Illinois Route 2 Reconstruction
Ogle County, IL
William Charles Construction completed the reconstruction of approximately 7 miles of Illinois Route 2 along the Rock River in Northern Illinois. Although the project was scheduled to be completed in two separate sections over a two year period, which would severely impact a major route of travel in this region, our team developed a plan to expedite the work and deliver substantial completion in just one construction season. Aside from the work zone constraints between the river and steep wooded bluffs, one of the larger challenges was to furnish and install nearly 200,000 SF of articulated concrete revetment mat for slope protection that extended to the river bottom up to 15 feet below the water surface. GPS controlled excavators were utilized to maintain grade control and divers with specialized training were employed to assist with this task. The project also included steel beam and pre-cast panel retaining walls at four locations extending up to 24 feet high, rock fill placed in the river to widen the footprint of the highway, storm water management and drainage components, concrete mainline pavement, and concrete shoulders. Major items of work included: 160,000 CY of earth excavation; 27,000 CY rock excavation; 93,000 SY pavement and shoulder removal; 28,000 TN rock fill in the river; 192,000 TN of stone base; 208,000 SY concrete mainline pavement and shoulders; 6,800 LF of pre-cast box culverts & storm drainage; $500,000 miscellaneous concrete; and $5.6 million structural components & retaining walls. Total value of the project: $28 million.
