The original Gobbins coastal path was opened in 1901 but fell into disrepair and was closed in 1951. This reconstruction project consisted of a series of 23 footbridges and cantilevered walkways forming a 1km-long pathway at the base of 60m-high cliffs spanning between rock outcrops and sea stacks along the Antrim Coast. The pathway follows the original route and the iconic bridges have been reconstructed to closely match the original Victorian structures with original steps and walkways retained.
ByrneLooby acted the geotechnical designer for the bridges, cantilever anchorage systems and cable stayed anchors for the main contractor, McLaughlin & Harvey Ltd. We also carried out rockfall assessments and site investigations and developed value engineered solutions along the coastal pathway route to mitigate against unstable sections of the cliff face. We developed a rockfall management plan to assist in managing operational rockfall risks, through a systematic process of geological inspections, continual monitoring and intermittent tactile assessments.
