Important influence
After the completion of the Bay Bridge, the communication between Jinan and Qingdao in the province will be closer and more convenient. In the past, vehicles had to bypass the Jiaozhou Bay Expressway and go to Huangdao along the south line of Qing Ji Expressway. Since the northern starting point of Qing Ji South Line is connected with the Bay Bridge under construction, after the completion of the bridge, vehicles can go directly to Qingdao along Qing Ji South Line and Bay Bridge. The bridge will further promote the traffic links between Qingdao and the cities in the peninsula urban agglomeration, which is of great significance to give play to Qingdao's leading position in the economic development of Shandong Province, further accelerate the construction of the Shandong Peninsula urban agglomeration and promote the tourism development of Jiaodong Peninsula.
For Qingdao, the Bay Bridge is also an important transportation hub in the city's strategy of "protection and development around the bay". After the completion of the bridge, the traffic pressure of Qingdao Jiaozhou Bay Expressway will be greatly relieved, the east-west cross-sea traffic connection of Qingdao will be further improved, the urban skeleton of Qingdao will be expanded, the time and space distance between Qingdao and Hongdao and Huangdao will be shortened, the connection between the main urban area and the two wing sub-urban areas will be strengthened, and the great Qingdao urban framework embracing Jiaozhou Bay will be shaped, opening up a new space for the in-depth development of Qingdao.
The total length of the expressway around Jiaozhou Bay is about 70 kilometers. The construction of the bridge project will conveniently connect Qingdao, Hong and Huang islands, shortening the land distance from Qingdao to Huangdao by nearly 30 kilometers. If the speed is 80 kilometers per hour, taking the bridge will save 20 minutes compared with taking the expressway! The bridge has two lanes and six lanes, with a design speed of 80 kilometers per hour.
Regarding the wind-resistant and fog-proof design of the bridge, experts said that the wind-resistant performance is excellent and it was designed to resist the once-in-a-century gale. But the interference of sea fog is inevitable. To "connect" with the expressway, the whole line should be closed in heavy fog. According to meteorological statistics, the bridge is closed for about 20-30 days every year, and it is closed for about 80 days in strong wind, heavy rain and fog.
traffic
Between Qingdao and Huangdao, Jiaozhou Bay Cross-sea Tunnel and Jiaozhou Bay Bridge have been connected with the expressway around Jiaozhou Bay by ferry until they are completed and opened to traffic. Ferry is limited by transportation capacity and climatic conditions, and can only pass more than a thousand vans every day; The design standard of the expressway around Jiaozhou Bay is 25,000 standard cars/day, but the traffic volume has soared year by year after opening to traffic. At present, the peak traffic volume of standard sections has reached 460,000! The construction of this project will connect Qingdao, Hong Kong and Huangdao conveniently, which will not only shorten the land distance from Qingdao to Huangdao by 30 kilometers, but also ease the traffic pressure. At the same time, the bridge built on Hongdao can also take into account the traffic on Hongdao.
At the mouth of Licun River in the old city, the bridge connects Chongqing Road and National Highway 308 in the form of urban expressway, which directly introduces the traffic flow from the city to the outside of the city into the expressway, reducing the traffic flow collected and evacuated by multiple entrances and exits of Jiaozhou Bay Expressway in all directions in the city, effectively reducing the traffic congestion in the external communication part of the old city and improving the traffic situation in the city.
After the completion of Qingdao Bay Bridge, the business volume of Qianwan Port, Huangdao Oil Port and Xuejiadao Port can be effectively increased, so that the old port of Qingdao, the oil port and Qianwan Port can be integrated, the cooperation among the three ports can be strengthened, and the overall benefits of the ports can be better brought into play, especially the problem of land collection and transportation capacity of Qingdao Port.
industry
According to the industrial layout, the spatial scope of the east coast area centered on the old city is narrow, and there is almost no room for urban space to expand eastward. As the port moves westward, it is imperative for the economic center to move westward. The construction of Qingdao Bay Bridge organically links the three islands of "green-red-yellow" and greatly promotes the implementation of the urban development strategy of "three-point layout, first-line development and group development" in our city.
travel
In the website of Langyatai Scenic Area, the signboard "After the completion of the Bay Bridge, you can reach the urban area in 30 minutes" has already been hung. It is understood that there are not a few scenic spots like Langyatai waiting for the "benefits" brought by the Bay Bridge. After the project is completed, it will not only release the development space of tourism and tertiary industry in the east, but also connect the contiguous seaside resorts in the old city with the provincial tourist resorts in Xuejiadao, Huangdao District, which will greatly promote the development of Qingdao tourism and form an "encirclement circle" of Qingdao tourism.
Meet/suit the convenience of the local community
In the "Qingdao" online community, netizens have been discussing Qingdao Bay Bridge. One of the senior netizens commented, "Huangdao Development Zone and Qingdao are separated by Jiaozhou Bay, which can be described as' green and yellow'. Therefore, the construction of the cross-sea bridge has become a lingering complex in Qingdao for many years. It's time to wait for no one. "
The customs declaration place of export goods is in Huangdao over there, and most trading companies are in Qingdao city. When an enterprise declares taxes, it can only be paid by the customs broker. Obviously, this has brought inconvenience to their operation and financing. A private entrepreneur said, "I am looking forward to this bridge. I am already eager to see it."
