Farm Lane - Marsh Creek pony truss

Back to Project:

DNREC - Farm Lane: With final engineering plans submitted, and with our notice to proceed in hand, the King Bridge Co., Marsh Creek pony truss fabrication began in earnest last week at BACH Steel. Under the careful hands of Nels Raynor, the unloading the truck finished on a beautiful Fall day in Holt, Michigan. The crew then began disassembly of the four trusses into all of their parts and documenting the process continued.

The cool part is that the crew decided to bring back the deck from Pennsylvania too, as we had room on the truck. The decking would make great surfaces to work on they thought, and here you can see them at work. Part of the repairs were to eye-bars and diagonal rod that had to be cut during disassembly. While all care goes into taking our time with disassembly, sometimes parts won't come apart. In this case it was the turnbuckle on both trusses that just wouldn't come apart. Those repairs have been made. We also left one floor beam behind as it was in bad shape, and the new design widening the bridge allows some latitude for fabrication with the material we were able to reuse. The floor beams will still be part of the design with the pins and trusses but connected to larger stringers that allow vehicular loading required in the new location. Soon it will be shipped to Battle Creek / Springfield to Beech and Rich for painting. 

Bach Steel work included: cutting and preparing floor beams, pad welding and repair of diagonal rods and eye-bars.
