Mark Broadhurst will never forget working as a young site engineer on a road scheme in Cornwall on 20 March 1985.
'Suddenly, a lorry ploughed through a barrier of cones and rearranged my spine, ' he explains. 'Then the lorry drove away.'
Coming to terms with the knowledge that he would never walk again was one of the biggest challenges of his life.
Broadhurst had been working for Cornwall County Council since 1982. His injuries meant that he had to find different ways to work to suit his abilities and presented a challenge for both him and his employer.
'These days, part of my job is to help architects design environments which are accessible for disabled people, ' he says of the successful relationship that has been achieved. 'It is my engineering training that equips me to do this.'
'I want people to realise how much I can do as an engineer, not what I can't.' he says. 'It is so important that everyone is appreciated for their abilities and not their disabilities.'
