Mardyke Bridge, Cork

The North Mall to Mardyke section of the Lee Walk was dedicated by the Lord Mayor, Cllr. Deirdre Clune, on 1st February 2006. The bridge is a single span construction made of steel, stretching some 57 metres in length and having a 3 metre-wide footpath cantilevered from the bottom chord of the arch. Integral to the design is a circular viewing platform built into cantilever retaining walls, adjoining the north bank seat.

The bank seats are of reinforced concrete and have architecturally shaped parapets resting on precast concrete piles, driven 10-15 metres into the ground. The bridge is stiffened by the steel deck top plate which helps control its deflections and dampen its dynamics. The plate prevents the arch member from deflecting too much out of plane. Mardyke bridge was manufactured off site with the finishing touches and assembly done on site, upon which it was lifted into position in a single operation.
