Who is Brannan?
Brannan Sand and Gravel has a rich and colorful history dating back to the turn of the 20th century. An ambitious young man named John W. Brannan discovered a sand and gravel deposit at the turntable at 48th & Brighton Blvd in Denver. Using his savvy business skills and a small amount of money, he purchased a mule and a wagon, and the J.W. Brannan Sand and Gravel Company opened its doors in 1906. The J.W. Brannan Sand and Gravel Company furnished material for many of the early construction projects in Denver, including the Denver Auditorium, now the Temple Buell Theater. In 1943, the asphalt division was added to support the anticipated post-war building boom and in 1995 the Ready Mix concrete division was added to support the rising demand for rigid pavement. Brannan Sand & Gravel wasn’t done yet. In 2003 a new division, Brannan Construction Company was formed to support the need for pipeline and underground utilities construction and repair. In 2018 Brannan Sand & Gravel grew again through the purchase of Ready Mixed Concrete Company, bringing their concrete division to a solid place in the market.
Today, the Brannan Companies command a unique position in the marketplace by providing a wide range of aggregate and asphalt materials, asphalt paving, Ready Mix concrete, and specialized construction services. We look forward to working with you and invite you to reach out and let us know how we can help make your project a success.
