摘　　要：在经济高速发展的今天,交通运输的安全与稳定变得越来越重要,甚至关系到了整个经济发展的安全。保障交通运输的安全与稳定是保障经济发展的首要条件。在我国的交通运输中,公路运输,尤其是高速公路的运输,是非常重要的一个部分。但是在以往设计高速公路的时候,尽管已经充分考虑到了未来的发展,但是在今天看来还是过于“胆小”。本文将浅析目前高速公路的发展现状,分析拓宽高速公路的意义,并总结和改进高速公路拓宽工程中新老路结合部的施工技术。With the rapid development of economy,the safety and stability of transportation become more and more important,even related to the safety of the whole economic development.To ensure the safety and stability of transportation is the primary condition for economic development.In our country's transportation,highway transportation,especially expressway transportation,is a very important part.However,in the past,although the future development has been fully considered in the design of expressway,it is still too"timid"today.This paper will analyze the current situation of expressway,analyze the significance of widening expressway,and summarize and improve the construction technology of new and old road junction in expressway widening project.
