KCI was selected for this project due to our unique solution to the problem of moving a 2,000 foot long bridge!  In order to alleviate congestion and improve the structure to lengthen it’s life, the project includes complete replacement of the ramp from I-44 to the Poplar Street Bridge, removal of the asphalt surface on the PSB and replacing it with concrete paving, structurally tying the eastbound and westbound bridges together, widening the elevated sections of Eastbound I-64 and Route 3 South, and adding 9′-0″ to the PSB width. To complicate the project, this 9′-0″ is added between the EB and WB bridges, accomplished by sliding the entire 2,000 foot long Eastbound bridge at one time to make room for it!
