Roads with the steepest inclines
The title of the steepest street has been quite controversial. Baldwin Street in Dunedin, New Zealand had been recognised as the steepest street in the world – with a gradient of around 34.8%,11 – until 2019, when The Guinness Book of Records instead awarded it to Ffordd Pen Llech Road in Harlech, Wales.
However, the decision to give the title to the Welsh street was appealed by the residents of Baldwin Street. New results showed Baldwin Street indeed had a gradient of 34.8%, while Ffordd Pen Llech only reached 28.6%.10 After the appeal, Baldwin Street was reinstated as the Steepest Street in the World.
