Abstract: The promotion and application of scientific and technological innovation in highway tunnels construction in Zhejiang province, China, must be accelerated. Therefore, the development process of highway tunnel construction in Zhejiang in recent decades is reviewed, and the recent scientific and technological achievements in tunnel engineering in Zhejiang are summarized. These include three representative achievements in special tunnel construction technology, safe and energysaving operation technology, and tunnel maintenance technology. Furthermore, the shortcomings of highway tunnels in Zhejiang are analyzed, such as the construction quality defects of drilling and blasting methods, the low degree of mechanization and informatization of drilling and blasting methods, the low proportion of TBM or shield methods, less application of new intelligent technology, and lagging application of preventive maintenance and equipment technology. Finally, the three key future developmental directions of safety, intelligence, and green tunnel engineering in Zhejiang are discussed.
