Volvo assists in Portugal’s largest road tunnel project

Volvo construction equipment is working at the Túnel do Marão project – one of the largest road tunnels in the Iberian Penninsula.

Towering at a height of 1,415 meters above sea level, Portugal’s sixth largest mountain, the Serra do Marão, presents a considerable natural obstacle between the country’s second city Porto located on the coast, and Vila Real near the Spanish border. For many years the difficult terrain has impeded travel between the two cities, as well as access to the interlaying regions. Even since the construction of the IP4 highway in the late 1970s the route remains treacherous, especially in winter, due to its winding course.

Each tunnel is about 5.7km longBut that is all about to change thanks to a new government-funded project to extend the A4 motorway from Porto, which currently stops at Amarante – all the way to Vila Real, taking a route straight through the mountain. The new road, incorporating two parallel tunnels running east to west, will significantly speed up travel time between Porto and Vila Real, reduce the number of road accidents in the area and open up the Douro and Trás-os-Montes regions for further development.

With each tunnel measuring approximately 5.7km in length (almost 12km of tunnel in total), the Túnel do Marão, when completed, will be the largest road tunnel in Portugal – and one of the largest in the Iberian Peninsula (including Spain). Given this immense scale, underground construction specialist, EPOS (Empresa Portuguesa de Obras Subterrâneas), which is already behind some of the most important road and rail tunnels in Portugal, Spain and Algeria, was an easy choice for the tender.

EPOS began work on the twin tunnels in October 2014 and plans to finish the concreting and paving stages of the project by February 2016. Still at the excavation stage, EPOS has currently excavated around 35% of the total length. Integral to the success of the project, the contractor is using 22 Volvo Construction Equipment (Volvo CE) machines, 13 of which were purchased shortly before the project began. Part of a larger 71-strong fleet, provided and serviced by independent dealer Ascendum Portugal, EPOS’s Túnel do Marão contingent, includes four Volvo EW140D wheeled excavators, four L220H wheel loaders, and 14 A40G articulated haulers.

Rocking around the clock

EPOS chose Volvo construction equipment for its high productivity, low fuel consumption and reliability.

“On a project like this, where work continues around the clock, 30 days a month, 100% machine availability is one of our biggest requirements – we cannot risk delay due to unscheduled downtime,” says Dias de Carvalho, EPOS’s general manager of 20 years. “I have relied on Volvo Construction Equipment for decades and the quality of the machines, their ease of maintenance and the service provided by Ascendum Portugal has never let me down.”
