The construction of the transportation network is not only related to people's livelihoods but also affects the business environment and economic development. Building a smooth transportation network will activate new vitality in regional development and fully unleash development space and potential. Dunyu Road is the main connecting line between the Xihu Science Park, the Zijin Mingzhu area, and Xihu University. Its opening will further promote the urbanization process of the western part of the city and is of great significance to the construction of the Western Hangzhou Science and Technology Innovation Corridor.
