According to the data of CBI Construction Network, the expressway line along the coast of Zhejiang Province is about 378 kilometers long, with magnificent scenery, spanning Sanmen Bay, Taizhou Bay and Yueqing Bay, with a design speed of 100km/h and a construction period of about 4 years. This project provides a convenient and quick way to realize the "integration into the Yangtze River Delta, the construction of Hangzhou-Ningbo Wenzhou metropolitan area, the development of Wenzhou-Taiwan coastal industrial belt, and the protection and rational development of the blue barrier along the east coast of Zhejiang" proposed by the provincial party committee and the provincial government.
general situation
Expressway, a coastal city in Zhejiang Province, is also called Ningbo-Taizhou-Wenzhou high-speed double track. It is the "one company" in the main skeleton of "two vertical lines, two horizontal lines, eighteen lines, three rings and three passages" in the Outline of Highway and Waterway Traffic Construction Planning in Zhejiang Province (2003-20 10), and it crosses the Hangzhou Bay Bridge to the north through the proposed Xiangshan Port University and goes straight to Shanghai.
Expressway, a coastal city in Zhejiang Province, is composed of a main line of the double-track line of Yongtaiwen Expressway (S 19) and four branch lines, namely, Yongchuanshan Shugang Expressway (S20), Liu Heng Shugang Expressway (S2 1), Xiangshan Bay Shugang Expressway (S22) and Shipu Shugang Expressway (S23). The main line starts from Yunlong Interchange of Ningbo Ring Expressway in the north and passes through Yinzhou, Xiangshan, Ninghai, Sanmen, Linhai, Jiaojiang, Luqiao, Wenling, Yuhuan, Yueqing, Longwan, Ruian, Pingyang, Cangnan and other 14 counties (cities, districts), with a total length of about 378 kilometers.

Sanmenwan Bridge and its wiring project have passed the preliminary design site review organized by the Ministry of Transport. The project, with a total length of about 54.5 kilometers, will start construction this year and is expected to be completed and opened to traffic by the end of 20 18. After Hangzhou Bay Bridge, Zhoushan Bridge and Xiangshan Port Bridge, there will be another "flying rainbow on the sea" in our city.
According to the preliminary design, the project starts from Dai Gang, Xiangshan, and is connected with Xiangshan Port Bridge, which has been completed and opened to traffic. It passes through Maoyang, Yue Jingyang and Ninghai Long Street, passes through Sanmen Bay via Shepan Island, and ends in Liu 'ao, Sanmen County, connecting with Taizhou Bay Bridge and the wiring project under construction. Sanmenwan Bridge is about 1 1.8km long, and the wiring length on both sides is about 42.7km.. The whole line is built according to expressway standards, with a design speed of100km and an estimated total investment of129.8+0.6 billion yuan.
Prospect: After the completion of Sanmenwan Bridge, the urban area of Ningbo will be more closely connected with Xiangshan and the south of Ninghai. After connecting Xiangshan Port Bridge and its wiring, Taizhou Bay Bridge and its wiring, Yueqing Bridge and its wiring, the coastal expressway of our province (double track of Yongtaiwen Expressway) will finally take shape, and the traffic pressure of Yongtaiwen Expressway will be greatly alleviated. At the same time, the project is of great significance to strengthen the connection between coastal ports in southeastern Zhejiang and between ports and hinterland, improve the port collection and distribution capacity, optimize coastal economic industries, and promote the coordinated economic and social development along the route.
Taizhou section
Taizhou coastal expressway is located in the second section of Zhejiang coastal expressway, which runs through six counties (cities, districts) in Taizhou. It is one of the main skeletons of the "three vertical and three horizontal links" highway in Taizhou Traffic Construction Plan (2003-2020), connecting Sanmen Bay to Ningbo in the north and Yueqing Bay to Wenzhou in the south. Taizhou is a young coastal city on the Gold Coast of China, located in the central part of Zhejiang, at the southernmost tip of Shanghai Economic Zone, and a member of the "Yangtze River Delta" economic urban agglomeration. Taizhou has a land area of 94 1 1 km2, an ocean area of 80,000 km2 and a population of 5.65 million. Among them, the urban area is 1.536 square kilometers and the population is1.50 thousand. Jiaojiang, Huangyan and Luqiao districts in the urban area have jurisdiction over Linhai and Wenling, and Yuhuan, Tiantai, Xianju and Sanmen counties. In 2005, the city's GDP reached 65.438+046.748 billion yuan, the annual per capita disposable income of urban residents was 65.438+09036 yuan, and the per capita income of rural residents was 7368 yuan. The number of cars per 100 households in Taizhou is 16.67, ranking second in Zhejiang. With the arrival of Hangzhou Bay Bridge and the rapid construction of Ningbo-Taizhou-Wenzhou coastal industrial belt, the traffic task in Taizhou is getting heavier and heavier, and the high-speed traffic volume in Taizhou section of Ningbo-Taizhou-Wenzhou is about to be saturated, so it is imperative to speed up the construction of coastal expressway.
