A rapid build modular bridge system for large spans and heavy loadings
Available for hire or sale, the Retro Heavy Bridge (RHB) is a pre-engineered modular steel bridge system designed to be delivered to site by road and erected very quickly with little or no on site pre-assembly. Smaller span RHB’s can be built and ready for traffic within hours of arrival on site.
RHB units are pinned and bolted together to form bridges of any length with clear spans of up to 51m carrying one or more lanes of traffic. Standard bridges use multiples of 2.5m wide units. Bespoke widths can also be accommodated.
The Retro Heavy Bridge system is suitable for emergency, temporary and permanent bridges on all types of public and private road, from heavily trafficked motorways and urban dual carriageways to construction site accesses and lightly trafficked rural roads.
RHB units are designed in accordance with the Eurocodes to carry loading defined in many different international standards including Eurocode I - III,
LM1 or LM2; HA and various levels of HB loading to BD37/01; and HS20, HS25 or HL93 loading to AASHTO. Many forms of abnormal load and off-road construction traffic can also be catered for.
The RHB all-steel structure provides a lightweight structural solution making bridge abutments and other substructure works simple and cost effective. The system offers flexibility in the positioning of intermediate piers, with skewed supports easily accommodated.
Epoxy based anti-skid surfacing is factory applied as standard. An additional system can be supplied for environmentally sensitive locations to ensure that longitudinal joints between bridge units are watertight.
Standard holes are provided in the cross members beneath the RHB deck to accommodate ducts up to 110mm in diameter, providing support for telecoms and other essential service diversions.
We offer a full erection and dismantling service to ensure that our bridges are built and taken down quickly to the latest quality, health, safety and environmental standards, providing you with complete peace of mind.
The factory welded structure ensures that RHB decking does do not come loose when trafficked, providing a safe solution and significantly reducing in-use maintenance costs when compared to other modular bridge systems.
The Retro Heavy Bridge represents the latest in modular bridging technology. We are confident that once used, it will become your modular bridge system of choice.
