Bridge Construction


Across the country, for decades, the team at Kolb Grading has been building bridges across a wide range of terrains. Understanding the unique needs of each build, the latest construction methodologies and the impact on local environments are all aspects the Kolb Grading team factor into our planning to ensure that the bridges we build stand the test of time.

Our experience in all aspects of road and infrastructure engineering, combined with our bridge construction experience, makes many large highway and infrastructure projects seamless. As a family-owned company, we believe the best projects start and end with safety for all members of our team. Safety is more than an Experience Modification Rate (EMR) number; it’s a culture we are committed to.
