The 11th Milestone, Isle of Man[1] (Drinkwater's Bend)[2] is situated adjacent to the 13th Milestone on the primary A3 Castletown to Ramsey Road which forms the boundary between the parishes of Kirk German and Kirk Michael in the Isle of Man.

During the 1830s, the primary A3 Road Castletown to Ramsey was re-profiled between Cronk-y-Voddy and Handley's Corner by the local parochial highway surveyor under the former Isle of Man parish board system.

The distinctive elongated S-bend corner of the 11th Milestone section of the A3 Castletown to Ramsey road became part of the 37.50 Mile Four Inch Course for the RAC Tourist Trophy automobile races held in the Isle of Man between 1908 and 1922.

[11][12] On the 5th lap of the 1961 Senior TT Races, Ralph Rensen crashed at the 11th Milestone and later died from his injuries.

[13] The corner was subjected to road surface repair work and re-profiling during the winter of 2005/2006 by the Department of Transport.
