More than £360,000 was spent on preparing and managing the Mountain Course for this year’s TT.

Figures were revealed in a Freedom of Information request to the Department of Infrastructure.

The department was asked for the costs of repairing and resurfacing the TT course ahead of TT2017, and the costs of making the mountain section one-way including signs and putting up cones.

In its reply, it said that resurfacing work carried out on the course was identified as part of its maintenance schedule and not at the request of the race organisers.

But it said that three areas were resurfaced ahead of the races - Alpine Corner at a cost of £21,250, Sulby Straight at a cost of £70,000 and Bungalow at a cost of £175,000.

The cost of erecting signage during preparation works and the replacement of any damaged signs was £3,734.

And the cost of removing and replacing cones - including set-up and dismantling - was £86,579.

Finally, the cost of staffing the access road was £7,222, making the total cost for TT preparations £363,785.

The one-way system on the Mountain Road, between Ramsey Hairpin and Creg-ny-Baa, was first introduced for the centenary TT in 2007 with the aim of improving public safety and reducing the likelihood of head-on collisions.

Police dealt with several reports of vehicles travelling against the one-way system on the Mountain Road during this year’s TT.

But the road remains two-way for the Festival of Motorcycling. Cyclists, however, are banned from the Mountain Road for the duration of the festival with the DoI saying this is about ensuring the safety of all road users.
