In the history of Chuansha, internal and external transportation was mainly by waterways. All major market towns had markets near the water, and there were passenger flights between the market towns and to the Shanghai pier. Since the Shangchuan Railway was completed and opened to traffic in the 10th year of the Republic of China (1921), land transportation has been facilitated. Local construction undertakings are also increasingly developed. Before the founding of the People's Republic of China, the county's river channels were narrow and could only accommodate ships of 5 to 10 tons. After the founding of the People's Republic of China, through vigorous excavation and dredging, the navigation capacity was greatly improved. By 1985, most of the 24 major rivers were navigable for ships of more than 30 tons, and 4 were navigable for ships of 100 tons.

After the founding of the People's Republic of China, with the development of highway construction, by the late 1950s, passenger transportation was gradually replaced by buses and cars. In 1985, there were 44 roads in the territory, with a length of 252.27 kilometers. Rural mechanical roads are densely spread vertically and horizontally, connecting all villages. Before the liberation of Sichuan and Shaanxi, there were nearly 4,000 bridges of various types, most of which were small wooden bridges and old-fashioned masonry bridges, and very few of them could pass cars. Since the 1960s, all highway bridges have been renovated into cement structures, which can generally accommodate trucks with a capacity of 15 to 20 tons, basically adapting to the development of the local economy. In the early years of the Republic of China, the inner and outer seawalls of the Chuansha Highway served as the backbone of north-south transportation. In the spring of the 14th year of the Republic of China (1925), Datong Road (Tian Dengkou Lunbu - Gaoqiao Town) was built in Gaoqiao Township. In December of the 19th year of the Republic of China, the Shanghai Municipal Public Works Bureau built Pudong Avenue along the Huangpu River connecting Shangchuan and Shangnan Roads. The earthwork was completed in August of the following year, and the road construction was extended to October of the 24th year of the Republic of China. In the winter of the 23rd year of the Republic of China, Pudong Automobile Company invested in filling Gugao Road (Gulu-Donggou) with the soil dug up from the Zhaojiagou river. In October 1935, Pu Construction Company advanced funds to build the Zhoupu-Tangqiao section of the Shanghai-Nan Highway. In the spring of the following year, the roadbed project was completed. In August, the road surface was completed. By the time of liberation in 1949, there were 18 roads in the territory.

In July 1949, in conjunction with the emergency seawall repair project, in September and October, two simple access roads, Ougao Road and Caogao Road, were completed to communicate with Datong and Dongtang roads. From 1956 to the early 1960s, county highway construction experienced great development, with 17 new highways covering a length of 89.85 kilometers. Among them, the North Sichuan Highway (Beicai-Xiaoyingfang) traverses the county from east to west and intersects with Hunan and Sichuan South Roads. Yanggao Road (Yangsi Shangnan Road-Gaoxing) runs through the north and south, connecting Shangnan, Hunan, Shangchuan, Gugao and other roads, becoming a trunk road in the county. In the mid-1960s, 5 new roads were built one after another, with a length of 18.83 kilometers. In 1975, in accordance with the requirements of the Ministry of Transportation that all communities and factories should be connected to roads, 6 new roads were built in the county, with a length of 20 kilometers. Reconstruct the Shangchuan Railway into a highway. By 1985, there were 44 roads (sections) maintained by the county, with a total length of 262.27 kilometers. There are 3 roads (sections) not maintained by the county, with a length of 17.99 kilometers. Shangchuan Railway