With the great attention of the Zhejiang Provincial Party Committee and the provincial government and the support of relevant provincial departments, the preliminary work of coastal expressway has been promoted in an orderly manner. Relevant state ministries and commissions have agreed in principle to divide the whole project into four sections for approval: Yunlong to Xiangshan Wall, Xiangshan Wall to Yueqing Nantang, Yueqing Nantang to Ruian Feiyun and Ruian Pavilion Lane to Cangnan Horse Station. The first paragraph of Yunlong-Xiangshan wall project proposal has been approved by the state, and the "work permit" has been reviewed. It is being reported to the National Development and Reform Commission and the Ministry of Communications for approval, and the project has entered the preliminary design stage; The second bid section of "Work Permit" from Xiangshan Qiangtou to Yueqing Nantang has passed the preliminary examination of the Provincial Development and Reform Commission and the Communications Department, and the text of the work permit and the special report of 17 will be completed soon; The "pre-permit" of the third bid section from Nantang to Ruian Pavilion Lane in Yueqing has been reviewed and the text of "work permit" is being compiled; The fourth bid section, from Ruian Tingxiang to Cangnan Mazhan Station, has completed the line position demonstration report and is connecting with the planning of expressway network in Fujian Province. This project belongs to the second stage, and the preliminary work is carried out intensively and orderly. Zhejiang Transportation Planning and Design Institute further designed the scheme optimization, and determined the line position optimization scheme on March 15. In order to speed up the preliminary work of the project, Taizhou City established the coastal expressway project construction headquarters of Taizhou City and counties (cities, districts) in early 2006, and equipped with professional departments and personnel to carry out the preparatory work.

Yueqing Bay Bridge will span Mao Cong Island.
Yueqing Bay Bridge and its wiring works are located at the southernmost tip of the three projects. The route starts from the south of Wenling in the north and ends at Nantang in Yueqing, Wenzhou in the south, with a total length of 38.438+09 kilometers. The whole line mainly passes through Wenling South, Yuhuan Shamen, Longxi, Lupu Yucheng, Haishan (Mao Cong Island) and Nantang Town, Yueqing, Wenzhou, with a total investment of 654.38+0.2 billion yuan.
There are four interchanges in this project. Where should the citizens of Wenling and Yuhuan go to the coastal expressway? It is understood that Wenling citizens can take the expressway from Shamen Interchange, and Yuhuan citizens can take the expressway from Yuhuan Interchange, Lupu Interchange (also a parking area) and Haishan Interchange. If you go south to the Nantang Hub in Yueqing, Wenzhou, you can get on the Yongtaiwen Expressway.
It is understood that the cross-sea bridge of Yueqing Bay Bridge is mainly composed of Yueqing Bay Bridge 1 and Yueqing Bay Second Bridge. Among them, the Yueqing Bay Bridge 1, which will be started at the end of the year, starts from Fenshui Mountain in Lupu Township, Yuhuan, connects the Damaiyu Shugang Separation Viaduct and ends at the east bank of Mao Cong Island, with a total length of 4,000m.

The total length of the bridge is 3230 meters, the main bridge is 685 meters and the main span is 365 meters. The cable-stayed bridge with twin towers and double cable planes is a rhombic tower with auxiliary piers on its side span. The navigable span bridge of Bridge 1 can pass 5000-ton seagoing ships (representing ship-type general cargo ships).
Taizhou Bay Cross-sea Bridge is navigable to 10,000-ton seagoing ships.
Taizhou Bay Bridge and its wiring project start at Lianxintang, Liu Ao Town, Sanmen County and end at Shatoumen, Chengnan Town, Wenling City.
The whole line passes through Sanmen Snake Plate, Liu Ao, Jiantiao, Lipu, Xiao Xiong and Lin Si; Linhai Tao Zhu, Shangpan and Du Qiao; Jiaojiang Qiansuo, Sanjia and Jiaojiang Farm; Luqiao Peng Street and Jinqing; Wenling Binhai, Ruoheng, Shiqiaotou and Chengnan, with a total length of 102.366 km. It is understood that Taizhou Bay Bridge and its wiring project have a 1 hub, 9 interchanges and 2 service areas, with a total investment of 24 billion yuan. The hub is located in Jiaobei, from which you can enter Jintai expressway.
These nine interchanges are located in Liu Ao and Lipu of Sanmen; Tao Zhu and Du Qiao are at the seaside; Jiaojiang Shugang Avenue; Luqiao jinqing town and pengjie town junction; The coastal and ruoheng areas south of Wenling. In other words, local citizens can get on the Taizhou coastal expressway from these places.
Taizhou Bay Bridge and its wiring project have two service areas, which are located in Tao Zhu, which is near the sea, and Shiqiaotou Town, Wenling City.
Let's talk about Taizhou Bay Bridge.

The total length of Taizhou Bay Bridge is 4038 meters, the main bridge is 948 meters and the main span is 488 meters. The water area of the bridge site is about 3,500m wide, the river bottom is flat and shallow dish-shaped, and the water depth is 4-6m. The main channel is used for 654.38+00,000-ton seagoing ships (representing ordinary cargo ships).
