On September 26, the Changqing section of the Jinan-Heze section of the Jinan-Heze section of the Jinan-Heze section of the Jinan-Guangzhou Expressway invested and constructed by Shandong High-speed Group (Yinjialin hub to Xiaoli interchange) resumed traffic in the Jinan direction, marking the first "two-way eight-lane" traffic section of the Jihe Expressway on the whole line. The Changqing section is 41.3 kilometers long, and the Yinjialin Hub, Songzhu Hub, Changqing University Town, Changqing, Xiaoli 3 interchange toll stations and Changqing service area will resume full operation simultaneously, and the transportation convenience efficiency and carrying capacity will be greatly improved.
Jihe Expressway was completed and opened to traffic in September 2007, passing through 9 districts and counties of 4 cities in the south of the economy, Tai'an, Jining and Heze, with an average daily traffic flow of 60,000 vehicles before the reconstruction and expansion, and the four lanes have been unable to better meet the needs of the public. The reconstruction and expansion project was included in the province's "14th Five-Year Plan" and the list of major implementation projects, with a mileage of 152.7 kilometers, a two-way eight-lane expressway standard, and a design speed of 120 km/h.
The project was launched in May 2021 and completed the preliminary work in only 7 months, setting a new record for similar work in the province. Since the full start of construction in October 2022, the project will complete the widening and reconstruction of half width by the end of 2023 in accordance with the traffic organization plan of "half-width closed construction and half-width one-way protection", and the traffic in the direction of Heze will be fully converted to the new half. As of the end of September this year, the whole line base, pavement and other projects have been nearly completed, and have entered the stage of closing and opening to traffic. Next, the project will resume two-way traffic in different sections to ensure that the whole line will be connected in both directions by the end of the year, and will inject new vitality and impetus into the economic and social development of the regions along the line.
During the construction process, the project also completed the transformation and upgrading of the toll stations of the whole line based on the "cloud charging" standard, and the traffic efficiency and driver experience have been significantly improved. In addition, with the goal of building "the country's first zero-carbon high-speed reconstruction and expansion", the project actively promotes the simultaneous construction of distributed photovoltaic power stations and the main project of reconstruction and expansion.
