Luhr Brothers Inc

Luhr Crosby, LLC operates as a vertically integrated marine‑construction contractor, managing every step from quarry to final placement. By controlling mining, barge transport, and on‑site stone installation, the company can deliver turnkey solutions for both U.S. Army Corps of Engineers projects and private owners. Based at 5311 3rd St, Alexandria, LA 71302, United States, the firm draws on more than nine decades of industry experience and a workforce of over 400 skilled professionals to keep projects moving efficiently.

The business runs its own rock yards in Lafayette and Port Allen, Louisiana, under the Construction Aggregate Supply name, offering more than 20 limestone‑based aggregate products—including rip‑rap, boulders, bedding aggregates, filters, gabion stone and Aglime—in a variety of sizes and grades. Materials can be sourced directly from the affiliated Tower Rock Stone Company quarry, which is approved to produce up to 7 million tons of stone annually, and delivered by Luhr Crosby’s extensive marine fleet of roughly 30 push boats, 400 barges and a range of heavy‑equipment trucks, excavators and bulldozers.

Because the company handles mining, logistics and placement in‑house, clients receive coordinated scheduling, consistent material quality and a single point of contact throughout the construction process. Whether the need is a large‑scale shoreline revet
