Hugh Carey Tunnel Superstorm Sandy Restoration and Mitigation


Manhattan/Brooklyn, New York<br style='line-height:2px'>MTA Bridges and Tunnels

The Hugh L. Carey Tunnel crosses under the East River, connecting Manhattan and Brooklyn via 18,235-foot-long twin tubes, making it the longest continuous underwater vehicular tunnel in North America. As part of its long-term plan to cope with extreme weather conditions, and to guarantee a reliable transportation system, MTA Bridges and Tunnels initiated the Superstorm Sandy Restoration and Mitigation and Rehabilitation of the Hugh L. Carey Tunnel and Brooklyn Plaza.

HAKS is providing construction management services for this massive $350 million, six-year restoration and rehabilitation project. Our services include preconstruction (constructability and biddability review); construction administration, inspection, testing and specialty CPM services; independent confirmatory inspections and testing; and post-construction, including project close-out. HAKS will ensure that critical systems such as ventilation, communications, traffic, lighting, fire and drainage are maintained and provide construction oversight, including MPT, to ensure safe and uninterrupted tunnel operations for the duration of the project.

Key project features include:

  • Repairs to the concrete liner and roadway ceiling slab and air ducts
  • Replacement of tunnel finishes, low-tension duct bank, lighting, E-box, traffic control, communication, CCTV, fiber optics and fire line
  • Rehabilitation/replacement of the cathodic protection and pumping systems
  • Temporary construction to ensure uninterrupted tunnel operations during construction
  • Plaza rehabilitation, including structural slabs and subsurface, expansion joints, curbs, gutters and restoration of the plaza roadway
  • Lead and asbestos abatement
  • Maintenance and protection of traffic 

Challenges include minimizing tunnel and/or lane closings in this heavily trafficked area and giving motorists advance notice of such changes.
