• Abstract:
  This project allowed the continuation of collecting monitoring data from Bridge #6139061300401 in the John James Audubon Project
  
  for an additional two-year period. Bridge #6139061300401 was instrumented as part of an earlier project (LTRC Project No. 08-1ST),
  
  whose fi ndings raised questions about its performance under thermal gradients, which warranted resuming data collection to monitor
  
  the performance of Bridge #6139061300401 over a longer period of time. The focus of the monitoring eff ort for both projects is on
  
  the employed continuity detail, which transfers forces between adjacent girders via positive moment reinforcement based on the
  
  recommendation of the National Cooperative Highway Research Program (NCHRP) Project 12-53. Continuity details are typically used
  
  to eliminate the need for high-maintenance joints that often lead to the acceleration of element deterioration in the vicinity of the
  
  joints.
