Arup, Mabey launch Pedesta, a modular glass-fibre polymer bridge

Arup and Mabey have launched what they claim is the first modular glass-fibre reinforced polymer footbridge, with Mabey becoming the first licensed distributor.

The Pedesta bridge comes in any length to suit site requirements
Arup and Mabey have launched what they claim is the first modular glass-fibre reinforced polymer footbridge, with Mabey becoming the first licensed distributor.


Based on a concept by engineering design company 1419 Arup, Mabey debuted the bridge, called Pedesta, at Bridges 2017, a one-day conference and exhibition in the English city of Coventry in March.

The Mabey Group specialises in the design and provision of temporary works including propping and jacking as well as environmental monitoring services, formwork and falsework systems and the hire of non-mechanical groundworks equipment.

The post-tensioned Pedesta bridge can be assembled in remote or hard-to-reach sites inaccessible to large cranes and heavy machinery. Mabey said that the bridge provides a safer alternative to level crossings where traditional pedestrian bridges cannot be installed. Being 70% lighter than steel, the modules require only a pallet truck or forklift for transportation and handling, enabling faster, safer and more efficient project delivery.

The first bridge has been installed at a Site of Special Scientific Interest for Network Rail in Oxford. The bridge modules were light enough to be transported by an articulated truck, assembled on site and then lifted and positioned from a distance.


Pedesta is fully customisable its form, material, colour and finish. The material provides additional resistance to fire, graffiti, vandalism and ultraviolet radiation. It features include 1m-long identical modules fixed together with bolted shear connectors and then post-tensioned. The system allows spans of up to 30m so it can adapt to suit any application.

“We can see this bridge being useful for a whole host of global applications – from rail footbridges to road and river spans,” said Rebecca Stewart, an associate at Arup.

    Taking a road and rail link across one of the biggest rivers in South America, together with its swamps and flood plain, calls for a new crossing of superlative dimensions. Two 135.5m pylons for the third bridge across the Orinoco River in Venezuela are taking shape with the Venezuelan government investing in the showcase project at Caicara del Orinoco. The bridge will have an overall length of 11.125km on completion, which is scheduled for 2015. The main bridge is 2.28km long, and the roadway is 55m above

The safe and efficient flow of traffic through work zones is a major concern to transportation officials, industry, the public, businesses, and commercial motor carriers. This is the view of the US Federal Highway Administration (FHWA), which has developed the Highway Work Zone Safety Program to reduce the fatalities and injurious crashes in work zones, and to enhance traffic oper

    During the past two years, Estonia’s Road Administration has clocked up 4,021km during a retroreflectivity project on all main state roads and on basic roads. Estonia’s Road Traffic Development Department of the Estonian Road Administration has been working with ERC Consulting to gather retroreflectivity data on road markings on all main state roads and basic roads. The work has shown that out of 1,609km of main state roads, 20% had problems. The reflective effect is created by glass beads on the surf
