The Mountain Road will be one-way again next month when a spectators' lap is held during Manx Grand Prix.
ACU Events Ltd has asked for the route to be one-way from 10am until 11.30am on August 25 when the lap is held.
The speedcontrolled lap of the TT course will see bikers gather at the Grandstand from 8.30am.
The lap itself is due to get underway at 10am - and half of Glencrutchery Road would be closed to effectively make it one-way from the Victoria Road roundabout to St Ninian's crossroads.
