Work on the new I-64 Kanawha River Bridge (Figs. 1, 2 and 3) in South Charleston, West Virginia continues to go well. VSL is working closely with the General Contractor, Brayman Construction Company, to supply the post-tensioning systems for the cast-in-place concrete bridge. In addition to furnishing over 130,000 lbs. of post-tensioning bars manufactured by Dyson, VSL is also providing approximately 1,085 tons of 0.6" diameter post-tensioning steel. To meet the enhanced durability requirements of the project, VSL's PT-PLUS™ plastic duct system is being used. Along the 1-3/8" P-T bar being used, the tendons sizes are 6-31, 6-22, 6-19, 6-12 & 6-4.
