Since 1941, Bryan Rock Inc. has been providing quality crushed limestone and limestone rock products for contractors, government, asphalt production, and ready-mix concrete operations through our Minnesota limestone quarries. Our Hwy 41 quarry in Shakopee, Minnesota, is proud to be the leading producer of ball diamond aggregate locally and nationally. Both our Hwy 169 and Hwy 41 quarries in Shakopee produce our unique 'Bryan Red' rock. Our Bayport location in Stillwater, Minnesota, is where we produce our 'Bayport Buff' rock. What makes our product so unique? The finely crushed dolomitic limestone, mined in our Shakopee MN quarries, has a unique red color and the ability to endure the rain. Once this red ball diamond aggregate is spread properly on ball diamond surfaces, shot put areas and trails, it provides years of service with minimal maintenance required. Bryan Rock Inc. is also a leading provider of crushed limestone product for landscaping.
