Processes & Services

3S Bridge 

3S Bridge has provided turnkey solutions for traffic management that include the design and construction of flyover structures. Site constraints often demand challenging geometry and composite steel beams are an ideal solution. Designed to international codes like AASHTO LRFD to carry highway loads such as HL93, 3S deliver the entire structural steel package, including bearings and permanent deck formwork.

A trial assembly at the factory ensures a perfect fit when the bridge arrives on site.

BRIDGES OF PEACE PROGRAMME

"The bridges have positively impacted on the quality of life and economic revival of our remote communities."

Dr Omar Rangel

“For the community the bridges are also synonymous with safety. The poor condition of the roads and previous inadequate structures forced them to take unsafe alternative routes. Now they can travel in safety and over shorter distances.”
