I-74/I-155 Interchange

In 2012, the Illinois Department of Transportation – District Four selected Hutchison Engineering, Inc. to provide construction inspection services for the I-74/I-155 Reconstruction project. This project featured the reconstruction and widening of 3.0 miles of I-74 along with a complete reconstruction of the I-74/I-155 interchange near Morton, IL. The project included widening I-74 from 4 lanes to 6 lanes with a concrete median barrier, reconstructing the I-74/I-155 interchanges to improve safety, and reconstruction of 6 structures, highway lighting, and installation of Intelligent Transportation Systems (ITS) elements for traffic monitoring. To maintain traffic flow throughout construction, the project included a complex staging plan with 14 separate stages. The Hutchison Engineering inspection team worked very closely with the contractors to make minor adjustments to operations to throughout construction to reduce staging changes while providing safe travel through the construction zone. Construction of this $86 million project began in 2013 and was completed in 2016.
