Mountain Road to close for one-way introduction
The mountain section of the Isle of Man TT course is set to close ahead of the introduction of a one-way system for the duration of the event.
The A18 Mountain Road will be closed from Ramsey Hairpin to the Creg-Ny-Baa between 09:30 and 16:30 BST for signage and traffic cones to be put in place.
Once the route reopens it will be one-way, with traffic flow in the direction of the TT course, until 09:30 on 10 June.
Cyclists are banned from using the route, which links the north of the island with Douglas, throughout the period.
First introduced for the centenary of the TT races in 2007, the one-way system is designed to reduce the risk of head-on collisions on open public roads during the two-week event.
The Department of Infrastructure has also confirmed the temporary closure of five green lanes to motor vehicles until 16:00 on 9 June.
Closed green lanes:
U14 Glen Auldyn Back Road, in Lezayre,
U17 Park Llewellyn Road, in Maughold,
U56 Peg Willeys Road, in Marown,
U69 Governor Loch Road, in Michael
U90 Snaefell Mines Road, in Laxey
The Isle of Man Constabulary said other green lanes, greenways, and gates on government land that allowed no legal access to the TT course for motor vehicles would also be "clearly marked" by signage.
The Department of Environment, Food and Agriculture previously said the measures were to prevent damage to the uplands.
