The same sources said that the barriers will not be unsightly at all as they will blend in with the environment - an essential factor as last year, the mountains were declared a World Heritage Site by UNESCO.
The four roads in question will be the access to Sa Calobra; Capdellà to Andratx; Andratx-Estellencs and Calvia to Valldurgent.
The barriers won't form a continuous line as it is just on some sections of the four roads that they will be erected, at points assessed by technical reports to pose the most risk to drivers. For instance on the Sa Calobra road (Ma-2141), the barriers will be erected at intervals only along the stretch between the 5 and 11 kilometre mark. The work on the barrier erection will start at the end of this month or the beginning of February. Department Director Mauricio Rovira said yesterday he wants to see the work finished by Easter and the start of the high tourist season because the roads in question are the most heavily used in the Tramuntana by the visiting population.
