End of an era as Isle of Man highways leader retires after nearly four decades

After more than 37 years shaping some of the Isle of Man’s most significant infrastructure projects, highways chief Aidan McCusker has retired—bringing an end to a remarkable public service career.

Tributes have poured in from the Department of Infrastructure, recognising McCusker’s lasting impact as Head of Design in Highway Services and his role in delivering key civil engineering works across the island.

Joining the civil service in 1988, he brought valuable engineering experience from Ireland and quickly established himself in building control—overseeing major developments and navigating complex challenges around safety, ground conditions and compliance.

His move into highways in 1990 marked the start of a long and influential chapter. Rising through the ranks to Design Team Leader and later Head of Design, McCusker played a central role in projects that helped shape the island’s infrastructure—from strengthening bridges and coastal defences to upgrading critical retaining walls.

Under his leadership, the Design Section grew significantly, expanding its reach to support projects across multiple government departments.

Reflecting on his career, McCusker said he would miss the people he worked with most, adding he was “proud of the achievements made as part of various teams over the years.”

Infrastructure Minister Tim Crookall praised his “technical expertise, leadership and commitment,” crediting him with helping to deliver many of the island’s most important engineering schemes.

As he steps away after nearly four decades, McCusker leaves behind a legacy embedded in the very fabric of the Isle of Man’s infrastructure.
