From the beginning, slipforming bridge parapet (bridge walls) has been at the core of our business, and today that is no different. To date, we have slipformed more than 1.5 million linear feet of bridge parapet on more than 2,450 bridges across several states. We have the capability to slipform various profiles of bridge parapet, including retrofit bridge parapet on bridge rehabilitation projects. We have also been fortunate enough to be a part of several major bridge projects spanning the Mississippi River, Missouri River, White River, Arkansas River, Red River, Ouachita River, and Canadian River. Our bridge crews are very mobile and are always looking for ways to become more versatile to better serve our customers.