Sanmen snake tray has a service area.
Sanmenwan Bridge and its wiring works mainly start from Xiangshan in Ningbo in the north and reach Sanmen Liu Ao in the south, of which Taizhou is responsible for about 6.7 kilometers. In this project, there is also a service area, located in Sanmen Snake Plate.
Wenzhou section
Wenzhou section of Yongtaiwen, expressway is an important part of the National expressway Network, the main skeleton of the provincial and municipal expressway, and the first particularly important transportation infrastructure project in Wenzhou in the first year of the Twelfth Five-Year Plan. It starts from Nantang, Yueqing, passes through Yueqing, Longwan, Ruian, Pingyang and Cangnan, and ends at Cangnanma Station, which borders Fujian. The total length is about 135.69 km, and the designed driving speed is 100 km/h. Among them, the Yueqing Nantang Hub-Yueqing Interchange and Shenhai (Yongtaiwen) expressway * * line are widened to 8 lanes by using the old road. The estimated total investment of the project is about 34.574 billion yuan, and the planned construction period is 4 years (excluding the Oujiang Beikou Bridge section).
Wenzhou section of Ningbo-Taizhou-Wenzhou double-track expressway will connect Wenzhou airport, deep-water seaport and other major infrastructure, and run through the eastern coastal areas with the best industrial base and the strongest economic vitality in Wenzhou, which plays a key role in improving the comprehensive transportation efficiency of coastal land transportation, expanding the economic hinterland of Wenzhou port and accelerating the development of marine economy. It will also undertake the northern line of the ring expressway on the north bank of Oujiang River and the southwest line of the ring expressway on the south bank of Feiyun River to form a closed loop of Wenzhou and expressway, which is of great strategic significance for Wenzhou to open the framework of "1650" metropolitan area, enhance the radiation and driving force of the central city, better "connect with Haixi District and integrate into the Yangtze River Delta" and build a national transportation hub city.
It is understood that in the next five years, Wenzhou will focus on building modern transportation, weaving "1650" urban rapid transportation network, building a national transportation hub, improving Wenzhou's internal transportation environment and improving its external transportation level. During the "Twelfth Five-Year Plan" period, Wenzhou plans to invest 654.38+05 billion yuan to build transportation infrastructure such as expressway, ports, airports and national and provincial highways, and will invest huge sums of money to build regional railways and urban public transportation. Among them, the investment in highway transportation will exceed 1000 billion yuan, which is six times of the "Eleventh Five-Year Plan" and accounts for about one-third of the total highway investment in the province.
It will become the widest expressway in our city.
The main line of Wenzhou section of Yongtaiwen Expressway is about135km long. Nantang-Huanghua section and Hannah Quinlivan-Gexiang section are important parts of Wenzhou section, with a total length of about 78 kilometers. It is 23.65km from Nantang to Yueqing Hub, which is widened from the existing four-lane expressway in Ningbo-Taizhou-Wenzhou (Shenhai) to eight lanes. The remaining new sections are two-way and six-lane. When completed, this section of expressway will be expressway with the most lanes in our city.
The reason why Wenzhou section of the double-track line of Yong-Tai-Wen Expressway is not completely widened on the basis of the old road, but a new road is rebuilt on the sea side is mainly to expand the urban framework, make more towns and villages enter the coverage area of expressway, and provide more convenient transportation and travel services for these areas; At the same time, coastal ports, industrial bases and urban functional areas also need strong traffic arteries to support their development; In addition, houses and factories along the old road are dense, and a large amount of demolition is also under consideration.
The continuous viaduct is the longest in China.
The reporter learned from the meeting that in order to save land resources, viaducts were widely used in the preliminary design of the project. In the 78km mileage from Nantang in Yueqing to Ruian Pavilion Lane, the continuous viaduct extends from Huanghua Hub in Yueqing to Ruian Pavilion Lane (including Oujiang Bridge), with a total length of 46km, which will become the longest highway bridge in China, which is10km longer than Hangzhou Bay Bridge. According to the relevant person of the construction unit, on the one hand, the construction of viaduct can save the area of subgrade, on the other hand, the space under the bridge can be used as municipal road. In the long run, the comprehensive cost of building viaduct is more cost-effective than building subgrade highway.
The truck and the bus parted ways.
Wenzhou section of Yongtaiwen (Shenhai) in expressway is one-way and two-lane, and bus drivers often encounter depressed things: two heavy trucks are driving side by side at low speed, occupying the main lane and overtaking lane, and the cars coming from behind can only drive slowly behind their buttocks.
This situation will be avoided by Yong-Tai-Wen high-speed double track. According to reports, the Wenzhou section of the double-track line of Yongtaiwen Expressway connects several ports. In the future, large trucks will pass through this road intensively. At the same time, it connects Wenzhou airport with several economically strong towns in our city, and buses will often pass by. In order to reduce the mutual interference between passenger cars and trucks, expressway design adopts three separate ways: truck, passenger car and overtaking. Freight cars go their own way, which can reduce the obstacles to passenger cars.
