Leonard P Zakim Bunker Hill Bridge

MassDOT District 6 (Massachusetts Turnpike Authority)

Project Summary

TranSystems was selected by MassDOT District 6 (Massachusetts Turnpike Authority) to provide bridge inspections on complex and noncomplex structures at locations statewide. The contract was originally prepared for the inspection of new bridges built as part of the former Central Artery/Tunnel project north of the Charles River. However, TranSystems mobilized quickly upon selection and award, and our scope of work was expanded to include the routine inspection of bridges on the Turnpike Extension (east of Route 128).

TranSystems has also provided all-item inspection of the Leonard P Zakim Bunker Hill Bridge, I-93 Northbound, Sumner and Callahan Tunnels and overhead item inspection of the I-90 Tunnel. Deteriorated areas of the tunnel were identified using standard deficiency nomenclature with supporting sketches, tables and photos.

Project Highlights

  • Bridge types include prestressed/post-tensioned concrete box beam, steel structures, and cable stays
  • More than 70 tunnel-related task orders
  • Developed the MassDOT Tunnel Inspection Handbook
