History
The Dundrod Circuit in Co Antrim, first used in 1950 for the RAC Tourist Trophy automobile race and the Formula One (non-championship) Ulster Trophy (1950–1953), was Script error: No such module "convert". in length and later amended for the 1965 racing season to Script error: No such module "convert". with the addition of the Lindsay Hairpin. For the 1953 racing season the Clady Circuit was abandoned for motor-cycle racing and the Ulster Grand Prix as part of the FIM Motorcycle Grand Prix World Championship and was moved to the nearby Dundrod Circuit in Co Antrim. The circuit comprised public roads closed for racing including a section of the secondary B38 Hannahstown Road between Glenavy and Hannahstown, Co Antrim, the secondary B101 Leathemstown Road from Leathemstown Corner to Dundrod and the B154 Quarterland/Tornagrough Road from Cochranstown to the road junction of the B38 Upper Springsfield Road/Hannahstown Road at the Lindsay Hairpin. After 1955 cars stopped racing there due to no less than 3 fatalities during the 1955 TT race and safety concerns with the narrow, high-speed nature of the circuit, and since then it has only been used for motorcycle racing.
The photo below shows the original much tighter hairpin, with the modern hairpin, known now as the Lindsay Hairpin, being slightly further back up the road.
