The Illinois Department of Transportation (IDOT) has shortlisted four development teams to construct a 35-mile portion of “Illiana” Expressway, a planned 47-mile corridor linking major Illinois and Indiana highways. Earlier this month, the four teams responded to a request for qualifications to construct portions of the corridor extending through Indiana.

As planned, the $1.5-billion Illiana would connect I-65 in northwest Indiana to I-55 in northeast Illinois, about 58-miles south of Chicago, thereby relieving truck congestion on I-80, an east-west corridor in closer proximity to the city.

State transportation officials expect Illiana to generate $2.4 billion to $3.8 billion over the life of the   the development contract they've proposed, with developers recouping their investments from tolls the highway accrues through 2052.

The four teams selected by IDOT include:

Illiana West Mobility Partners

Equity Members: Cintra Infraestructuras, S.A.; Lead Contractor: Ferrovial Agroman US Corp.; White Construction Inc.

Illinois Corridor Connection Group
