Galicia: The final section of the Lugo-Santiago motorway

Construction begins on the Melide-Arzúa section of the A-54

On March 20, the first stone was laid as construction begins on the “Melide Sur link- Arzúa Oeste link” section of the A-54 motorway, in the province of A Coruña. These works will meet an expected demand of about 8,000 vehicles/day and are expected to be finalized by 2022.

IDOM has participated in the design of this infrastructure. Its objective is to improve safety, comfort and reduce travel times. Once completed, the motorway with two lanes in each direction will cut the travel time from Lugo to Santiago by 30 minutes. Bypassing the towns and villages, the journey will take an hour.

Together with Arenas y Asociados and Ciesa, our Firm has undertaken the Alignment and Construction Detailed Design of the final stretch of the A-54 highway, which was approved in November 2015.

19 different structures have been designed for this road project, 8 of which are viaducts crossing rivers and streams of varying widths, 99 m to 447 m. The two longest viaducts, crossing the Boente River (447 m) and the Rego Valverde (270 m). Both these viaducts have been executed as a single platform over the entire cross section.

IDOM was present at the event, which was reported on the website of the Ministry of Development. The Minister of Development and the President of the Government of Galicia, were among the dignitaries that attended the event.

Some technical data

The length of the project is 16.38 km, with a section formed by two carriageways of two lanes each, separated by a 9 metre median.

Four links have been designed to connect the motorway with the national highway N-547, the autonomous highways AC-840 and AC-905 and the provincial highway CP-4603.

The earthworks involved excavating over 4 million cubic meters and more than 3.5 million cubic meters of landfills.
