Breckenridge Material has deployed a portable plant to supply 60,000 yd. of conventional and high performance mixes for the Interstate 64/Daniel Boone Bridge expansion. Under a lease arrangement, the equipment is running adjacent to the Lafarge St. Louis Sand Operations, Chesterfield Dock offload—less than 1,500 ft. from most pours.
The three-year, $125 million Missouri of Department of Transportation project calls for construction of a new 510-ft. structure carrying eastbound traffic over the Missouri River; upgrade of a 1980s steel trestle bridge (left, above) for westbound traffic; and, demolition of the original 1935 trestle (right).
The Breckenridge technical team is developing special concrete mixes to meet MoDOT’s goal of constructing a bridge that will provide more than a century of useful life. They are continuing to work with the project engineer Burns & McDonnell and agency staff to refine and optimize these mixes in order to achieve the life cycle and durability requirements. In advance of producing high performance mixes for the bridge and approach pavements, Breckenridge Material is pouring more standard concrete for 42 drilled shaft footings, up to 8-ft. in diameter and 100-ft. deep.
The Boone Bridge expansion is scheduled for completion in late 2015. Lead contractor is a joint venture of Alberici Corp., St. Louis, and Walsh Construction, Chicago.
