The only dead straight main road out of London runs very close to my house. It was the Roman military road out London and ran for a couple of hundred miles. In Saxon times it was called Watling Street.
That's not the only one. A10 from Shoreditch to Hertfordshire is dead straight and follows the route of Ermine Street, the Roman road from London to York.
Ha, funny - we visited London for a week last autumn and stayed in Kilburn near the old Paddington cemetery, and every time we took the bus into the city I found it strange how straight that road was.
