ResumoKobe/Awaji Earthquake in 1995, called `The Great Hanshin Earthquake', occurred in heavily populated area of Kobe City and took away the lives of more than 6000 people. Hanshin Expressway Route 3 running through this area was also damaged hideously and forced out of service. The strategy of its restoration was not only to increase the seismic structural safety but also to improve the environmental safety along the route. As it is a lifeline route, the restoration was demanded to complete as soon as possible to save the economy of Kobe City. The route of 27.7 km was back into full-service in 623 days after the earthquake with new structural designs. In this report, the outline of the restoration work is described focusing on some newly adopted structures such as hybrid pier and environmental measures of low-noise pavement or new noise barriers.
