Ayesa to design Palma’s second ring road to help city congestion in Majorca

Ayesa will provide comprehensive engineering services for the first section of the ring road with a 110 million euro budget, ensuring the project is ready for the construction phase.

A significant portion of the road will pass through an 820-meter tunnel to minimise the impact on the surrounding landscape.

The Consell de Mallorca, the governing body of Mallorca, has awarded Ayesa, a global leader in technology and engineering services, the contract to design Palma’s second ring road. Ayesa will oversee the development of the construction project for the first section of this major infrastructure initiative, one of the most ambitious projects of the current administration in the Balearic capital.

The project is budgeted at 110 million euros, with construction expected to begin in late 2026 or early 2027.

The joint venture, led by Ayesa (75%) and G-Six (25%), will provide technical services to connect two major motorways on the outskirts of Palma. The project includes traffic simulations for the complex interchanges, tunnel and infrastructure design, risk analysis, and stormwater infrastructure, including rainwater infiltration basins, among other features.

Rainwater infiltration basins are designed to capture and store rainwater, allowing it to seep into the ground gradually. This helps reduce surface runoff, recharge groundwater supplies, and prevent flooding—crucial elements of sustainable stormwater management, particularly in urban environments.

820 metre tunnel

A significant portion of the route will be placed underground to minimise the impact on the landscape. The 820-meter tunnel will begin at Coll d’en Rabassa and end at Camí Fondo, linking the airport motorway with the second ring road at Son Ferriol. The tunnel will include exit ramps that provide access to the surrounding commercial and industrial areas.

Above the tunnel, two roundabouts will be constructed, linked by an avenue with dedicated pedestrian and cycling lanes. A 450-space park-and-ride facility will be located near one of the roundabouts, with shuttle lines providing easy access to Palma’s city centre.

“This contract represents a significant milestone for Ayesa in developing peri-urban tunnels with heavy commuting traffic,” said Sebastián Ribot, Director of Civil Engineering and Architecture at Ayesa.

Ayesa brings extensive experience in tunnel design and construction, employing global best practices and advanced technologies. These include numerical modeling for soil-structure interaction and predictive and monitoring techniques to manage earth movements during tunneling.
