Which highway is the S7 code for?

[Orville]

Highway S7 code refers to the Huchong Expressway. The Huchong Expressway, formerly known as A13 Highway, Chongming Cross-River West Line, and Riverside Expressway (Phase II). The S7 Expressway starts from the northwest section of Shanghai Outer Ring Expressway and ends at the Chongming section of Hushan Expressway, with a total length of approximately 28.7 kilometers. The principles for naming national expressways are as follows: 1. The naming of national expressway network routes should follow the general rules of highway naming. 2. The names of national expressway network routes are composed by adding a hyphen "－" between the starting and ending place names in the order of the route's start and end points. The abbreviated name of the route is represented by the first Chinese character of the starting and ending place names, or by the abbreviation of the province (city) where the starting and ending points are located. 3. The names and abbreviations of national expressway network routes cannot be repeated. 4. When two or more sections have the same starting and ending points, they are arranged in order from east to west or north to south.

As a regular driver who frequently travels in the Jiangsu-Zhejiang-Shanghai region, I've driven on the S7 highway several times. This road is actually the Shenjiahu Expressway in Shanghai, connecting cities like Shanghai, Jiaxing, and Huzhou. I remember it's part of the provincial highway network, marked as S7 on the road signs, and the drive is quite smooth, especially the section from Jiading to Huzhou, which offers nice scenery with glimpses of water towns. However, during holidays, the traffic volume is enormous, and starting at 8 or 9 AM often means getting stuck near toll stations—I recommend bringing some snacks and drinks to avoid hunger. The service areas are well-equipped; for example, the fast food at Jiashan Service Area is decent, though fuel prices are slightly high, and the air conditioning needs to be cranked up in summer for comfort. Watch your speed while driving, as the limit is generally 120 km/h, and there are many speed cameras—speeding easily leads to fines. Overall, it's a practical route often chosen for short weekend road trips.

I usually study highway numbering systems. In China's expressway network, S7 is classified as a provincial-level road, specifically referring to the Shenjiahu Expressway in Shanghai. This route starts from Shanghai, traverses through Jiading and Qingpu districts, and extends all the way to Huzhou in Zhejiang Province, covering a total distance of approximately 150 kilometers. It was fully opened to traffic around 2020. Driving on this expressway is quite safe, as the road surface is well-maintained, and even rainy conditions don't pose significant hazards. During my drives, I've noticed that the service areas along the route are clean and tidy, equipped with gas stations and convenience stores, making rest stops very convenient. Additionally, with the widespread adoption of the ETC system, there's no need to waste time queuing at toll stations. This expressway connects the Yangtze River Delta economic zone, facilitating both freight transport and travel efficiently. However, frequent congestion occurs during peak seasons, so it's advisable to leave early to avoid rush hours. Moreover, navigation apps can display real-time traffic information for S7, which I highly recommend to enthusiasts who enjoy exploring long-distance routes.

Last time, I went on a road trip to Huzhou with friends via the S7 Expressway, also known as the Shen-Jia-Hu Highway, which starts in Jiading, Shanghai. The drive was super easy—clear road signs made it simple to follow even if you didn't know the names, and we arrived in less than two hours. We stopped at the Jiaxing service area along the way to take a break and bought some affordable and tasty snacks. The entire route had light traffic, making for a smooth drive, and we maintained a speed of 110km/h with safety as the top priority. This route is perfect for young people looking for a short getaway—it's budget-friendly and time-efficient. Just remember to check the weather and traffic info in advance to avoid slippery roads on rainy days.
