A study on the economic impact of the introduction of tolls on the Via do Infante will be released shortly. It has been funded by the Junta de Andalucia, the government of the neighbouring Spanish region, and complied by respected journalist Carlos Castellanos.
A study has been promised by the Portuguese government since the tolls were unilaterally imposed on the Algarve region in 2011 yet interested and affected parties wait in vain for this promise to be carried out.
