Sibley Pond Bridge Replacement

Canaan-Pittsfield, ME

UPDATED NOVEMBER 2011—Bridge Open to Public 10-1/2 Months Ahead of Schedule
The 10 span 790 ft long Sibley Pond Bridge with integral abutments and with only one expansion joint in the middle of the bridge was opened to traffic on November 21, 2011; before winter and approximately 10-1/2 months ahead of the MaineDOT’s scheduled project completion of October 2012. The bridge was designed and completed in 15 months.

The selection by the Lane Construction Corporation/Parsons Brinckerhoff Design-Build Team of the NEXT D beam (New England Extreme Tee) with its integral precast deck enabled the bridge to be erected very rapidly due to maximizing precast and limiting cast-in-place field concrete construction to continuity placements at the pier diaphragms and longitudinal joints between the beams. The project is the first to use the PCI New England NEXT D double T beam section and that too with self-consolidating concrete. The beams were cast by J.P. Carrara & Sons, Inc. at their Middlebury VT plant.

The beams were erected using a gantry crane running transversely on rails from the partly demolished existing bridge and across the new piers while Rt. 2 traffic was using a 2-lane temporary detour.
