Overpass vs. Bridge — What's the Difference?
By Tayyaba Rehman — Updated on October 20, 2023
An overpass is a raised structure allowing passage over an obstacle like a road, while a bridge spans over obstacles such as water, valleys, or roads.

Key Differences
Overpasses are specific infrastructural elements designed primarily to facilitate the uninterrupted flow of traffic over obstacles, most commonly roads or railways. Bridges, while similar in foundational concept, have a broader application, spanning over bodies of water, valleys, and other terrains in addition to roads.
An overpass is usually associated with urban or suburban settings, ensuring that roadways or railways cross without interfering with each other. Conversely, bridges are ubiquitous, found in both urban landscapes and rural settings, serving both pedestrian and vehicular traffic.
The primary function of an overpass is to eliminate intersections and enhance the flow of traffic. Bridges, on the other hand, can be symbolic, historical, and even aesthetic landmarks beyond their practical use.
In terms of design and engineering, overpasses may primarily focus on functionality and safety for traffic above and below. Bridges often incorporate architectural considerations, especially in iconic structures that define city skylines or scenic views.
