The TT Grandstand including the startline, pit lane, re-fuellers, merchandising and scoreboard for the Isle of Man TT and Manx Grand Prix races is situated on the A2 Glencrutchery Road, in the town of Douglas, Isle of Man.
The startline for the 1911 TT races was originally situated on a level section of the A2 Quarterbridge Road between Selborne Drive and Woodlands Lodge in Douglas.
The startline and refuelling area was moved to the top of Bray Hill for the 1914 TT races, and then moved in 1920 to the Nobles Park area of the A2 Glencrutchery Road at the junction of Greenfield Road in Douglas.
For the 1920 TT races, changes were made to the Snaefell Mountain Course and competitors turned left at Cronk-ny-Mona and followed the primary A18 Mountain Road to Governor's Bridge Dip with the new start/finish line nearby on the A2 Glencrutchery Road which lengthened the course to 37¾ miles.
For the 1926 Isle of Man TT races the startline section at Glencrutchery Road was improved by road widening and a new grandstand complex at a cost of £2,000. The wooden structure was demolished and replaced with a modern purpose-built brick design incorporating a wider pit-lane built on newly acquired land for the 1986 TT Races.
The official TT regulations paddock diagram shows many public, technical and administrative areas developed into the Grandstand, including:
