The I-405/I-105 interchange is one of the most critical arteries in Southern California, handling over 250,000 vehicles per day. Aldridge served as the prime contractor for the Caltrans 405/105 Freeway Tunnel Lighting Upgrade, a project focused on replacing aging infrastructure with modern LED technology and intelligent control systems. The mission was to enhance driver safety and reduce long-term maintenance demands while ensuring minimal disruption to one of the nation's busiest corridors

On Chicago’s South Side, Aldridge supported the replacement of two aging railroad bridges located at 73rd Street and Cottage Grove Avenue. These critical structures are vital to regional transit, carrying more than 70 freight and commuter trains daily.

Aldridge is contributing to the critical buildout of the I-490 Tollway, providing the essential Intelligent Transportation Systems (ITS) and power infrastructure that will support the new western gateway to O’Hare International Airport.

The Opitz Boulevard Access project is a design-build effort improving connectivity to and from the I-95 Express Lanes in Prince William County, Virginia. The project included relocating the southbound slip ramp into the express lanes and constructing a new access point from Opitz Boulevard, enhancing regional access to hospitals, shopping centers, and other key destinations.
