Project

Illinois Route 2 Reconstruction

Location

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.
