3S Bridge can also provide a complete package for the design and supply of steel girder bridges, either for replacement or new construction. Steel girders can be installed quickly by a launch method without the need for heavy cranes or often difficult to install and expensive temporary supports.
Locally supplied concrete is used to complete the composite structure. Here again, 3S Bridge includes the permanent formwork, all the bolts, bearings and parapet railing. 3S can also supply the street lighting and expansion joints. All the girder bridges are designed to international codes and fabricated from high strength steel.
The three-span bridge shown below was built in 12 months, including all foundations and substructure.

Bolt-on Services
“We would fully recommend 3S Bridge, LLC to any potential client and have no hesitation in working with them in the future.”
“We are pleased to confirm that in all areas above 3S Bridge met or exceeded the specifications and work order”
Simon Daniel
Deputy Permanent Secretary – St. Lucia
“3S Bridge, LLC of the United States supplied the steel structure, and we can confirm that they supplied the bridge in Full compliance”
“The complexity of the superstructure would also prove to be particularly challenging to assemble and install. 3S Bridge’s site support during the preassembly phase was valuable to ensure the correct profile was achieved”

BRIDGES OF PEACE PROGRAMME
"The bridges have positively impacted on the quality of life and economic revival of our remote communities."
Dr Omar Rangel
Development - Bolivar State, Colombia
“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.”
