The roads, bridges, and infrastructure we rely on every day were built by generations of skilled workers, many whose names never appeared on blueprints or signs. This Black History Month, we acknowledge the contributions of engineers, laborers, surveyors, and maintenance crews whose work helped shape America’s transportation system and strengthen our communities.
