiang'an District. It starts from Haixiang Avenue, crosses the East China Sea using a public-rail bridge construction scheme, and ends at Xidong Road Airport Expressway, with a total mileage of about 20.9km. The main line of the project adopts the first-class highway and urban expressway, and the auxiliary road adopts the standard of urban trunk road. The main line of the land section has 6 lanes in two directions, the main line of the highway in the sea area has 8 lanes in both directions, and the number of main lines of the track is double; auxiliary roads: Jimei and Tong'an sections have 4 lanes in both directions, and Xiang'an section has 6 lanes in both directions. The design speed of the main line is 80km/h, the design speed of the auxiliary road is 40km/h, and no auxiliary road is set in the sea area. The main line bridge of the land section is 9,938 meters / 4, including 2 super-large bridges: the total length of the Jimei section of the super-large bridge is 2,035.5 meters; the total length of the Xiang'an section of the super-large bridge is 6,838.5 meters. The combined highway and rail bridge in the sea area is about 6.22 kilometers long. The sea-crossing bridge spans two waterways, of which the west navigation hole adopts a cable-stayed bridge with a span of (188+330+188) m; the east navigation hole adopts a steel truss girder with a span of (110+132+110) m. 110m steel truss girders are used for non-navigation holes. The connecting bridge at both ends is 1.82 kilometers long, which is basically the same type as the bridge in the land area. The tentative estimated price of the project is 19.997 billion yuan, of which construction and installation costs are about 13.575 billion yuan. Editor / Zhao E
