The Department of Infrastructure has been working on the TT course.

The road surface in the area of Ramsey Hairpin was beginning to break up.

A DoI spokesman said: ‘Although traffic moves very slowly here, the asphalt at this spot is subject to tremendous forces as slow moving HGVs twist round the corner.

‘The road has been planed out and resurfaced whilst the route was closed for more substantial work back towards Ramsey.’

Meanwhile, there has been an expansion of the roadside drainage system to deal with water coming down the road off the Mountain Mile.

This surface water is hazardous to motorists especially in winter.

A new piped drainage system has been installed at the edge of the carriageway.

Elsewhere the verge has been taken back, the roadside drain cleared.

Similar improvements have been undertaken between the Veranda and Graham’s Memorial.
