The A1 was re-routed in 1967 following the opening of the Tyne Tunnel but the most northerly section of Northumberland Street remained open to traffic in until 1999 and was a busy bus route. Today Northumberland Street is completely pedestrianised with access only granted to emergency services and delivery vehicles at certain times.
Today Grey Street is known as being one of the best streets in Great Britain (it was voted number one by BBC Radio 4 listeners in 2010) due to its fabulous display of Georgian architecture. Whilst the buildings have remained largely untouched, it is interesting to see how the street has developed over the years. The changes in clothes and cars are particularly striking!
