Winnetuxet Road Bridge

Plympton, MA
Key Elements
  • Two-span timber bridge 
  • Bridge inspection and rating
  • Timber pile and concrete cap repair 

Nitsch provided structural engineering services to support the evaluation and inspection of an existing two-span timber bridge crossing on Winnetuxet Road in Plympton. The existing bridge superstructure was replaced in 2002 and the substructure had recent repairs. 

Nitsch performed a field inspection, identified structural deteriorations, and prepared a rating calculation of the timber pile bent. We used the results and findings of the inspection and rating to evaluate multiple repair and replacement options of the timber pile bent. We then prepared a structural report for the Town of Plympton in which we recommended that two of the four timber piles and the concrete cap be repaired. After reviewing the report, the Town requested Nitsch to provide structural engineering services for the repairs. 

After the design phase was complete, Nitsch oversaw the bid advertisement for construction and led all bid phase services. Once a construction contract was successfully awarded, we continued to provide construction administration services to the Town.
