Work will continue on Hillberry Corner tomorrow as preparations continue ahead of this year’s Isle of Man TT festival.
Planing work took place today and the road was closed to vehicles until 4.30pm.
Resurfacing will be undertaken tomorrow and the road will be closed to from 9.30am, with a view to reopening to traffic at 4.30pm.
However, the road may also be closed again from 6.30pm until 10pm if extra time is needed to complete the work.
Work at Hillberry Corner had recently been carried out as part of a highway improvement programme.
However, after talks with TT organisers ACU Events Ltd, the Department of Infrastructure agreed to re-lay a section of the surface.
Trevor Hussey, head of motorsport at the Department of Economic Development, said: ‘The recent work was to a good standard, met all highways standards and enhanced the safety of the road from a general motoring perspective.
‘However, concern was raised by TT officials about a slight dip of about 3 to 4 millimetres on the apex of the bend. We closed the road this week to conduct high-speed tests and although no problems were experienced at 120mph in the wet, there was a concern that in the dry at 160mph the dip may catch a rider out.’
He added: ‘After lengthy consideration and discussion with representatives from the ACU, Department of Infrastructure and the Motorsport Group, the decision was reluctantly taken to resurface this particular section of the highway.
‘Because of the nature of the corner it was decided to re-lay right around the bend in order to minimise the potential risks to riders on the approach and exit, while maintaining the integrity of the road. Patching a short section was considered, but would this would not guarantee an improvement at racing speeds.
‘Obviously the safety of TT competitors and other road users is of paramount importance. The Department of Infrastructure will complete the work within two days in an effort to minimise any disruption and inconvenience and we would like to thank motorists for their patience.’
