Rehabilitation works on Old Flatts Bridge in Rotherham received a certificate of excellence from the Institution of Civil Engineers (ICE) in the Smeaton Award category for projects greater than 500k/less than £5 million.
Freyssinet supplied and installed bridge bearings on the project, which was recognised for excellence in civil engineering works in the Yorkshire and Humber region. Works were led by Eurovia Contracting North for Rotherham Metropolitan Borough Council, with design by Streetpride.
Refurbishment and repair works started on the bridge in 2014, which carries the A630 Rotherham Gateway to the Sheffield Parkway over railway lines near to junction 33 of the M1.
As a key city route, carrying over 60,000 vehicles a day, careful planning and road management was required. Effective collaboration between all parties meant works were carried out without closure to any of the four lanes and were completed on budget and four weeks ahead of schedule.
Manufacture of the two stainless steel mechanical bearings and 40 elastometric bearings took place at Freyssinet’s Telford factory, while installation was programmed in two phases – the first phase incorporated removal of the existing two fixed pin bearings in the east abutment (one in north deck, one in south deck) and installation of 20 new elastomeric bearings to south deck (10 to east abutment, 10 to west abutment. The second phase incorporated installation of the 20 remaining elastomeric bearings to the north deck.
