The Interstate 90 (I-90) widening project in the state of Illinois, US, is a road reconstruction and widening project of a section of a highway. The section of road is the Newburg Road to Rockton Road located to the south of Wisconsin border. The 14.3 mile-long, single-lane section is being widened to three lanes in both directions to provide traffic-clogging relief for travellers. The project is estimated to cost $180.2m. In 2004 Illinois Tollway approved a comprehensive development plan known as the Congestion-Relief Program for the purpose of modernising roadways, with a budget of $6.3bn during the period from 2005 to 2016. The Jane Addams Memorial Tollway is a 79-mile segment of the I-90. The tollway begins at the intersection of the Kennedy Expressway (I-90) and the I-190, and runs west to Rockford and north to just below the Wisconsin state line. Ongoing projects on this tollway are the I-90 mainline Reconstruct & Widen Project and the Cherry Valley Interchange Reconstruction Project, which are both part of the Congestion-Relief Program. The Cherry Valley Interchange Reconstruction Project includes reconstruction and reconfiguration of the Cherry Valley Interchange. It connects the I-90 to the I-39 in Rockford. An amount of $89m is allocated to the project from the Congestion-Relief Program. The project is undertaken by the Illinois State Toll Highway Authority (Illinois Tollway), the state-owned entity run by the Governor of the State of Illinois and the Illinois Department of Transportation's head, along with nine other board directors. The collection of tolls, maintenance of tollways, construction of new tollway roads and restructuring of existing tollway roads are the principal duties of the agency. The general contractor for the project is Rockford Blacktop Construction and the subcontractor is Rock Road Companies. Construction The I-90 reconstruction started in 2007 and was scheduled for completion within two years. The project is being executed as scheduled and the completion date is expected to be November 2009. The road from Newburg Road to East State Street will be completed by the end of November 2009, whereas the reconstructed and widened road from East State Street to Rockton Road has already been completed and opened. In 2007, the advance construction works from Newburg Road to Rockton Road were completed. Restructuring and widening works in the eastbound lanes from the South Beloit Toll Plaza to State Street were completed in 2008. During the same year, the restructuring and widening works were also completed between the South Beloit Toll Plaza and Rockton Road. Construction works in the westbound lanes from Newburg Road to the South Beloit Toll Plaza were completed in 2009. I-90 bridges There are eight crossroad bridges located in the route of the project: Swanson Road Bridge, Elevator Road Bridge, Belvidere Road Bridge, Newburg Road Bridge, Harlem Road Bridge, Spring Creek Road Bridge, Rote Road Bridge and Rock Cut State Park Bridge. There are eastbound and westbound mainline bridges along the roadway, all of which have been restructured and reconfigured as part of the road-widening project. Traffic management system During the construction stage, traffic on the tollway was shifted and ran on one side of the road. Two lanes for vehicles in both directions were provided during the construction. Lane closures took place mostly during the night and, when required, occasional closures were done during the day, but avoiding peak times. All the entrance and exit ramps were kept open during the construction process. A 45mph speed limit was imposed at the construction zones throughout the construction period, with a hefty fine for anyone who hits a construction worker.
