| ACS wins the largest infraestructure project in the history of Virginia (USA)  ACS Group, through Dragados USA and Flatiron (Hochtief), in Joint Venture with Vinci Grands projects, has been selected as the best value proposal based on bid price and technical score for the 3.3 billion I-64 Hampton Roads Bridge-Tunnel project in Virginia, VDOT's Largest Construction project in History.Bringing world-class capabilities in tunneling, bridge and highway construction, ACS will lead the consortium to design and build this mega project, with 67 % share in the Joint Venture. This project, one of the largest construction projects in the United States, will further reinforce the footprint and strength of the company in the Eastern United States. The I-64 Hampton Roads Bridge-Tunnel in southeastern Virginia has long been one of the region's most congested corridors. The existing 3.5-mile facility consists of two 2-lane immersed-tube tunnels on artificial islands, with trestle bridges to shore. These tunnels opened in 1957 (current westbound lanes) and 1976 (eastbound lanes) and are approximately 7,500 feet long. Traffic on these four lanes exceeds 100,000 vehicles per day during peak summer traffic. The project will consist of the design and construction of improvements along approximately nine (9) miles of the I-64 corridor between Settlers Landing Road in Hampton and I-564 in Norfolk. The scope includes a new bridge-tunnel crossing, approximately 3.5 miles long and generally parallel to the existing Hampton Roads Bridge-Tunnel, and replacement of the existing marine approach bridges between the Hampton Roads Bridge-Tunnel islands and the shorelines. The new twin-tunnels, which will be constructed as bored tunnels using a state-of-the-art TBM, will add four new lanes of traffic resulting in a total of eight lanes of capacity across the water. On land, the project includes the addition of a third lane to I-64 in each direction with a roadway section sufficient to accommodate a part-time median shoulder lane. To optimize congestion management and increase travel time reliability along the I-64 corridor, the new capacity created by the project will include high-occupancy toll lanes in each direction. write your comments about the article :: © 2019 Construction News :: home page |
