FIRST PLACE UNDERGROUND PROVIDING THE MISSING CULVERT sections measuring 26 feet by 6 feet by 10 feet and 26 feet by 6 feet by 5 feet, each weighing up to 68,000 pounds, were precast. The road was not closed to traffic until the precast Project Use: Box Culvert Project Location: Henderson, Kentucky The Henderson County Road Department recently installed a precast concrete double three-sided 26-by-6foot box culvert on Mason Landing Road in rural Henderson County. When assembled, the double threesided precast structure provided a four-sided box culvert with a finished clear opening of 26 feet by 12 feet. Hydraulically, structurally and aesthetically, this was an enormous improvement from the failed twin corrugated metal pipe structure that it replaced. The precast structure provides the missing link between smaller precast four-sided box culverts, traditional three-sided box culverts with cast-in-place footers, and built-in-place bridges. A combination of units were ready. The structure was placed and the road was available to traffic in two days — a fraction of the time that would have been required for a typical threesided installation with cast-in-place footers and even more so for a built-in-place bridge. A built-in-place bridge would have required a road closure of 60 to 90 days. The vertical joints of the top and bottom sections were staggered by using a combination of 10 feet and 5 feet section lengths. Heavy steel plates were then bolted across these joints to ensure stability of the three-way joints. Additionally, 1-inch-diameter steel tie bars were installed across the joints to provide an additional safety factor. COMPANY PROFILE: Sherman-Dixie Concrete Industries Inc.
