One way system to be put in place on Mountain Road today
The Mountain Road will be closed until this afternoon while the TT One Way system is put in place.
The A18 can only be used in the direction of the TT course from Ramsey to Douglas during TT fortnight in a bid to reduce the number of serious crashes in the area.
The Department of Infrastructure will close the route at 9.30am.
The road will be open again by 4.30pm, when the one way system will be in operation.
