This stage completes the Nestor Gambetta Freeway connecting the Callao Port Terminal with the Panamericana Norte Freeway. This phase comprises the construction of a tunnel, called “Túnel Callao”, that runs beneath the future second runway at the Jorge Chávez International Airport. It includes a 1 km cut-and-cover box structure and two approach ramps, which make a total length of 2.4 km. This facility resolves the inconvenient overlap between the new freeway and the airport expansion. It is located in a highly seismic area with a high water table. The paper presents an overview of the design and construction, with emphasis in seismic design. The design earthquake was determined based on the latest AASHTO criteria. The seismic design takes into account pressures and racking displacement demands. The racking displacements were based on site specific soil characteristics and state-of-the-art research on soil interaction analysis. In a final stage, performance-based earthquake engineering (PBEE) approach was applied in order to investigate and demonstrate that the tunnel seismic performance is adequate for big earthquakes. The state-of-the art-practice in tunnel seismic design was used in order to get a safe and economic structure and with a predictable seismic behavior.
