The Olleria II tunnel was built to pass through the Valencian Sierra Grossa located on the Canals - Agullent highway. This is a road with a high traffic flow due to the great industrial activity existing in the regions of La Costera and Valle de Albaida.
The tunnel is provided with public address and voice evacuation systems made by LDA Audio Tech.
