随着机动化水平不断攀升,道路交通量的不断发展,国内各大城市道路服务水平难以满足需求。为了应对不断增长的交通需求,各大城市均在开展快速路的建设工作。以宁波北环东延镇骆路跨线桥为例,结合跨线桥现状运行状况、沿线重大管线及周边用地等因素,分析新建快速路与现状跨线桥间关系处理的特点,展现方案设计思路。

With the increasing level of motorization and the continuous development of road traffic,the roads of major cities in China are difficult to meet the service level requirements.In order to adapt the growing traffic demand,major cities are carrying out the construction of expressways.This paper took Zhenluo Rd.Overpass Bridge in Ningbo East Extension project of North Ring as an example and analyzed the characteristics of the relationship between the newly constructed expressway and the current crossover bridge in combination with the current operation status of the overpass bridge,major pipelines along the expressway and surrounding land use.Design ideas of the scheme are presented as well.
