With the development of the economy and social progress, more and more cities begin the construction of urban expressways. During the construction process, it is inevitable to encounter the situations where expressways intersect with railways. Taking the bridge of Baoshan Road crossing Qingdao - Jinan Passenger Dedicated Line as an example, the key factors and scheme of expressway node involving railway are discussed and studied. Baoshan Road Expressway is the main expressway connecting the main urban area of Zibo with Huantai County and Zichuan County, and is also the key road for the rapid transformation between the main urban area and the expressway. As an important transportation node on Baoshan Road Expressway, the construction of the bridge for Baoshan Road crossing Qingdao - Jinan Passenger Dedicated Line will greatly alleviate the traffic congestion caused by railway separation, improve the travel efficiency of the citizens, and promote the land development and economic development along the local roads.
