Breckenridge Material Co., a St. Louis-based supplier of ready mix concrete, has begun the initial pouring of concrete for the Daniel Boone Bridge expansion. During the three-year project, Breckenridge estimates pouring more than 60,000 cubic yards of concrete for the 510-foot-bridge expansion.

The Breckenridge team of engineers developed and formulated the special concrete mixes to meet Missouri Department of Transportation’s (MoDOT) project goal of constructing a bridge that will provide more than a century of useful life. Breckenridge’s engineers are continuing to work with the design team to refine and optimize these mixes in order to achieve the life cycle and durability requirements. The concrete bridge is expected to endure MoDOT’s projected 50,000 additional daily commuters over a span of 20 years, bringing traffic projections to 150,000 cars daily.

“We are delighted to participate in such a significant and important project to our area,” said Nathan McKean, CEO and president of Breckenridge Material Co. “The new Daniel Boone Bridge expansion brings a much needed relief to commuters traveling to or from St. Charles and St. Louis counties.”

Breckenridge is currently pouring the first set of drilled shafts for this project. During the next few months, Breckenridge plans to pour additional concrete for a total of 42 drilled shafts which provide the footing for the bridge piers, and the next stage of concrete pours.  The shafts will reach down to the bedrock (up to 100 feet deep) and are approximately eight feet in diameter.

The Boone Bridge expansion is expected to be completed by the end of 2015. The Daniel Boone expansion project is a joint venture comprised of Alberici Corp. and Walsh Construction, and designed by Burns & McDonnell.
