Prefabricated Steel Bridges Provide a Safe and Cost Effective Solution for ABC
Accelerated Bridge Construction (ABC) is bridge construction that uses design and construction methods to reduce the onsite construction time and mobility impacts that occur when building new bridges or replacing and rehabilitating existing bridges.
- Steel bridges can be fabricated off-site in a controlled equipment and ready to erect as soon as it reaches the bridge site.
- Reinforcement and formwork installation is not required. Steel erection is not limited to a specific temperature range.
- Steel is often lighter than other materials for the same span, resulting in smaller or fewer erection cranes.
- Prefabricated steel bridges accelerate construction and reduce on-site labor requirements, reduce traffic disruption, and overall project costs. They are also safe – reducing the exposure of workers and public to construction activities as well as environmental impacts.
