Little Bay Bridge Project Update

Currently the majority of Phase 1 construction is complete, which includes:
  • Pedestrian bridge to the General Sullivan Bridge (two drilled shaft foundations with “s” curve steel girders and concrete deck).
  • All sub structure drilled shafts (24 each at 8.5 foot diameter with 20+ foot rock socket)
  • All eight phase 1 piers are complete.  A single pier complete phase 1 and 2 has three shafts 8.5 foot diameter which taper into 6.5 foot diameter columns. The three columns are connected by a concrete strut and brought together at the top with a concrete cap. Phase 1 comprises of two of the columns and one strut and a cap connecting and completing the phase 1 pier.
  • Four of the phase 2 piers are complete, four more to go.
  • All structural steel is in place for phase 1.  The center span -- 220 feet of the 1,640 foot span -- was erected on a barge off site and was brought in during a short slack tide window to be strand-jacked in place. An exciting operation!!
  • All precast deck planks were installed, followed by the deck rebar. The 1,640 foot deck was placed in two placement days. 
  • Crews are now working to remove the temporary work trestle back to land as we complete the piers at each location. The trestle has been a key component for access during the construction of the new bridge which spans Little Bay and lies between the General Sullivan Bridge and the existing bridge. 
  • Earth work continues on the main line approach.  This includes building the highway, drainage, electrical, and fine grading.
  • The phase 2 steel will start as the phase 2 piers finish in mid-November. 
  • The steel will all be set from the new phase 1 deck, using two 250 ton truck cranes. 
  • Following the steel will be utilities, deck planks, rebar, then concrete on the deck.
  • The project is well on track to be complete before the completion deadline of April 2014. 
Most important of all, the Little Bay Bridge Team has worked well over 500 days without a safety related incident/injury. Cianbro's client is very happy with the company's quality and progress.  Even though on paper it’s a contractor / client relationship, it really is more than that.  It’s a partnership – it’s pure team work.
