We reconstructed eight miles of the existing 4-lane rural Interstate I-90 expressway and transformed it into a 6-lane modern interstate highway with a permanent concrete median barrier wall and roadway lighting. This project was completed within two construction seasons and included completely removing the existing pavement and road shoulders, earth excavation and grading, plus the construction of three new lanes of concrete pavement in each direction on a 3 in. warm mix asphalt sub-base. The new concrete pavement was built as a two-lift concrete pavement, using salvaged asphalt pavement in the bottom layer of the concrete pavement. All of the existing asphalt and concrete pavement was salvaged and used for the new 6-lane interstate highway.
The Illinois Tollway awarded Curran Contracting “Roadway Contractor of the Year” for this project.
