N1 - The authors would like to express their gratitude to their supporters. Research work at the University of Auckland was supported by the Earthquake Commission Research Foundation grant UNI/578. Piotr Omenzetter’s work within The LRF Centre for Safety & Reliability Engineering at the University of Aberdeen is supported by The Lloyd's Register Foundation (The LRF). The LRF supports the advancement of engineering-related education, and funds research and development that enhances safety of life at sea, on land and in the air. NGA Newmarket facilitated the field testing and New Zealand Transport Agency allowed the use of Newmarket Viaduct for research. Gewei Chen, Shahab Ramhormozian and Peifen Chua, research students at the University of Auckland, assisted with the ambient vibration tests.

N2 - This paper presents the results of modal identification tests that were performed in a twelve span viaduct, located in Auckland, New Zealand, during construction and after completion. These tests are two extensive one-off ambient vibration tests using wireless sensors, conducted to evaluate the structural behavior of the viaduct. The modal identification tests comprised the measurement of accelerations in the structure induced by the usual vehicular traffic crossing over the viaduct. Output-only modal identification methodologies were used to analyze the data obtained in those tests, in order to identify the modal properties of the viaduct in the two different stages.
