Project Breakdown Client: Aone+, Pass & Co UK Ltd, Versco Ltd Location: Tinsley Viaduct, Sheffield Project value: £7.5 million Duration: April 2019 - August 2019 Division and product: Road Barrier Systems: BG800 Gates Project Background The Tinsley Viaduct carries both the M1 in Sheffield and the A631 roads, 1,033 metres over the Don Valley. 100,000 vehicles cross it a day, making it South Yorkshire’s busiest bridge. ​ To ensure it is kept safe to drivers and passengers travelling across or under the bridge or around it, regular inspection and maintenance of the structure and the surfaces is imperative. ​ This project included upgrades and refurbishments to 2.5 miles of safety barrier, footpaths, drainage and road surfaces on the lower deck. Challenges The major challenge in this project was to maintain N2 containment class vehicular protection with a low-deflection characteristic to the lower deck support piers throughout. It also needed to facilitate emergency access and egress of traffic onto the service road between piers in four locations, whilst allowing contra-flow emergency trafficking of the service road if necessary. ​ Product Overview and Installation Four BG800 Gates, through their Highways England accepted ‘W’ beam connection, facilitated a seamless connection into Pass & Co Uk Ltd’s own systems, whilst providing the required deflection characteristics and emergency opening between hinge points.

The BG800 Gates were selected for installation on the lower deck of Tinsley Viaduct mainly because of the system performance characteristics, anchorage options and modular length, which was fabricated to a bespoke fit.

Highway Care application engineers, also provided a bespoke anchorage arrangement that made the gate installation a complete solution.

The innovation and application engineering team also trained the Pass & Co UK Ltd team on the installation and operation BG800 Gates, so if any further BG800 Gates are required on this scheme, or indeed any other projects, creating an efficient, smooth supply and install process.

"We choose to work with Highway Care and will continue the relationship because they are innovative and organised and we look forward to continuing our work with them in the future.
