A bird's -eye view of Nanyue land, the integrated three -dimensional transportation network of cross -crossed crossing. The Pearl River Estuary of the Guangdong -Hong Kong -Macao Greater Bay Area is accelerating the interconnection of the Shenzhen -Middle Channel and the Huangmao Sea Channel with other cross -sea and cross -river channels, building the "one -hour life circle" in the Greater Bay Area, and promoting Guangdong to develop in high -quality development. The wave of sailing is far away.

The "spine beam" cable stock of the Lingshengyang Bridge is more than half

The construction of the Guangdong -Hong Kong -Macao Greater Bay Area Super Engineering Shenzhen Channel Construction Jianjiabao.

On July 25, the main cable stock racks on the left and right of the Lingyuyang Bridge of the Shenzhen -Middle Channel exceeded 100, and the overall settle was half.

The main cable is known as the "spine" of the suspension bridge. The Lingshengyang Bridge single -rooted main cable consists of 199 long cable stocks. Each cable shares consist of domestic high -strength wires independently developed by 2060 MPa. It is currently the highest -level suspension bridge main cable steel wire in China.

In July, the two sides of the Shenzhen -Middle Channel and the east and west sides of the Shenzhen -Middle Channel were "two -pronged". During the same construction window, the two "Big Mac" pipe sections of the sinking tunnel were rooted smoothly. At this point, the world's widest underwater sinking tunnel, the deep -middle channel, has a total of 28 pipe sections, and the installation progress exceeds 86%.

It is also in the past 30 days, across the East Channel of the Pearl River Estuary, and the Zhongshan Bridge in the Shenzhen -Middle Channel officially co -forms the dragon. The bridge stands like a huge "harp" to stand in the river. The development of the "Golden Inner Bay" of the Guangdong -Hong Kong -Macao Greater Bay Area and the Huanzhu River Estuary.

The Shenzhen -Middle Channel of the Guangdong -Hong Kong -Macao Greater Bay Area Super Engineering is a world -class cross -sea cluster project that integrates "bridge, islands, tunnels, and underwater interoperability", with a total length of 24 kilometers. After the deep channel is opened to traffic, the drive from Shenzhen to Zhongshan will be shortened from two hours to 20 minutes.

At present, the Shenzhen -Middle Channel island tunnel project and bridge project are two -line. In terms of artificial islands, East Artificial Island is fully transferred to the construction of the tunnel structure on the island, and the construction of the ramp tunnel on the island is under the construction of the west artificial island. In terms of bridge engineering, the Zhongshan Bridge has been in the dragons and is under construction. The project is planned to be opened to traffic in 2024.

The Pearl River Estuary East and West Cross -River cross -sea channels leaps leap in the sky

Nowadays, the infrastructure of the Greater Bay Area is accelerating the interconnection, and the comprehensive three -dimensional transportation network is more and more dense, and the three places are faster. The "one -hour life circle" in the Greater Bay Area is basically formed.

On both sides of the Pearl River Estuary, the cross -river channels cross the river and cross the sea. From north to south, there are 4 cross -river channels that have been built in the Pearl River Estuary, from north to south: Huangpu Bridge, Nansha Bridge, Humen Bridge, and Hong Kong -Zhuhai -Macao Bridge. There are 7 other channels for construction and planning, namely: deep channels under construction, the cross -sea channel of Huangmao Sea, the Lion Ocean Channel, the Zhujiangkou Tunnel of the Shenjiang Railway, the Hengqin Line of Macau The Pearl Council and Lotus Mountain Crossing Crossing Crossing Crossing Crossing Crossing Crossing the Crossing Channel has become the bridge of coordinated development and aggregation of the three major metropolises in Guangzhou, Shenzhen, and Pearl River on the west coast of Guangzhou.

At present, the five main towers of the two main bridges of the Huangmaohai Bridge and Gaosu Port Bridge of Huangmao Sea Cross -Sea Channel are "rising". It is expected that the five main towers in the middle of next year can all be capped. More than 90 % of the entire pile foundation of the entire project was completed, and the goal of being opened to traffic in 2024 was further.

The Lion Ocean Channel is another Pearl River Estuary Cross Crossing Channel for the Planning and Construction of Guangdong in the "Development Planning of the Guangdong -Hong Kong -Macao Greater Bay Area".

The Lion Ocean Channel is also the first double -layer crossing channel at the Pearl River Estuary. After completion, it will become the world's largest double -layer suspension bridge. At present, the preliminary design of the main bridge of the Lion Ocean Channel passed the review and was transferred to the construction drawing design stage.

Comment

Greater Bay Area Quick Transportation Network Basically formed

"Next, it will accelerate the construction of the river crossing channels such as the Shenzhen -Middle Channel and the Lion Ocean Channel, and the extension of the large section of the traffic to enhance the traffic capacity." The mileage of traffic is more than 4,500 kilometers, and the fast transportation network is basically formed, which has effectively promoted the interconnection of people flow, logistics, capital flow and information flow. Accelerating the construction of transportation infrastructure will further support the development of the Bay Area. At the same time, with the help of smart roads and digital highways, it will build a highway operation and service system that supports the one -hour living circle in the Greater Bay Area.
