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.
Key words: highway engineering；wide-split bridge；design practice
