Organisers have announced changes to the schedule for the first day of racing at the Festival of Motorcycling.
Roads will close at midday on Saturday, August 24, two hours earlier than originally planned.
Organisers hope this will allow the full schedule to be completed by 6pm, rather than running later into the evening.
The new timetable will see the 500cc Classic TT race kick things off at 12.45pm, followed by Manx Grand Prix qualifying sessions.
Then at 4.15pm the 1967 Senior TT parade, featuring Giacomo Agostini and John McGuinness, will set off from the Grandstand, followed by the Vintage Motor Cycle Club's parade.
If there are any delays, roads could remain closed until 9pm.
