Changyang City passed the dragon boat ping, and the two sides of the Qingjiang River shook hands again.
On October 26th, the flying swallow-like posture of the Qingjiang Special Bridge spanned a blue wave of a river, and the rainbow bridge on the water and the reflection in the water were reflected in a painting. The bridge, which is still under construction, has become a new internet celebrity attraction in Changyang, and people often stop to take photos under the bridge.
Changyang is located in the southwest of Hubei Yunnan-Guizhou Plateau east extension tail, Wuling Mountain remnants, traffic has always been a constraint on development. In the golden autumn, our reporter came to the Changyang Qingjiang Special Bridge, Yichang Expressway, 318 National Highway (Changyang Section) reconstruction project and other project sites, and the hot construction scene is building the dream of Changyang's "big county town" and "big traffic".
The two sides of the Qingjiang River shook hands again
Changyang Longzhouping Town Guanyin Pavilion, here is the starting point of the Longping (Zhouping) Five (Eye Spring) first-class expressway, but also the north bank of the Qingjiang Special Bridge. Follow the construction road into the bridge deck, where welding flowers splash and workers are installing protective barriers. Yao Dongxu, director of the bridge construction area, told reporters that the construction of the bridge has entered the end, and then will enter the bridge deck paving.
Qingjiang Special Bridge is the largest bridge on the Long (Zhouping) Five (Eye Spring) first-class highway, and is also one of the important projects for the transportation construction of the National Wuling Mountain Ethnic Minority Economic and Social Development Pilot Zone.
"The total length of the bridge is 354.8 meters, with 4 lanes in both directions and a design speed of 60 kilometers per hour." Tian Ruifeng, director of the office of the Changyang Qingjiang Special Bridge Construction Coordination Headquarters, introduced that the bridge is a flying swallow-type steel truss pole arch bridge, with a light shape, and the scenery on both sides of the Qingjiang River is integrated.
On January 14, 2021, the main arch of the bridge was closed, and people on both sides of the Qingjiang River spontaneously came out to watch. In particular, the masses on the south bank are finally going to end the era of using "strokes" or detours into the city. Mao Dezhen, a villager in the second grid of Hejiaping Community, said: "Ancestors have suffered from crossing the river for generations, and building the bridge is for the benefit of future generations."
The Longwu Expressway has a total length of 18.2 kilometers, a design speed of 60 kilometers per hour, and four lanes in both directions. On the north bank of the Qingjiang River, Guanyin Pavilion is connected to the 324 Provincial Highway, the Shangqingjiang Special Bridge, through Moshi, will go directly to the Yidu Wuyan Spring, and connect to the Land (City) Yu (Yangguan) First-class Highway.
The reporter walked to the south bank of the bridge, and Shamao Mountain blocked the way to the bridge. "Soon there will be a tunnel through Shamao Mountain, connecting the other sections of the Dragon Five Expressway, which have already been completed." Tian Ruifeng introduced that considering the construction site, large machinery into the inconvenience and other factors, the Shamaoshan Tunnel will be officially started after the completion of the bridge, and has now entered the stage of land acquisition and demolition.
"If the project is fully completed, it will take ten minutes from Changyang to Yidu Five Eyes Spring." Tian Ruifeng said that this project has greatly improved the situation of poor traffic inside and outside Changyang, and Changyang is a big step closer to the vision of "big county town" and "big traffic".
Integrate into Yichang half-hour economic circle
National Highway 318 Changyang is rocky, obliquely connecting a two-way 4-lane first-class highway, extending to the north, and driving a short time to the Jigongyan Tunnel. The tall Jigong Rock is the boundary mountain between dianjun and Changyang, and through the tunnel is the dianjun.
This is the Yichang to Changyang Expressway, starting from the intersection of Jiangnan 2nd Road and South Station Road of the Dianjun Military Region, entering the tunnel in Jigongyan in Quanshui Village, Liantang Township, exiting the tunnel in Meizi Bay, Changyang Jinbin Village, crossing the Shanghai-Chongqing Expressway under the partial rock, crossing Danshui, and ending at Tujiayuan Square in Changyang Longzhouping Town. The total length is about 27.84 km, 4 lanes in both directions, and the design speed is 60 km / h.
