The Mountain Road will be shut for much of today - as part of the final preparations for TT.
Signs and equipment for the traditional one-way system is being installed by the Department of Infrastructure.
As a result, the route will shut along its entire length from Ramsey to the Creg ny Baa from 9.30am.
When it reopens at around 4.30pm, it'll be one-way heading south for the rest of the festival.
