Project overview
Dashan expressway starts from Luojiang, Dazhou City, passes through Xuanhan County (Puguang, Huangjin, Changxi, Xinhua and other towns) and Wanyuan City (iron mine, Shitang, Baisha, Chaya, Guandu, Lishu and other towns), and enters Shaanxi Province through Dabashan Tunnel. Among them, Daba Mountain Tunnel is 6170m long, Dashan expressway Sichuan is138.58km long and Wanyuan is 58km long, with an estimated total investment of 8,386.77 million yuan. Wanyuan Iron Mine, Baisha, Chaya and Guandu interchanges have been opened.
This road will be opened to traffic during the Eleventh Five-Year Plan period. At that time, it was only 350 kilometers from Wanyuan to Xi and it took three hours to drive. 3 15km south to Chongqing, 3 hours' drive. It is 560 kilometers west of Chengdu, and it takes 5 hours by car. Wanyuan city will truly become the hub of Sichuan-Shaanxi traffic line.
On February 25th, 2007, at 65438+, the construction of Da (Zhou) Shaanxi (West) expressway, a large passage from Sichuan to Shaanxi, started.
Sprint construction
The 5 1% section of Dashan Expressway is full of bridges and tunnels, and only the slope protection and toll station construction have not been completed.
Along the way, there are provincial scenic spots such as Batai Mountain and Longtan River, and you can see many unique landscapes such as the sea of clouds and waterfalls in Emei, East Sichuan.
The 5 1% section of Dashan Expressway is full of bridges and tunnels. The Daba Mountain Tunnel at the junction of Sichuan and Shaanxi is more than 6 kilometers long, and it enters Shaanxi through the tunnel ... Recently, the reporter of Huaxi Daily walked into expressway, a mountain that is about to be completed, and enjoyed the scenery along the expressway in advance. At present, only the slope protection and toll station construction of the whole Dashan expressway has not been completed, and it is expected to be officially opened to traffic in the middle of this month. By then, Chengdu-Dazhou-Ankang -Xi 'an will realize the whole line of expressway. Besides Guangshan Expressway, Dashan Expressway is the second new northward passage in our province.
Dashan expressway starts from the north of Dazhou, passes through Xuanhan, Puguang, Baisha and Wanyuan, and ends at the junction of Sichuan and Shaanxi in Dabashan Tunnel, with a total length of 143.244 km.
At present, the 33-kilometer line from Dazhou to Puguang in Dashan expressway has been opened to traffic, and the rest sections are under closed construction. Lan Fuan, deputy general manager of Dashan expressway Company, said that the pavement construction of the unopened section has been completed, and the traffic signs on the pavement and roadside have been basically installed. There are still roadside slope protection and toll stations under construction, and the whole construction is nearing completion.
The reporter saw at Dashan Expressway that the whole line was paved with asphalt pavement, and the guardrails, traffic signs, ventilation equipment and reflective signs in the tunnel were all installed, so the car could run smoothly. In Wanyuan, workers are building roadside slope protection in many sections, and the main structure of some toll stations along the line has been completed, and post-decoration and electromechanical equipment installation are underway.
There are 9 toll stations in Xuanhan, Puguang and Huangjin, and 3 service areas in Dazhou North, Wanyuan South and Wanyuan North. These service areas are expected to be completed by the end of this year.
5 1% of the road conditions are bridges and tunnels.
The whole line of Dashan Expressway is mountainous terrain, and the 5 1% section is bridges and tunnels. From Dazhou to Puguang, the mountains on both sides are relatively gentle. In this season, the mountains are covered with golden rape flowers, and the scenery is very charming.
Driving from Puguang to Shaanxi, the number of tunnels and bridges in this section began to increase, among which the highest pier of Changxi Bridge in Xuanhan County reached 84 meters, and expressway shuttled in mid-air.
Entering Wanyuan territory, the mountains on both sides become steep, especially at the junction of Sichuan and Shaanxi. This section of the road is almost full of bridges and tunnels. One of the 6 km long tunnels will cross Daba Mountain. After the tunnel is drilled, it will enter Shaanxi and connect with Ankang, which has been opened to traffic, to expressway, Sichuan.
The scenery can be traveled to places such as Yunhai Waterfall.
The construction of Dashan Expressway makes it more convenient for people along the line to travel, and many people are looking forward to the early opening of this road.
Lei Fafei now lives in Wanyuan. He used to go to Dazhou on business. By car, he can only take the national highway 2 10, which took more than three hours. In many cases, he can only go by train. However, because there are not many trains, Lei Fafei always feels inconvenient. Now, Dashan expressway connects Dazhou, Xuanhan and Wanyuan, and it only takes him 1 more hours to go to Dazhou downtown.
"There must be many people coming here to play in the future." Lei Fafei said that Wanyuan has provincial-level scenic spots such as Batai Mountain and Longtan River, where you can see many unique landscapes such as the sea of clouds and waterfalls in Emei in eastern Sichuan, and you can also escape the summer and drift in Longtan River Scenic Area. In addition, the karst landforms and waterfalls of Bailixia in Xuanhan County are also very beautiful. After expressway is opened to traffic, citizens from Chengdu and Dazhou can drive here to play.
