改扩建市政道路跨越公路设计探讨

Discussion on Design of Reconstruction and Extension of Municipal Roads across Highways

摘要:

拟改扩建的市政道路需跨越现状高速公路，同时涉及现状高速收费站，需与收费站进出交通作衔接处理。为了保证穿越点车道规模不受影响，同时改善改造道路与收费站出入口的拥堵问题，设计方案通过多手段改造来实现拓宽，同时保障公路的日常运营不受影响。望通过此案例分享，为类似项目提供一定借鉴参考。

Abstract:

The municipal road to be reconstructed and extended needs to cross the current expressway, and also involves the current expressway toll station, which needs to be connected with the traffic entering and exiting the toll station. In order to ensure that the scale of the crossing point lane is not affected, and to improve the congestion problem at the entrance and exit of the reconstructed road and toll station, the design scheme achieves the road widening through the multiple means, while ensuring that the daily operation of highway is not affected, which can provide some reference for similar projects.
