Roads & Bridges

Parkhouse Road Bridge

Parkhouse Road Bridge is located in Ardrossan and carries the A78 Trunk Road across the Glasgow to Largs electrified rail line.

Initially, the Works involved the demolition of the existing concrete bridge deck and brickwork parapets. Thereafter, the new construction comprised a new deck with reinforced concrete parapets and provision for all the existing utility services. The new deck was also re-profiled to improve the clearance envelope for the overhead power lines for the railway below.

Work had to be carried out to ensure, that there was no service interruption of the existing utilities crossing the bridge, that pedestrian access across the bridge was maintained and there was no unplanned interruption to the timetabled rail services below.

A phased demolition and construction programme was adopted whereby 2/3rd of the bridge deck was demolished and reconstructed, with the remaining 1/3rd following thereafter. This sequencing allowed the utility services and pedestrians to be accommodated on one side of the bridge throughout the construction works.

A considerable part of the works was carried out under planned possession and isolation of the railway below.
