Types of Arch Bridges Explained - Deck, Portal, Through, and Half-Through Designs #3876385 (License: Personal Use)

This diagram illustrates four fundamental arch bridge designs: deck arch (deck above the arch), portal arch (deck supported by vertical struts from the arch), through arch (deck passes through the arch frame), and half-through arch (deck sits midway within the arch). Each configuration offers distinct advantages in terms of clearance, load distribution, and construction complexity, making them suitable for different terrain and traffic requirements.

Used on civil engineering educational pages, infrastructure project documentation, or transportation planning websites to help students, engineers, and planners understand structural typology. Matches user intent to compare bridge designs for academic, professional, or procurement purposes.
