196th Bridge Design and Construction Administration*

196th Bridge Design & Construction Management
City of Kent

TranTech staff, David Belling and Bill Barton provided Construction Administration Management, Inspection and Material Testing for this project respectively. This 1,400-foot long x 69-foot wide bridge passes over Western Processing (a Superfund site), spans Mill Creek as well as several railroad tracks (UPRR and BNRR) and crosses over one Weyerhauser Building.

Several types of foundations and superstructure types were investigated to satisfy the requirements to build a bridge in a Superfund site as well as obstructions as noted above. One of the challenges was to determine a footing type that, during its installation, would not cause the existing buildups to settle or crack. This was achieved with 8-foot diameter x 80-foot deep oscillated drilled shafts.

The superstructure of this bridge is seismically isolated from its substructure via rubber bearings with lead cores.
