Boat Christening - M/V Bradley Neil

On Wednesday, November 20th we christened the M/V Bradley Neil at Cape Sandy Quarry.
Brad Mulzer had been a staple at Mulzer Crushed Stone for decades. He loved all the quarries and especially Cape Sandy. That is where he spent so much time and felt at home. Thus, the reason it is so fitting that a switch boat at Cape Sandy be named after Brad.
What made Brad so special was his selflessness. He was the epitome of a servant leader. He knew that the employees made Mulzer Crushed Stone, thanked them for that, and considered them his extended family.
It was a great day christening this fine boat with his full family (Mulzer and extended) in attendance.

Mulzer Crushed Stone Set to Begin Construction on Expansion Project at Cape Sandy Quarry

Tell City, Indiana, August 15, 2024 – Mulzer Crushed Stone, Inc., a CRH company, announced plans to begin construction on a phased expansion project at its largest limestone quarry in Leavenworth, Indiana. The project will modernize two processing plants and construct a new entry road, wash plant, support facilities and river barge loadout system. The multi-year project is scheduled to be completed by the end of 2027.
Once completed, aggregate production operations will be transformed at the company’s flagship location. These improvements will also result in a reduction of carbon emissions annually, reduced process waste and enhanced safety through traffic flow efficiencies.
“This investment represents our commitment to safety, operational excellence and environmental stewardship. The quarry transformation will enable us to provide our valued customers with a wider range of custom aggregate products and solutions across a five-state region. Furthermore, this will strengthen our position as the region’s leading supplier of building materials,” said Ken Mulzer, Jr., President of Mulzer Crushed Stone, Inc.
