One-way system being put in place
The Mountain Road between Ramsey and the Creg-ny-Baa is shut between 9.30am and 4.30pm on Friday.
It's to allow for the one-way signage and bollards to be put in place for the TT period.
When the road reopens it will be one-way in the direction of the course - in other words from Ramsey to the Creg.
It will remain this way until Monday, June 13, when a further daytime closure will be in place to remove the one-way restriction.
