The Principality of Asturias' Department of Infrastructure, Land Policy and Housing has awarded an FCC joint venture the contract to twin road AS-17 from Avilés to Puerto de Tarna, Asturias. The contract is worth 34.6 million euro, and the completion period is 27 months.

The plan is to take advantage of the existing road to twin the 4.7 kilometre-long section for its eventual conversion into a dual carriageway. The job includes the construction of nine structures.
