Precast concrete stairways completed for Mersey Gateway Project

Clifton Road Bridge upgrade underway

Six new precast concrete stairway units weighing up to 32 tonnes have been manufactured as part of the upgrading of the Clifton Road Bridge between Beechwood and Cholmondeley Road in Runcorn.

The work is part of the the Mersey Gateway Project, a six lane toll bridge across the River Mersey linking Widnes and Runcorn, which commenced on site in May 2014 and is due to open in the Autumn of 2017.

As part of this project, Runcorn based Civils contractor VolkerLaser have been working on 24 structures for the projects Main Contractors, Merseylink Civil Contractors Joint Venture, a consortium comprised of Spanish Contractor FCC Construcción S.A., Kier Infrastructure and Overseas Ltd, England and the Samsung C&T Corporation of Korea.

One of VolkerLaser’s contracts on this project involves the upgrading of the Clifton Road Bridge between Beechwood and Cholmondeley Road in Runcorn.

VolkerLaser appointed PCE Ltd to carry out the removal of the existing six large precast concrete staircase units and supply and install their normally reinforced precast concrete replacements, which were designed by Consulting Engineer URS.

The six new precast concrete units for the the Clifton Road Bridge, weighing up to 32 tonnes, were manufactured by casting  tread down in high quality engineered timber moulds and then turned through 180 degrees before being delivered to site.

Mould manufacture commenced in February 2017, with casting of the new units starting in April.
