What is ABC bridge construction?
Accelerated Bridge Construction (ABC): ABC is bridge construction that uses innovative planning, design, materials, and construction methods in a safe and cost-effective manner to reduce the onsite construction time that occurs when building new bridges or replacing and rehabilitating existing bridges.
What are the main techniques used in bridge building?
Described below are the different methods employed in the construction of bridges.
- Cast-in-situ Method of Bridge Construction.
- Balanced Cantilever Method of Bridge Construction.
- Precast Method of Bridge Construction.

How fast can a bridge be built?
A typical low-profile, 300′ long timber vehicular bridge, with custom guide rails, can be completed in under 60 days. Every site is different. Every bridge is different. In general, our process of design, materials procurement and construction can be faster than bridges made with concrete or steel.
How bridge is made in water?
Cofferdam technique is used in this case. In this method, a wall enclosing an area is build inside the water and water is continuously pumped out from the area. After that, foundation of the bridge(the pillars) is constructed inside the cofferdam. As the construction place is sea or river itself.

Did China build a bridge in 43 hours?
A major overpass in Beijing known as the Sanyuan Bridge was demolished and completely replaced in just 43 hours. Unlike China’s other efficient method of building bridges, the 300-foot, 580-ton machine known as the SLJ900/32, this freeway overpass was constructed as a single prefabricated piece and slotted into place.
