The bridge design comprises a 3-span multi-girder steel/concrete composite deck, simply supported on bank seats. A proven reinforced soil abutment system was required to carry the high vertical loads. The abutment structures needed a certified 120-year life and to address the clients demands for lower carbon solutions
Tensar was engaged by the main contractor, Skanska to look at the bridge abutment design, following successful collaboration on similar schemes. Tensar proposed the TensarTech TW3 wall system for the abutments and wing walls. Working closely with Skanska’s design partner Mott McDonald, Tensar took responsibility for the design of the reinforced soil structures. TensarTech system components were then supplied by Tensar.
