Who We Are

Family from day one

KLB Construction was founded in 1984 by Kelly Lynn Bosa, the daughter of a highway construction family, a traffic control flagger, and 25-year-old mother of three. From these humble beginnings, KLB began operations as a women-owned business, providing roadway grading, concrete work, and highway safety improvements—eventually growing into civil construction and transportation projects.

As KLB grew, so did the size, scale, and complexity of our projects. Having nurtured close relationships with a strong network of project partners, general contractors, suppliers, and subcontractors, we were able to tackle these opportunities head on—reinforcing trust, expanding our capabilities, and successfully completing an expanding portfolio of renowned projects throughout the region.

Today, KLB remains a family company, even at 300 employees and counting. We’ve maintained our values and culture by staying true to the principles upon which we were founded: hard work, resilience, family, and respect. Many of us have been with the company for decades, or as second-generation team members, and we’re proud to do our part to further the legacy of KLB.

We’re at our best when faced with a challenge

Honoring our responsibility to do right by our employees, our clients, and the communities we serve, we operate under the strictest standards of safety, proficiency, and fairness in everything we do.
