Concrete bridges have been built in North America since 1889, when a single arch concrete bridge spanning 20 ft was built in California. In 2019, over 400,000 concrete bridges were documented in the National Bridge Inventory.
Concrete bridges have many advantages including:
Concrete Bridges can be formed to match the environment and have been used for large and small spans.
Concrete bridges have proven to be resilient against all types of loads and impact.
> Structural Redundancy
Concrete bridges form redundant load paths, leading to reliable structural performance.
> Long Term Durability
Concrete bridges have proven to be durable, even in harsh environments.
> Low Maintenance
Concrete bridges require little maintenance.
> Rapid Construction
Concrete bridges may be rapidly constructed using local labor.
Concrete bridges prove to be economical in initial cost and over the long term.
Concrete bridges may be formed using a variety of methods and can meet the demands of any load rating or design features.
Concrete bridges may include many aesthetic features such as color, shape, texture, design or patents.
Concrete bridges may be used anywhere a crossing is required. They may be reinforced, prestressed, precast, post-tensioned, segmental or cast-in-place to meet the design requirements.
Concrete bridges are rapidly constructed using a variety of construction techniques.
