Welcome to ULMA´s web site

ULMA Construcción has contributed to the infrastructure improvement in the Basque Country through the construction of the Eskoriatza North-Arrasate North stretch, which is part of the Eibar-Vitoria Highway. Several projects have been completed within this stretch, such as the Izurieta-Apotzaga tunnel covering 260 meters, which opens out onto the Basagoiti viaduct, of 427 meters, designed to save the existing river bed. Additionally, there are two overpasses that allow overcoming the complex orography.

The bridge over the Skawa River, with a length of 242.95 m, is one of the essential structures of the Zembrzyce road bypass. The structure design aimed at respecting and adapting to the mountainous landscape.

The Second Road Bypass of San Sebastián, connected to the Urumea and to the N-1 highways, decongests the road access to the city and provides alternatives for local and long distance traffic through the region.

The new access roads to the Dos Valires Tunnel are part of one of the largest infrastructure projects carried out in Andorra. They connect the towns of Encamp and La Massana through a complex orography reducing travel times.
