Dr Geoffrey Clements discusses the importance of developing world-class highway networks for nations' economic prosperity and transportation infrastructure. Major highway projects now involve international collaboration between public and private sectors, requiring highway managers to have multidisciplinary expertise in areas like strategic planning, design, management, engineering, and stakeholder engagement. The Commonwealth Infrastructure Partners organization has over 30 years of experience in highways and bridges projects across many necessary areas of expertise, and can provide training to help develop these skills in the sector.
