The engineering behind potholes – and an idea to pay for fixing them
Civil engineer Elizabeth Orchard believes Britain has been looking at the potholes crisis the wrong way – and in this edition of Highways Voices she explains why – and finishes with an interesting idea to fund the solution.
Rather than focusing on political arguments over who is to blame, she explores the engineering behind deteriorating roads, from freeze-thaw cycles and aging infrastructure to the impact of changing weather patterns, utility works and decades of underinvestment.

Drawing on her experience as a Chartered Civil Engineer and founder of consultancy Endelevu, in conversation with Paul Hutton, Mrs Orchard tackles some of the biggest misconceptions surrounding road maintenance. She explains why heavier electric vehicles are not the villain many people assume, why simply resurfacing a road often fails to solve the problem, and why maintenance strategies need to be tailored to local conditions rather than relying on one-size-fits-all solutions.
The discussion also examines the pressures facing local authorities, from shrinking engineering teams to the challenge of maintaining thousands of miles of highway with limited resources. Mrs Orchard argues that rebuilding technical expertise within councils could save money in the long term while creating more resilient highway networks.
Perhaps the most thought-provoking section comes towards the end of the conversation, when she suggests Britain should stop treating roads as a financial liability and start viewing them as valuable assets capable of generating income through the intelligent use of data. She points to examples from Europe where anonymised vehicle and infrastructure data are already helping to fund maintenance and improve network management.
"There are solutions, and there are ways of making money - other people in the rest of the world are already doing it [and] it's time Britain catches up," she explains, arguing that a smarter approach to highway data could transform how roads are maintained for decades to come.
This episode offers a refreshing perspective on one of the UK's most talked-about infrastructure challenges. Rather than simply discussing potholes, it explores the engineering, economics and innovation that could provide lasting answers, making it essential listening for anyone interested in the future of Britain's roads.
