He added: “I am immensely proud of what we have achieved together over the last five years – delivering safer, greener, more reliable roads; strengthening our relationships with partners; and modernising the organisation for the future.”Harris was appointed as chief executive in February 2021, having previously served as executive director of operations since 2016. Under his leadership, National Highways secured development consent for the £9bn Lower Thames Crossing and launched a new Safety Strategy.
