ACS is awarded a mega contract of 3,000 million in the US


ACS continues to grow its order book in its main market, North America. The construction and services group, through its subsidiaries Dragados USA and Flatiron (Hochtief), and in UTE with the French Vinci GrandsProjects, has been selected for the construction of the new tunnel and viaducts project in the I-64 Hampton Roads for an amount of 3,000 million euros, which will be the largest infrastructure project in the history of the State of Virginia (USA), as reported this afternoon. The Spanish company presided by Florentino Pérez will lead the consortium in charge of designing and building this megaproject, with a 67% stake in the UTE. It will be one of the largest infrastructure projects in the United States and will strengthen the company's position on the East Coast of the continent.

The stretch of I-64 at Hampton Roads in southeastern Virginia is one of the most congested in the region. The existing infrastructure consists of two submerged tunnels with two lanes in each direction between two artificial islands connected by viaducts with both banks. These tunnels were put into service in 1957 (westbound) and 1975 (eastbound) and have a length of

2.3 km. The traffic in these four lanes exceeds 100,000 vehicles per day. The new project will consist of the design and construction of improvements along approximately 15 km between the towns of Hampton and Norfolk. The project includes a new crossing of the 6.3 km bay with a combination of tunnel and viaducts, substantially parallel to the existing route, with the total reconstruction of the existing viaducts between the artificial islands and both banks. The two new twin tunnels will add four additional lanes of traffic resulting in a total of 8 lanes of traffic and will be built using a state-of-the-art tunnel boring machine, as explained by ACS.

On the land side, the project includes adding a third lane on I-64 in each direction, with a sufficient roadway to accommodate a multi-purpose shoulder that can be used as a traffic lane during peak hours. To reduce congestion and optimize travel times in the corridor, the new project will also include high occupancy toll lanes in each direction.
