This speech is to briefly introduce the efforts in the US in earthquake hazard mitigation of transportation structures through a thorough and comprehensive seismic research program. This program initiated in the 1991’s Transportation Equity Acts (TEA) and has been working through three TEAs and funded more than $36 Millions in research tasks. The program focuses on three fundamental issues, which includes: (1) A State-of-the-Art’s Specifications in Seismic Design for all new highway constructions, (2) A State-of-the-Practice’s Manuals in Seismic Retrofitting for all existing highway constructions, and (3) A Systematic Risk Analysis Program to estimate the earthquake loss of the roadway system using network system approach. The most important factor to reduce or mitigate the earthquake loss of the highway infrastructure is through a well preparedness, including those above three items.
