  • Overview

    In May of 2010, the Eastman Chemical Company opened a state-of-the-art plant dedicated exclusively to the production of Eastman Tritan™ copolyester. The new plant, located at the Company’s Kingsport headquarters, will boost production of the high-demand material commonly used in the manufacture of popular sports and houseware products. Integral to the success of the new production facility is the condition of the existing infrastructure at the Kingston plant – namely the railway bridges which transport both incoming supplies and outgoing products. Eastman Chemical Company chose Modjeski and Masters to evaluate the condition of their vital railroad bridges.

    Modjeski and Masters performed an in-depth field inspection and as-built and existing load capacity ratings of two bridges at the Kingsport plant: The Holston River and Holston Ordnance Works Canal Railroad Bridges. A complete report detailing a summary of the bridge condition, inspection findings, ratings and recommendations augmented with photographs and drawings was provided to the Eastman Chemical Company. The Holston River and Holston Ordnance Works Canal Railroad Bridges each support a single railroad track and are in line with each other, approximately 300 feet apart. Both bridges are open deck, riveted, built-up steel deck plate girder structures also carrying product and utility pipelines across their length. The first bridge consists of four 90-foot long simple spans that cross the south fork of the Holston River. The second bridge consists of one 60-foot long simple span that crosses the Holston Ordnance Works Canal. The substructure is of cast-in-place concrete construction.

    A global company with 10,000 employees and $5 billion sales revenue in 2009, Eastman Chemical Company trusted Modjeski and Masters to help keep bridge railway operations at the plant running smoothly. With our proven portfolio of bridge work and reputation for technical excellence, it’s part of what we do best – we help build and maintain great bridges.
