About this event

The £10 million, 52-metre span, Leigh Road Bridge in the heart of the Slough Trading Estate was designed as a major new infrastructure link across the Great Western Railway to significantly improve transport movement for the business population of the trading estate and the wider community.

The original bridge concept evolved from the PBA transport strategy developed in 2006 to support SEGRO's vision to regenerate the central core of the estate and stimulate economic growth through the attraction of new tenants and retention of existing occupiers on the estate. The bridge was principally aimed at improving accessibility and road safety in preference to a narrow contra-flow road bridge that now sits alongside the new bridge as a converted pedestrian and cycle link. Comprehensive environmental and transport assessment was produced by PBA to successfully deliver the proposals through planning with multiple authorities and stakeholders.

The conceptual, AiP and detailed design was engineered by PBA on behalf of the contractor, Osborne, and successfully gained agreement with Network Rail and Slough Borough Council following an independent consultant's analytical check.

One of the key challenges was to install the bridge in a narrow window to minimise disruption on the GWR and the busy services in and out of London Paddington. PBA advised the client on a number of installation options including crane, before it was agreed to launch the assembled structure over the railway during a night time rail possession using Self Propelled Modular Transporters (SPMTs).

The bridge was officially opened in 2015 and was Highly Commended in South East England's 2016 Engineering Excellence Awards.
