Signpost Corner, Road curve on Snaefell Mountain Course, Isle of Man
The curve features directional signposts at the intersection of A18 Snaefell Mountain Road and A39 Hillberry Road in Onchan parish.
The corner served as a signal station for Isle of Man TT races, connecting to Glencrutchery Road scoreboards through telephone lines operated by race officials.
Author George MacDonald Fraser referenced this location in his 2002 memoir titled 'The Light's On at Signpost', connecting literature with racing heritage.
The road section underwent modifications in 1953, with widening and reprofiling work between Signpost Corner and Bedstead Corner to enhance racing conditions.
Local Scouts managed a light signal system at the corner, indicating to pit crews and officials when specific competitors passed through this racing checkpoint.
