Box Culvert

A box culvert is a reinforced concrete structure used to bypass water under roadways, trails, or embankments. While the real-world versions are often massive and buried under tons of earth, this model highlights the specific architectural features that make them work:

• Twin-Cell Design: Features two rectangular openings (barrels) to handle high-volume water flow while maintaining structural integrity under heavy loads.
• Flared Wingwalls: The angled walls at the entry and exit are designed to transition the flow of water and prevent soil erosion around the structure.
