It is the longest road in the country, winding 410 miles between the capitals of England and Scotland.
Embarking on a visual tour of the A1 photojournalist Peter Dench wanted to capture the mood of the country as he made his way north from his home city of London.
His aim was to explore the idea of British identity in the wake of Brexit by picturing the characters, sights and locations he passed as he travelled to Edinburgh.
Speaking to MailOnline he said: ‘It was a snapshot from the nation to gauge how people were feeling…it’s called “Britain on the verge”.
Mr Dench’s journey began in St Paul’s where he pictured workers in Panyer Alley, with a red London bus in the background

Mr Dench, who lives in Crouch End, said he wanted to meet the real people of the UK as he journeyed up the longest numbered road in the country.
He told MailOnline: ‘There’s a few reasons I wanted to do this. I am a photojournalist and I’m known for my work on Britishness. Ten years ago I produced a book on alcohol in Britain and I’ve also done one on Brits abroad.
‘Britain is my home country and I wanted to explore the idea of British identity post-Brexit.’
The project was also intended as an homage to Paul Graham who undertook a similar photographic expedition in 1981 and which encouraged Mr Dench to become a photographer when he was a young boy.
He said: ‘I wanted to find out what people expect from Brexit and what the country is going to do…I wanted to see whether they think it’s going to the dogs or whether it can be a success.
‘Generally I found there’s an optimism for the future. British people are very stoic and have a can do attitude. And while people were a little bit worried and uncertain about what was going to happen, they felt we needed to get on with it and make it work.
‘Brexit seems galvanising for people in a way…it’s made them want to work a bit harder to maintain their business and their lives. It’s quite a cleansing time for people, a time for them to take stock.’

It’s the only way to survive’
The A1 starts near St Paul’s in London, passing the Brutalist architecture of the Barbican Complex.

At another point on the Holloway road, Mr Dench met Mark, a 32-year-old fruit and vegetable seller from Essex.
Mark said his business had suffered because of price rises in transportation and import costs as a result of Brexit but remained optimistic his business would survive once things ‘settle down’.

Moving into Scotland Mr Dench met a French couple taking a picture of the ‘Welcome to Scotland’ sign. He also pictured a Indian family on holiday outside a Scotsman newspaper billboard in Edinburgh.
Reflecting on his journey Mr Dench told MailOnline: ‘What I discovered was there isn’t so much a north/south divide as a London/everywhere else divide in Britain.
‘It’s not so much a resentment of London, it’s more a mistrust and envy that all decisions are made in London so people feel removed and detached from what’s happening.’
He added: ‘Driving the length of the A1, Britain doesn’t seem full. At times it feels lonely. But if the stoicism, drive and grit of the people I met is an accurate reflection of the nation, Britain is going to be okay.’
