Entrance Permit

Culverts are an important part of our road system’s drainage infrastructure. Entrance culverts, such as road culverts, help ensure proper drainage alongside our roads by managing water flow through ditches. When roads are properly drained, water is prevented from accumulating in the road base, which helps avoid long-term issues such as pothole formation, cracking, surface irregularities, and general deterioration.
