In the early morning, a thin mist shrouded the busy dock of Tieshan Port, and trucks loaded with goods lined up in long lines on Shugang Avenue. For driver Lao Li, who travels back and forth between Hepu and the port area all year round, every detour means a loss of time and cost. However, with the recent release of a bidding announcement, the bottleneck in Old Li's heart is about to change - the G228 line Tieshan Port Xianghai Bridge has officially launched a franchise bidding, and this sea route that carries countless people's expectations has finally moved from blueprint to reality.

The long rainbow across the sea falls on Jiugao

As a key link of the G228 National Highway from Dandong to Dongxing Guangxi, the Tieshangang Xianghai Bridge is not only an expansion and upgrading project of the national highway, but also a true urban expressway in Beihai City. The project is located between Tieshangang District and Hepu County in Beihai City, with a total length of 9.466 kilometers. The bridge tunnel ratio is extremely high, like a steel dragon diving into the sea.

The most striking feature is the technically complex cross sea bridge, with a total length of 4908 meters, supplemented by a 546 meter bridge and a 68 meter medium bridge. This is not just a few cold numbers, but also a physical connection for the coordinated development of the North Sea land and sea. After the completion of the project, it will completely change the history of relying on ferries or detours by land, achieve rapid direct connection between Tieshan Port Area and Hepu County, and fill the last puzzle of the Beibu Gulf Coastal Highway Network.

Six cars running parallel smoothly

Different from ordinary cross sea bridges, the Tieshangang Sea Bridge has a highly forward-looking design concept and is a truly dual-use bridge for both public and urban use. The project adopts the standard of two-way six lane first-class highway, with a design speed of 80km/h, to ensure the efficient and smooth flow of trunk logistics. At the same time, wide municipal supporting spaces have been reserved on both sides of the bridge, with a 3.25-meter-wide sidewalk and facility strip and a 3.5-meter-wide non motorized vehicle lane on one side.

This means that the main bridge section of the bridge has a total width of 50 meters, and the approach bridge has a total width of 47 meters. Whether it's speeding trucks, leisurely cyclists, or even citizens walking to watch the sea, they can all find their own right of way on this bridge. This composite cross-section design not only meets the fast pace of port collection and distribution, but also takes into account the comfort of urban slow traffic, reflecting the development wisdom of port city integration.

Billion dollar industry borrowing from the east wind

The hard connectivity of infrastructure is a prerequisite for the high-quality development of industries. The total investment of Tieshangang Xianghai Bridge is estimated to be 3.201 billion yuan, and the construction period is tentatively set at 3 years, which will be promoted through a franchise model. With the implementation of the project, the agglomeration effect of Tieshangang Port Industrial Park will be further amplified.keywords:Engineering infrastructure

The construction of the bridge will strongly support the upgrading of the industrial distribution system near Tieshan Port, reduce logistics costs, and improve customs clearance efficiency. It is like a thick blood vessel, delivering a continuous stream of economic vitality to the North Sea and even the entire Beibu Gulf Economic Zone. From improving the regional road network to promoting the optimization of industrial layout, this bridge will become an important engine to drive the development of Beihai City towards the south and the sea, helping the Beibu Gulf Economic Zone to break through the waves of opening up to the outside world.Editor/Yang Meiling