On October 26, the reporter saw during an interview on the Yichang Expressway that the 7.9 kilometers from the Changyang Jigongyan Tunnel to the partial rock section of the expressway and the 2 kilometers from Tujiayuan Square to Jinyangkou have been completed and have the conditions for opening to traffic. Kang Weibin, project director of the Changyang section of yichang expressway, introduced that the next step will be greening construction on both sides of the road.
Inside the Jigongyan Tunnel, the cable and lighting systems have been installed, and construction workers are welding ventilation equipment brackets. Kang Weibin introduced that the tunnel only has one last installation task left, and only needs to be connected to the external power supply, which has the conditions for opening to traffic.
The Jigongyan Tunnel is a key control project of the Yichang Expressway, with a total length of 2.55 kilometers, and the double tunnel was completed at the end of 2019. Kang Weibin introduced that the rock formation here is broken and belongs to a high-risk level tunnel. In the previous construction, in accordance with the principle of "first detection, pipe advance, short advance, weak disturbance, strong support, fast closure, and diligent measurement", various effective measures were taken to overcome construction problems such as poor geographical conditions, large changes in the surrounding rock of the tunnel, and difficulties in material transportation, and achieved the goal of penetrating earlier than the original planned time.
As soon as the Jigongyan Tunnel came out, it was Quanshui Village, Liantang Township, Point Military Region, and the viaduct of successive tunnels was being paved. According to reports, the 8.6-kilometer subgrade of the military section of the Yichang Expressway has been completed, and Changyang will soon be connected to the Yichang Half-Hour Economic Circle.
According to reports, the Yichang Expressway will connect the Longwu First-class Highway under construction and become a new section of G241. At that time, Longzhouping Town will become the development of the Central Urban Area of Yichang, and the Yangtze River will link with the new node of the Qingjiang River, and completely open up the "north-south longitudinal traffic artery" from Yichang to Changyang.
Touch the dream of "big county big traffic"
The reconstruction project of the 318 National Highway Yidu Safflower Set to Changyang Partial Rock Section (Changyang Section) just connects with the Yichang Expressway. Spreading out the traffic map, the two roads just form a three-way fork of traffic here in the side rock.
"In the future, tourists who drive to Qingjiang Gallery will directly enter the G318 first-class road under the Shanghai-Chongqing Expressway and turn into the Yichang Expressway at the rocky place, so that they can avoid the county town and relieve the traffic congestion in the county." Wang Chuncheng, commander of the reconstruction project of the 318 National Highway Yidu Safflower Set to Changyang Partial Rock Section (Changyang Section), introduced that the Changyang Section project starts from Sunjiawan at the junction of Yidu and Changyang and ends at the Partial Rock, and the total length of the project route is 16.36 kilometers. Previously, the reconstruction project of the Yidu section has been completed and opened to traffic.
"Changyang is the old rule of the ancient Wa Mountains, the peaks are staggered, the bamboo baskets are dense, and the natives chisel trails in the belly of the mountain, which are not wide and not large, and travel through the trees." The "Chronicle of Changyang County" said: "Kangzhuang is not in the whole territory. "In 2003, the two major national transportation campaigns were launched in Changyang Tujia Cottage, and the Yiwan Railway and the Shanghai-Chongqing Expressway began construction in Changyang at the same time, and were completed and opened to traffic in 2010, which greatly alleviated the traffic operation pressure of National Highway 318.
At the site of the reconstruction project of National Highway 318, the reporter saw that workers were installing steel wire mesh along the construction route. Yang Wanxi, manager of the project department of the construction party, told reporters that this is to prevent the construction of rolling stones from crushing the vegetation. At another construction site, large machinery was working on pile foundations, and the rumbling sound reverberated in the valley.
The old 318 National Highway is a dangerous "turnaround" and is a section prone to traffic accidents. Yang Wanxi introduced that after the reconstruction, the viaduct will be used to "cut the bend and straighten the original road section" to improve safety. It is understood that there will be 16 large, medium, and small bridges after the reconstruction of this section of less than 17 kilometers of pavement, which is scheduled to be completed in 2025.
At that time, the 241 National Highway and the Yiwan Railway, the Flipping Dam Expressway, the Shanghai-Chongqing Expressway, the 318 National Highway and the 324 Provincial Highway will form a three-dimensional traffic pattern.
