The contractor must provide notification of closure dates at least 21 days in advance to state agencies and 14 days to local municipalities and emergency services. Work is subject to supplemental specifications and special provisions addressing concrete pavement, asphalt, bridge deck construction with slipform parapet options, fiber-reinforced polymer wraps, preformed pavement joint seals, and environmental compliance for soil contamination management at ISGS Site 4602-2. The project is federally funded under the National Highway Performance Program and requires full compliance with Federal Highway Administration standards, MUTCD traffic control guidelines, and Illinois Department of Transportation specifications adopted January 1, 2026.
