Mabey Delta™ Bridge

Our Mabey Delta™ Bridges provide a proprietary pre-fabricated modular bridging system suited for long-spanning permanent applications on main highways or in rural areas. It uses standardised, interchangeable steel components with full highway loading capability to provide a permanent, lightweight, steel bridging solution which can be configured for clear spans of up to 90 metres. It can also be supplied in multiple spans, supported on intermediate piers, meaning that there is no limitation to the length it can bridge.

Combining the best of off-site fabrication with high speed construction and rapid installation, our Delta Bridges offer significant advantages over more traditional construction techniques which involve major site work. The versatility and robustness of its design means that it can be easily assembled and dismantled, making it equally suited to long-term temporary bridge applications.

Mabey can supply a solution to suit your particular requirements and we are able to accommodate any special load requirements as well as site specific topography, extremes of temperature, high wind loads, and seismic requirements.
