Signpost Corner, Isle of Man is a road junction situated between the 36th Milestone and 37th Milestone road-side markers on the Snaefell Mountain Course on the primary A18 Bemahague Road and the secondary B11 Avondale Road in the parish of Onchan in the Isle of Man.
The name derives from a signal station for the Isle of Man TT races and Manx Grand Prix. The signal station at Signpost Corner was connected to the TT Race Scoreboards in Glencrutchery Road in Douglas by a telephone land-line. Officials on TT Scoreboards will switch on a light above a riders individual scoreboard which will indicate to pit-crew and race-officials that a particular rider has passed Signpost Corner and may be shortly pulling into the TT Grandstand to refuel.
The corner was widened during the winter of 1953/54 and the road re-profiled. In recent years the signal station has been moved to a preceding position on the course at Cronk-ny-Mona as race speeds have increased.
