T.Y. Lin International (TYLI) is part of a joint venture selected by the Illinois State Toll Highway Authority (ISTHA) to perform Overall Corridor Construction Management (CCM) for the New Elgin-O’Hare Western Access Project (EOWA). The project includes a 10-mile corridor along the former Elgin O’Hare Expressway and a new six-mile corridor for the new O’Hare Western Access.
Featuring a demanding schedule with multiple concurrent activities, the $3.4 billion EOWA project incorporates over 17 miles of new roads, with 15 new or reconfigured interchanges, ramps, and frontage roads, pavement rehabilitation, the installation of a new, all-electronic tolling system, drainage, and lighting rehabilitation.
TYLI is also providing direct construction inspection services for a $440 million directional interchange between IL-390 and I-290. New construction includes three highway crossings over I-290, two approximately 2,100-foot-long tri-level flyover ramps spanning both I-290 and IL-390, and full access ramps for other traffic movements.
- CCM is being provided for over 15 separate construction contracts, each with its own construction management engineering firm.
- TYLI is overseeing project scheduling for the entire corridor, close to 20 projects to date, many of which are concurrent.
- Direct construction inspection services apply to three separate construction contracts, with work occurring under active traffic conditions and while maintaining traffic flow.
- The EOWA project is a part of the 15-year, $12 billion capital program “Move Illinois: The Illinois Tollway Driving the Future” to improve mobility and reduce congestion in northeastern Illinois.
TYLI will also provide CCM for the construction of new expressway-level pavement from I-290 east to the limits at O’Hare International Airport. This project entails 10 additional construction contracts. Scope of work will include building demolition, earth excavation and embankment, new pavement and bridge construction, new frontage roads, storm sewer installation, barrier wall construction, new electronic toll collection facilities, pavement striping, and landscaping. All construction will be done while maintaining traffic on an existing parallel arterial roadway and vehicular access to adjacent industrial parks.
