Overall layout
Baishi Bridge is composed of main bridge, bridge tower, suspension cable, sling, approach bridge and ramp, and the main bridge section is arranged in the southwest to northeast direction

Design concept
The main tower and bridgehead of the white Stone Bridge adopt European architectural style and are designed in Gothic style
[2]
, from
Archway of Dasanba, Macau
Abstract and process the elements of European Gothic architectural style such as spire, arch and beam column to conceive the shape design of the main tower
[12]
. The section of the tower column is rectangular with a number of convex columns, and the design of the steel structure on the upper part of the tower column cleverly covers the saddle, which not only creates its own landscape but also realizes the functional needs
Renaissance
The construction method inherited by the building also contains modern style, which combines with the modern cultural atmosphere of Zhuhai to produce a new European architectural style

Design feature
Baishi Bridge is the first self-anchored suspension bridge in Zhuhai. The main tower adopts "H" frame concrete structure, designed as double-tower superimposed beam self-anchored suspension bridge, and the approach bridge structure is prestressed concrete continuous box girder of equal height
[13]
. The upper and lower beams and decorative arch rings are arranged between the tower columns, and the four corners of the outer surface of the upper tower columns are provided with landscape decorative columns and the top saddle. The lower tower column is a solid round end section, the upper tower column is a solid rectangle and a decorative arc section is set at the four corners, the upper and lower beams are a single box and single room section, and the decorative arch ring is a solid rectangular section. Among them, the lower beam is a prestressed concrete structure, the top saddle is a steel structure, and the rest is an ordinary reinforced concrete structure

Technical difficulty
The difficulties faced by the White Stone Bridge and the construction technology and characteristics adopted are as follows:
1, the white stone bridge is built in accordance with the landmark bridge standard, not only the appearance of fashion, but also the technical content is relatively high, and the cable is complex to go through a lot of calculations
[2]
.
2. In the construction process of Baishi Bridge, the construction site is small, the traffic organization is difficult, the construction area is complicated, the construction coordination is difficult and other difficulties
[14]
.
3. In the design of the main tower structure of Baishi Bridge, the concept of mechanics directly guides the design direction, quickly stabilizes the structure size of the main tower and improves efficiency. Except for the main tower of suspension bridge, the method is also applicable to the compression structures with fuzzy boundary conditions such as cable-stayed bridge and pier.
4. Set the saddle cushion stone at the top of the tower, and use the space to reduce the cable saddle volume. The weight of the saddle is reduced by 51%, which directly saves the project cost; At the same time, it reduces the difficulty of cable saddle factory manufacturing, shipping and transportation, on-site installation and other links. Compared with the traditional method, this method has outstanding advantages and is universal to the design of the connection between the top of the suspension bridge tower and the cable saddle

The Baishi Bridge is of great help to alleviate the congestion of Qianshan Bridge and divert the existing traffic pressure. As a quick channel connecting Gongbei area and Nanwan area, connecting the two separate coastal areas into one is conducive to promoting the economic development of Gongbei and Nanwan and even the western district, and integrating the economic center of Zhuhai
[2]
.
(Review by Southern Metropolis Daily)
The completion of the Baishi Bridge can not only relieve the traffic pressure of the existing Bridges across the Qianshan River in Zhuhai, but also accelerate the construction of the regional road network, regional economic integration, promote the construction of Zhuhai as a "core city on the west bank of the Pearl River Estuary", strengthen the connection of regional groups, and accelerate the economic development of the western region

(Comment on the First Design Institute of China Railway Bridge Survey and Design Institute Group Co., LTD.)
The White Stone Bridge is an important project to shape the image of the city and improve the quality of the city. It connects the central city of Wanchai and Nanping, Zhuhai, and becomes an important new channel across Qianshan River, effectively realizing the seamless connection between the two sides of Qianshan River. The completion of the Baishi Bridge can effectively relieve the increasingly saturated traffic pressure of Zhuhai Qianshan Bridge and Changsheng Bridge, which is of great practical significance to further improve the traffic condition of Zhuhai and speed up the economic development of Zhuhai