In January of the 10th year of the Republic of China, Huang Yanpei, Zhang Zhihe, Gu Lanzhou and others initiated an IPO to raise funds and organized Shangchuan Transportation Company. In October of the 13th year of the Republic of China, Shangchuan Transportation Co., Ltd., Shanghai Pudong Tanggong Rehabilitation Bureau and Sichuan Transportation Company The Shaxian County Transportation Bureau entered into a contract to lease the Shangchuan County Road (Qingning Temple - Chuansha County) to lay light rails and run railway locomotives, and obtained a 30-year franchise. On October 3, 2014, the track laying of the section from Qingning Temple to Gongjia was completed and opened to traffic. On July 10 of the following year, the track project to Sizao Port in Chuansha continued to be completed. The Shangchuan Railway is 21.15 kilometers long and has Qingning Temple, Jinjiaqiao, Xinlu, Shaojialong, Caojia Road, Gongjia Road, Dawan, Xiaowan, Muziqiao and Chuansha stations. Passenger cars are towed by diesel locomotives and connected with the Pujiang Ferry of Tanggong Bureau to reach downtown Shanghai. Passengers in Xiaoputuo, Zhuqiao, Nanhui and Datuan areas south of Sichuan and Shaanxi Province are picked up by private ferries rented by the company and self-owned passenger ships. At the beginning of the 20th year of the Republic of China, the company changed the wooden bridges along the line to steel bridges. A steam locomotive was purchased from a German businessman and put into operation in September 22nd of the Republic of China. In May of the 23rd year of the Republic of China, the company signed contracts with the Chuansha County Government and the Nanhui County Government respectively to lease Chuanqin County Road and Nanchuan County Road. In November, the railway was extended eastward from Chuansha to Qintang, and a small barracks station was set up. On March 15, the 25th year of the Republic of China, the railway was expanded southward to Zhuqiao Town, and Jiangzhen, Dengzhen and Zhuqiao stations were added. So far, the Shangchuan Railway runs through Shanghai, Chuansha and Nanhui. The total length is 35.35 kilometers, and the total capital raised is 678,200 yuan.

Highways and bridges were built in Chuansha during the Republic of China. In the 10th year of the Republic of China (1921), two wooden bridges were built on Shangnan Road. In the 11th year of the Republic of China, 17 steel plate bridges and cement arch bridges were built on Shangchuan Road. During the Anti-Japanese War, highways and bridges in the county suffered serious damage, and 26 of them along the Shangchuan Railway were blown up by Japanese planes. On the eve of liberation, highways and bridges were destroyed by the Kuomintang troops. The first cement arch bridge of the Shangchuan Railway, the first south bridge of Jinjia Bridge, the second Xinlu Bridge, the first iron bridge and the second cement arch bridge of Shaojialong North were blown up. Five steel-reinforced concrete bridges on Hunan Road were also blown up, and two Meisong bridges and two Meisong bridge decks were burned down.

According to a survey at the end of 1949, there were 34 Shangchuan and Shangnan railway bridges and 37 highway bridges in the county, including 7 Hunan Road, Chuanbei Road, Huchuan Road, Xiaobai Road and Chuanqin Road. There are 5 blocks each on county roads, 2 blocks each on Caigao Road, Datong Road, and Dugao Road, and 1 block each on Minsheng Road, Hengda Road, Haigao Road, and Dongtang Road.

After liberation, the government immediately organized efforts to repair the damaged bridges. While repairing the Gaoqiao seawall, eight more wooden bridges were built on Caogao Road and Ougao Road. Gaoxing Road was built in 1953, Chuanying Road was rebuilt in 1954, and 8 wooden bridges were built. In 1956, 13 bridges were built on Yanggao Road. They were the first batch of concrete structure bridges built after the founding of the People's Republic of China. They were designed by Shanghai Municipal Engineering. Designed by the Institute and constructed by Shanghai Urban Construction Bureau No. 4 Engineering Zone. Bridge structure: The upper part is a row of rack-type piers and stone cone slopes; the lower part is a T-shaped concrete girder.

In 1964, the County Highway Management Office established a bridge team to rebuild temporary wooden bridges in the county in batches and phases. The first one was the Yujiabang Bridge on Hunan Road, which was then reconstructed from Hunan Road, North Sichuan Highway, Zhouzhou Highway, South Sichuan Highway, to Caogao Road, Haixu Road, etc. By the end of 1969, the reconstruction was basically completed. In 1975, the Shangchuan Railway was rebuilt into roads and bridges were rebuilt, which took two years to complete. In 1978, two main river channels, the Pudong Canal and the Chuanyang River, were excavated, and 10 cross-river highway bridges were completed in more than a year. In 1980, Chengxiang Town built a ring road and reconstructed 4 bridges. From 1980 to 1982, among the bridges built by the bridge team, the ones rated as the best engineering bridges by the Municipal Urban Construction Bureau include: Xinkaihe Bridge on Hunan Road, Chuanyang River Bridge on Shangnan Road, Chengnan Road Bridge in Chengxiang Town, Sichuan Huanxi Bridge There are 9 bridges including Tongcheng River Bridge and Miaojing Bridge on Junmin Road, Bridge No. 10 on Yanggao Road, Xinlu Bridge on Shangchuan Road, and Dongfeng Bridge on Chuanliu Road.

By the end of 1985, there were 202 highway bridges in the county, with a total extension of 5,400 meters, including 72 trunk highway bridges and 130 county highway bridges. There are 20 bridges in the 3 towns under the county.
