Ballaugh Bridge,, is a hump-backed road bridge over a stream situated between the 17th and 18th Milestone road-side markers on the Snaefell Mountain Course in Ballaugh village, on the primary A3 Castletown-to-Ramsey road and adjacent side junctions with the A10 Ballaugh-to-Ramsey coast road and the tertiary C37 Ballaugh Glen Road in the parish of Ballaugh in the Isle of Man.
Ballaugh Bridge was part of the Highland Course and Four Inch Course used for the Gordon Bennett Trial and Tourist Trophy car races held between 1904 and 1922. It was the western edge of the Sandygate Loop for the 1904 Gordon Bennett British Eliminating Trial and the 1905 Tourist Trophy Race for cars. The 1906 Tourist Trophy Race used the Short Highroads Course, with the abandonment of the Sandygate Loop in favour of the A3 Castletown to Ramsey Road. Ballaugh Bridge is part of the Snaefell Mountain Course used since 1911 for the Isle of Man TT and from 1923 for the Manx Grand Prix races.
