Aberdeen City Council – Robroy Bridge, A93 Peterculter

Robroy Bridge was a 15m long and 12m high arch bridge with a 4.5m wide extension built against the north spandrel wall to give more carriageway room and allow for a footway to be incorporated, our aim was to remove the entire concrete extension from road level down to water course level, a significant temporary works had to be designed to allow for the removal process.
400m3 of mass concrete was poured into the new abutments, Installation of 8 new prestressed beams and new deck slab cast, parapet installed on the new edge beam and surfacing works.
