It is connected to the existing G207 line with a total length of 96.178 kilometers.

It is understood that the project adopts the first-class highway standard construction, the design speed is 80 km/h, the two-way four-lane and six-lane sections are adopted, and the subgrade width is 25.5 meters and 33 meters. On the whole line, there are 4 places on the high-speed, 3 places on the railway, and 3 places on the railway. There are a total of 50 bridges of 1,1894.5 meters, 4 interchanges, 32 light-controlled level crossings, 2 service areas, 2 maintenance work areas, 2 supervising stations, and 1 main line toll station. The estimated total investment is 6.95 billion yuan, and the construction period is 42 months. It is planned to be completed and opened to traffic in September 2024.

Engineering: infrastructure construction, infrastructure projects, infrastructure projects

The reconstruction project of the Xiangyang section of the 207 National Road is an ordinary highway construction project with the longest construction mileage, the largest investment scale, the highest construction standards, and the most social attention in Xiangyang's history. In particular, the Han River Super Bridge, the main controlling project, in order to protect the ecology of the Han River and the navigation of the Han River, the main bridge adopts a two-hole 330-meter steel box composite girder single-tower cable-stayed bridge.
