A proven rapid build modular bridge and flyover system
Available for hire or sale, the Retro Over-bridge (ROB) is a pre-fabricated modular steel bridge system combined with pre-engineered intermediate supports and other specifically developed details to deliver a proven solution for inner city flyovers and other multi-span over-bridges.
Standard ROB units are 1.5m wide and can be placed side by side to form any bridge width required: 3m, 4.5m, 6m, 7.5m, 9m, etc.
Pre-assembled for rapid build, suitable for vehicles up to 45 tonnes GVW
The standard span module is 25m. Bridge units are pre-assembled for delivery by road and rapid erection and installation by crane at site.
Completed flyovers and over-bridges are suitable for use by public road going vehicles with a Gross Vehicle Weight of up to 45 tonnes.
The ROB system is designed using established in-house Retro Bridge design procedures to carry the lighter loading categories of many different international standards including HA loading to BD37/01 and HS20 loading to AASHTO.
Safe to use, re-locatable, suitable for temporary and permanent use
ROB units come with factory applied anti-skid surfacing as standard.
Completed over-bridges and flyovers are re-locatable with ease and are suitable for permanent and temporary use, providing much needed congestion relief and road diversion and bridge crossing capability for a variety of different applications.
Retro Over-bridges are ideal for temporary and permanent flyovers and over-bridges on public roads, private estates and construction sites alike.
