The construction of a mountain expressway is critical to the development of the mountain economy and the creation of mountain areas. However, since the service life of many mountain expressways continues to increase, municipal transformation design is required to improve the smoothness of the expressway, make efficient use of space, and reduce resource waste. The author investigates the current challenges in the construction of a mountainous expressway and proposes an effective method for municipal reconstruction design of a mountainous expressway, in the hopes of assisting in the optimization and development of the mountainous expressway.
