As a transportation corridor that links No. 321 National Highway with urban municipal roads, Zhaoqing Avenue in Guangdong has witnessed the city's development and expansion. Today, it plays a key role in positioning Zhaoqing as a gateway hub connecting the Guangdong-Hong Kong-Macao Greater Bay Area (GBA) to the Southwest. The saying, "A road leads to prosperity in all industries", comes to life on Zhaoqing Avenue. From dusty tracks to tree-lined boulevards and quiet suburbs to vibrant cityscapes, the avenue witnesses not only Zhaoqing's development but also the city's evolving urban vision, connecting Zhaoqing with the future of the GBA.

作为321国道与城市市政道路融为一体的交通廊道，广东的肇庆大道见证了城市的发展、扩张，如今正助力肇庆打造粤港澳大湾区面向大西南的门户枢纽。“一路通，百业兴。”这句朴素而深刻的俗语，在肇庆大道上得到了生动的体现。从尘土飞扬到绿树成荫，从荒芜郊区到繁华都市，肇庆大道见证了肇庆的发展，也见证了城市发展理念的转变和提升，将肇庆与粤港澳大湾区的未来紧密相连。
