Illinois Tollway Elgin-O’Hare Expressway

M Squared Engineering, LLC (M²) was a part of the construction management team overseeing the construction of the new tollway (IL-390), the IL-83 interchange, and frontage roads. Utility relocation work for the Elgin O’Hare Tollway, from Lively Blvd. to Thomas Dr., began in the Summer of 2015 and concluded in the Spring of 2016. This work was executed by multiple separate construction contracts, including the construction of the new Thorndale Ave., East and West frontage roads, which began in the Spring of 2016, along with water main and storm sewer work. The pavement construction was completed in early summer. In August 2016, traffic was shifted from old Thorndale Ave. to the new frontage roads.  M² involvement in this construction project concluded in November 2017 as the project construction contract was wrapping up.
