Will County highway transportation is defined by three major interstates 80, 55 & 57 along with the I-355 Toll Road. Interstate 80, the second longest interstate in the U.S., provides the primary east-west route through the county. The intersection of I-80 and I-55 in the City of Joliet handles a high volume of through traffic in addition to locally generated traffic.
State Highway Improvements
2019 was a banner year for transportation infrastructure funding in Will County. The number one priority high project-the reconstruction of Interstate 80 from Minooka to New Lenox - received $1.2 billion from the state of Illinois through the ReBuild Illinois Capital Plan and the Five Year Multi Year Plan for Illinois Department of Transportation (IDOT).
Through the hard work of Will County legislators and local municipal and County officials, Governor JB Pritzker proclaimed the I-80 reconstruction as the "signature project" of ReBuild Illinois. The I-80 Coalition, a grassroots initiative made up of local and regional leaders in business, labor and government, helped push this project as a priority for the Illinois and national economies.
Other projects scheduled to receive funding from the $21.45 billion IDOT plans to invest in Will County in the next five years include:
