On the morning of June 30, 2021, the mobilization for the reconstruction and expansion of the Shuangbu-Hetao section of the Qinglan Expressway and the opening ceremony of the urban construction and transportation project were held at the scene of Huazhong Road, Hongdao Street, Chengyang District. In addition, the new airport expressway connection line (Shuangbu- Xiazhuang section) surface road project, Huazhong Road through project, Licunhe Interchange ABF ramp project, Taiyuan Road east extension project opened to traffic.

The Qinglan Expressway Shuangbu-Hetao section project is invested and constructed by Qingdao Transportation Development Group, including the main line and the connecting line. The main line starts from the west side of the current Qinglan Expressway Qingdao West Toll Station in the east, and at the starting point of the Nugukou Bridge, along the existing Qinglan Expressway to the west, and ends at the Hetao Interchange Interchange. The total length is about 15.7 kilometers. It is a two-way eight-lane expressway. Renovation and expansion of technical standards. The connecting line starts from the main line toll station on the north side of Qinglan Expressway in Qianyang Interchange, and goes south along the current Huazhong Road, connecting with the Gulf Bridge, with a length of about 6.9 kilometers. After the completion of the project, the first phase of the new airport expressway, the new airport expressway connection line (Shuangbu-Xiazhuang section), and Huanwan Avenue will be efficiently connected, which can effectively alleviate the "stuck neck" traffic between Jiaodong International Airport and the main city. Bottleneck problem.

Four major traffic projects

The Huazhong Road through project is the pre-implementation section of the reconstruction and expansion project from Shuangbu to Hetao section of Qinglan Expressway. The project is 773 meters in length and is designed according to the standard of two-way six-lane. This section of the road has not been fully connected for many years, which greatly restricts the ability of the Huazhong Road to be relieved. After the project was opened to traffic, the regional traffic bottleneck was broken in one fell swoop, in response to the eager expectations of all sectors of society, and will effectively promote the joint development of the north bank urban area and the east-west bank urban area.

The Licunhe Interchange is a hub interchange of Huanwan Road and Jiaozhou Bay Bridge and its connecting lines. The ABF ramp project is located at the starting point of the first phase of Jiaozhou Bay Bridge, including ramp A 330 meters, ramp B 309 meters, and ramp F 258 meters. The distribution lane is 948 meters, and the entrance to the north toll station is widened. After the project is completed and opened to traffic, there will be no toll for vehicles passing the ABF ramp, which will truly give full play to the "interconnecting" function of the Licunhe Interchange, connecting the Jiaozhou Bay Bridge with urban roads, and greatly improving the traffic capacity of the roads around the node.

The new airport high-speed connection line (Shuangbu-Xiazhuang section) is an important part of the "seven horizontal and nine vertical" high-speed road network in Qingdao's central urban area and the "three vertical and five horizontal" rapid road network in Dong'an urban area. It is also the Jiaodong International Airport. Important supporting roads. The project starts from the Nugukou Bridge in the west and ends at Qingyin Expressway in the east. The entire line is dominated by viaducts, with a length of about 9.8 kilometers, and simultaneous implementation of two-way 6-lane ground roads. The project will start at the end of 2019, and comprehensively promote technological innovations such as prefabrication, multi-pole integration, and imitation of stone roads. The highway system will be completed one year in advance and will be put into use in conjunction with the new airport transfer. The surface road system will be put into use on June 30 The daily opening to traffic is of great significance for strengthening the new airport’s traffic security system, boosting the transformation and development of surrounding areas, and improving the traffic environment on both sides.

The east extension section of Taiyuan Road starts from the New Jiaoji Railway Line in the west, and sets up and down ramps to connect to the west square of North Passenger Station along the eastward line, and turns right on Anshun Road to Taiyuan Road ramp to connect to the East Square, and continues eastward across the planned Anshun Road before landing , Connected to Siliu Middle Road in the form of a surface road, the length is about 1.2 kilometers, and construction will start in August 2020. The completion of the project and the opening to traffic will further optimize and improve the traffic dispersing road network system of the North Railway Station, and effectively strengthen the traffic connection between Huanwan Road and the elevated road of the cross-sea bridge.

In the first half of 2021, the first phase of the Qingyin Expressway Licun Toll Station Congestion Control Project was completed and opened to traffic. Shuangji Road (Luojiaying Section) was fully connected, and 7 unconnected roads including Yunling Road and Changzhou Road were opened. At the same time, the construction of the Dagu River Bridge on National Highway 204, the Dagu River Bridge on Lan Road, and 20 unconnected roads including Yichang Road and Jianshui Road were newly started. In the first five months of 2021, Qingdao’s transportation infrastructure construction has completed a total investment of approximately 14.46 billion yuan, a year-on-year increase of 12%, achieving a good start for the "14th Five-Year Plan" high-quality development.

The 4 projects opened to traffic this time and the 1 newly started project are all key transportation infrastructure projects and major livelihood improvement projects in Qingdao, as well as important passages and key points for the comprehensive transportation system around Jiaozhou Bay and the collection and distribution system of Jiaodong International Airport. The node is of great significance for breaking the regional traffic bottleneck, improving the travel environment of citizens, promoting the development of circum-bay linkage, and improving the radiation capacity of Jiaodong International Airport.
