What is a viaduct?
Quick Answer
A viaduct is a bridge-like structure made of a series of arches, spans, or columns carrying a road or railway across a valley, river, or other obstacle. It is often much longer than a single bridge.
The Full Story
A viaduct is an elevated structure built to carry transportation routes over low ground, water, or urban obstacles. Unlike a single-span bridge, a viaduct usually consists of multiple arches or spans supported by piers. They are common in railways and major road networks because they help maintain a level route through difficult terrain. Historic stone viaducts are found in many European countries, while modern viaducts often use steel and reinforced concrete. These structures can be both engineering feats and architectural landmarks.
