摘要： 随着我国经济的发展，部分在役高速公路出现交通拥堵等问题，不能适应社会经济发展需求。充分利用现有高速公路资源，可以提高通道运能与服务水平，有利于减轻环境污染，适应科学发展需求。对原有桥梁扩宽需要考虑新旧桥梁的联系，新建桥梁部分扩宽措施不合理会导致改扩建桥梁出现各种问题。结合工程项目介绍高速公路拼宽桥梁设计，提出桥梁设计优化措施。
Abstract: With the development of China's economy, some in-service expressways have problems such as traffic congestion, which cannot meet the needs of social and economic development. Making full use of the existing expressway resources can improve the channel transport capacity and service level, which is conducive to reducing environmental pollution and adapting to the needs of scientific development. The expansion of the original bridge needs to consider the connection between the old and the new bridge, and the unreasonable measures for the expansion of the new bridge will lead to various problems in the reconstruction and expansion of the bridge. Combined with the engineering project, the design of the highway split-width bridge is introduced, and the optimization measures of the bridge design are proposed.
