Organisers say paying customers on the TT Grandstand will still be able to see the historic scoreboards despite a safety fence being placed in front.
A risk assessment has concluded that a mesh barrier needs to be put in place to protect scots working on Glencrutchery Road.
Bike speeds are reaching around 180mph past the Grandstand.
Isle of Man TT Clerk of the Course Gary Thompson says safety is always the priority but feels the fans experience won't suffer as a result:
