Founded in 1906, the Brannan Sand & Gravel Company has played an integral role in the growth and development of Colorado’s Front Range. Originally a sand and gravel supplier, it wasn’t until 1943 that asphalt was introduced to support the anticipated post-war building boom. Now, over a century later, Brannan is the front runner in the manufacturing and placement of Hot Mix Asphalt. Diversification has been no stranger to the growth of Brannan. In 1995 Brannan unveiled its Ready Mix Concrete Division to support the increasing demand of rigid pavement. Not far behind, 2003 ushered in the formation of the Brannan Construction Company, specializing in pipeline and tunneling operations. This newest division has allowed Brannan to extend its construction expertise throughout the industry. Today, the Brannan Family of Companies commands a unique position in the asphalt, concrete and aggregate marketplace by providing a wide range of aggregated, asphalt paving and maintenance services, ready mix concrete and specialized construction services. While the face of the Brannan Sand and Gravel Company has changed, the Brannan philosophy remains, just the way J.W. Brannan intended. He was committed to the needs of his customers, providing solutions and then delivering not only superior products but superior customer service. With these cornerstones in place Brannan's vision is the same: to continue to be a nationally recognized leader in the industries we serve. Smoooooth, you BET Brannan did it!
