In 2017, during a routine assessment of the TH 41 Bridge 37D in Hartland, which traverses Route I- 91, bridge inspectors with the State of Vermont Agency of Transportation (VTrans) observed areas of heavy saturation, cracking, and efflorescence in the deck and pier caps. This evidence of deterioration led them to classify the deck and joints as being in “poor” condition. However, the superstructure and substructure were in “good” and “fair” condition, respectively.
