In late January 2025, construction crews successfully installed five massive 295-foot-long steel girders over a single weekend as part of the $660 million, 2.5-mile extension of the Interstate 495 Express Lanes in Northern Virginia. This significant achievement marks a major milestone in the 495 NEXT project, which aims to improve traffic flow and connectivity in the region. The girders, each weighing between 70 and 80 tons, will support a new express lanes ramp at the I-495 interchange with the Dulles Toll Road, enhancing access to Dulles International Airport.
The decision to complete the girder installation in a single weekend was driven by the dense urban environment and the need to minimize disruptions during events such as the presidential inauguration. The project team, including lead contractor Lane Construction Corp. and subcontractor Shirley Contracting Co., coordinated closely with stakeholders for over a year to plan the operation. The 495 NEXT project is being delivered through a public-private partnership between Transurban and the Virginia Department of Transportation.
Infrastructure projects like the I-495 Express Lanes extension can have significant impacts on nearby properties. While improved transportation infrastructure can enhance accessibility and potentially increase property values, construction activities may also bring temporary disruptions, noise, and changes in traffic patterns.
