Traffic Control Information and Bypass Scheme of Yibin Fu Hydropower Station Reservoir Area

Attention, Yibin, Sichuan. 206 Sui Jun Highway from Yibin to Zhizhi County has been rebuilt, and the bridge needs to be renovated. For a long time, the weathering on both sides of the road is obvious. Especially in rainy days, these hidden dangers will endanger the safety of vehicles and pedestrians, and the following traffic control will last for 10 months.

In S206, due to the dangerous bridge construction in the reservoir area 1 1 of Frye Hydropower Station in Gaoxian County, Suiyun Road, the road from Gao Yi Road Frye Maintenance Station to Fujiang Xijiang Temple will be closed for about15km! The road has been closed for ten months!

Traffic control content 1. All vehicles and pedestrians are prohibited from passing during the renovation of dangerous rock disasters on high slopes in deep roots.

2. During the demolition and reconstruction of Gong Xi Bridge, no other vehicles are allowed to pass except pedestrians and two-wheeled motorcycles.

3. During the demolition and reconstruction of the steep water bridge, vehicles with two axles less than 20 tons and one-way vehicles can pass through the temporary service road.

4. Other bridges are limited to one-way traffic for vehicles under 20 tons.

Specific construction scheme: Gong Xi Bridge and Steep Water Bridge are constructed in staggered time, that is, the Steep Water Bridge and deep-rooted high slope are closed in advance to control the traffic of other bridges. After the steep water bridge and deep-rooted high-slope roads are open to traffic, the Gong Xi Bridge is closed to traffic.

Control time: 20 19 12.7, traffic construction will be closed, the main project will be completed before September 30, 2020, and traffic control will be cancelled.

Bypass route of vehicles during the control period:

Three-axle and above trucks pass through the G547 line in Yibin city? S436 line (formerly Yiwei Road)? G246 line goes to Gongxian County, Chang Xun? Go to Liugongyan, Gaoxian County via G246 line? S206 Suiyun Road detours.

Two-axle trucks under 20 tons pass through S206 Suiyun Road to Feilai Town, Gaoxian County → XQ29 Laisha Road →S2 12 Yiqing Road → Qingfu Town, Gaoxian County →S206 Suiyun Road or bypass other nearby roads according to the requirements of load limit grade.

Passenger vehicles pass through S206 Suiyun Road to Gaoxian County to Frye Town? Come to Sha Road via XQ29? Yiqing road S2 12? Qingfu Town, Gaoxian County? S206 Suiyun Road detours.

At the end of the last century, in order to meet the storage time requirements of Feilai Hydropower Station in Nanguanghe, Gaoxian County, the reconstruction of Suiyun Road in Yibin to Zhigao County in S206 was restricted by construction investment and other factors. Some bridges were only lifted and rebuilt on the old bridges built in 1950s, and the newly excavated earth-rock slopes were not protected.

After the impoundment of Nanguanghe Frye Hydropower Station in 2002, most of the bridge substructure along the line was flooded for a long time. After more than ten years of operation, the municipal highway department entrusted professional bridge detection units to carry out detection:

There are 1 1 bridges in the section from Frye to Xijiang Temple, including 4 dangerous bridges of Grade IV and 7 bridges of Grade III.

Due to different degrees of weathering, dangerous stones appear on the highway slope in this section.

Especially on the deep-rooted high slope, the hidden danger of dangerous rocks is the most prominent. Earth-rock collapse occurs almost every year in flood season, which seriously endangers the traffic safety of vehicles and pedestrians.
