Low-Water Crossings
What is a viaduct primarily used for?
Crossing wide gaps without central support
Spanning valleys or low-lying areas with multiple spans
Supporting substantial loads with a keystone
Being submerged during floods
How do truss bridges distribute forces?
Through a network of smaller structural elements
By using large main cables that hang down
