At the end of 2014, with the arrival of the China Railway Bridge Bureau's SHZQ-1 construction project, the construction of the Shangqiu-Hefei-Hangzhou Railway (referred to as the Shanghehang Railway) officially commenced. The main project of this section is the Wuhu Yangtze River Road-Rail Bridge, located 3.5 kilometers upstream from the already-built Wuhu Yangtze River Bridge, near Yiji Mountain. The bridge spans 5.4 kilometers and accommodates both Wuhu's urban rail transit Line 1 and an eight-lane urban main road. It is a combined road-rail bridge integrating a passenger dedicated line, urban rail transit, and urban main roads.

The Wuhu Yangtze River Road-Rail Bridge is a key project of the Shanghehang Railway and is the world's largest span road-rail dual-use cable-stayed bridge with a combination of high and low towers. The main span measures 588 meters, and the height of the No. 3 tower is 130.5 meters. This bridge features a deep-water bare rock setting for its steel caisson foundation and employs two domestically leading technologies: high-strength durable parallel steel wire cable-stayed cables with a maximum anchor point tension of 16,000 kN. The concrete admixture used in this project is the TK-PCA2 retarding high-performance water-reducing agent produced by Sichuan Tieke New Building Materials Co., Ltd., with a dosage of 1.0.

The Guanggan Expressway is a section of the G75 Lanhai Expressway (Lanzhou to Haikou), which is part of the national expressway network. It begins at the Jiangjunshi Road Tunnel in Gansu Province, traverses the Jiangjunshi area at the Sichuan-Gansu border, and then heads south through Shenjiashan. The route continues west to Qingchuan County in Guangyuan City, passing through Mengzigou, Mu Yu Town, Machang Township, and Guanyindian Township. It then crosses Zhaojiayan, spans the Tangjia River, and goes through Huachang in Baolun Town, crossing the Baocheng Railway and National Highway 108. Finally, it crosses the Qingjiang River to connect with the Mian Guang Expressway at Luojia Gully, linking with the starting point of the Guangyuan to Nanchong Expressway (Guannan Expressway). The total length of the route is 56 kilometers.

The Guanggan Expressway is constructed to a four-lane highway standard, with a designed driving speed of 80 kilometers per hour. The roadbed width is 24.5 meters, and there will be two rest areas and two interchange interchanges along the route.

This project is challenging, with a significant proportion of bridges and tunnels. The total length of the bridges is 18.789 kilometers, including 4 major bridges, 50 large bridges, and 9 medium bridges, with the longest being the Qingjiang River major bridge at 1,714.55 meters. Additionally, there are 12 tunnels along the route, with the longest being the Zhaojiayan Tunnel at 6,300 meters. The overall bridge-tunnel ratio is as high as 80%.

The Leya Expressway is a segment of the G93 Chengyu Ring Expressway planned within the national expressway network in Sichuan.

This road connects to the G93 Leyi Expressway at the Zhangxuba Interchange, passing through the city center of Leshan, Jiajiang County, and Hongya County in Meishan City, reaching Yucheng District in Ya'an City, and then connecting to the G5 Chengya Expressway at Mingshan County. The total length is 116.683 kilometers, with a design speed of 100 km/h. It is fully enclosed, with all interchanges, featuring a dual four-lane configuration. The total investment is 7.848 billion yuan, and construction officially began on December 23, 2009, with completion and opening to traffic in 2012.

Currently, the Chengyu Ring Expressway includes five completed highways: Chengmian, Chengya, Suiyu, Leyi, and Miansui. Highways such as Yilu and Yu are already under construction, with the Leya Expressway being the last to start. Once the Leya Expressway is completed, the 1,200-kilometer Chengyu Expressway loop will be fully connected. At that time, travel time between adjacent cities in the ring—including Chengdu, Ya'an, Leshan, Yibin, Luzhou, Chongqing, Suining, and Mianyang—will not exceed three hours by highway. This will also lead to the formation of the Chengyu urban agglomeration, which includes over 30 major, medium, and small cities, thereby promoting the development of the Chengyu economic circle.

The Lianghekou Hydropower Station, also known as the Yalong River Lianghekou Hydropower Station, is located on the mainstream of the Yalong River in Yajiang County, Ganzi Prefecture, Sichuan Province, approximately 25 km upstream from the county town. It serves as a control reservoir for the tiered hydropower stations on the middle and lower Yalong River, significantly impacting the overall development of Yalong River hydropower projects.

The primary purpose of the station's development is power generation, while also providing functions such as water storage and energy regulation, alleviating flood control tasks for the middle and lower reaches of the Yangtze River, and improving navigation conditions during dry seasons. Its economic benefits are quite remarkable. The dam site is located about 1.8 km downstream from the confluence of the Qingda River on the mainstream of the Yalong River, controlling a catchment area of 65,599 square kilometers.

This project is located in the Jinsha River Canyon at the border of Ningnan County in Liangshan Yi Autonomous Prefecture, Sichuan Province, and Qiaojia County in Yunnan Province. It is the second stage of the four-tier development of the lower Jinsha River (from the mouth of the Yalong River to Yibin). The project primarily focuses on power generation, while also providing benefits such as sand retention and irrigation. The reservoir's normal water level is 820 meters, with a total capacity of 18.8 billion cubic meters and a regulating capacity of 10 billion cubic meters. It has seasonal regulation capabilities, which can increase the guaranteed output during dry periods for the downstream Xiluodu, Xiangjiaba, Three Gorges, and Gezhouba power stations to 2.2 million kilowatts, adding 5.5 billion kilowatt-hours of electricity during dry seasons. The main structure consists of a hyperbolic arch dam, an underground powerhouse on the right bank, and a flood discharge and sediment flushing system. The hyperbolic arch dam is 270 meters high.
