Granite Selected for I-290 Drainage Improvements Under IDOT’s First CM/GC Contract

WATSONVILLE, Calif.--(BUSINESS WIRE)--Granite (NYSE:GVA) announced its selection by the Illinois Department of Transportation (IDOT) for a Construction Manager/General Contractor (CM/GC) contract for the I-290 Drainage Improvements Project in Chicago, Illinois. This federally funded initiative will be included in Granite’s third quarter CAP.

The project includes the installation of 3.3 miles of new trunk sewer, with diameters reaching up to 90 inches, the construction of new detention systems, and the reconstruction of one bridge and multiple retaining walls. These upgrades are designed to enhance stormwater management and reduce flooding risks along the Eisenhower Expressway corridor.

“We’re honored to be selected for IDOT’s first CM/GC contract. This is a tremendous opportunity for our team,” said Granite Project Executive, Brad Jacobson. “As the initial phase of a proposed $6 billion I-290 corridor-wide improvement program, this project represents a major investment in the future of Illinois transportation. We’re proud to partner with the IDOT Innovative Project Delivery team to deliver innovative infrastructure solutions that benefit communities throughout the region.”

The CM/GC delivery method enables early contractor involvement, enhancing coordination and constructability throughout the design and construction phases. Granite’s Midwest Region and Tunnel Division are teaming up for this project.

Preconstruction activities are expected to begin in November 2025. The total anticipated construction value is estimated at $350 million and is expected to begin in Q1 2027 and be completed in Q4 2029.
