On June 9, 2010. Governor Pat Quinn was joined by Indiana Governor Mitch Daniels to sign legislation that will bring the two states together to build the Illiana Expressway, connecting I-55 from south of Joliet to I-65 near Lowell, Ind. The Illiana Expressway will connect drivers on I-55 in Western Will County to I-65 in Lake County, Ind. In addition, the Illiana Expressway will serve as an alternate route for motorists traveling the I-90/94 corridor. The new Illiana Expressway will also provide much needed access to Will County's burgeoning freight and logistics centers and create more jobs in Will County to serve its fast-growing residential population.

The new east-west connection between northeast Illinois and northwest Indiana will result in decreased travel time, enhanced safety, and increased reliability for travelers in Illinois and Indiana. The Illiana Expressway will allow for more efficient movement of goods between transportation modes, while attracting new logistics and manufacturing companies looking to gain greater access to the marketplace.
