• Abstract:
  This research report used a pilot project to examine the Migratory Bird Treaty Act (MBTA) and how Colorado Department of Transportation (CDOT) transportation improvement projects may result in noise and vibration levels that could affect migratory birds. The pilot project examined the vibration and noise levels that occurred as a result of standard maintenance activities on structure E-16-P along Sheridan Boulevard over Clear Creek. Noise and vibration data collected between September 14, 2017 and November 25, 2017 showed distinct spikes in vibration on the bridge during expansion device demolition and bridge deck repair. There was a prolonged spike in vibration frequency during milling on the bridge. Due to limitations in the data of the study, it is unknown whether the peak levels of vibration and noise measurements would negatively impact migratory birds nesting on the structure. This pilot project helps inform CDOT or other agencies how to investigate the subject in more depth in the future.
  
  Implementation: The results of this pilot study demonstrate that noise and vibration impacts from construction activities can be studied using methodology similar to that carried out here, but a larger sample of bridge types and construction activities will better inform decisions. The compiled data from this pilot project and additional studies can be used to determine whether certain bridge maintenance activities will be exempt from MBTA regulations due to minimal levels of disturbance to nesting birds.
