The Arkansas Department of Transportation is soliciting bids for Job 070458, a grade separation project located on Highway 82 in Columbia County, Arkansas. The primary objective is to construct a four-lane median structure, specifically a continuous plate girder unit measuring 856.16 feet, to facilitate a grade separation over the Union Pacific Railroad (UPRR). The comprehensive scope of work includes clearing and grubbing, earthwork, excavation, fill, and the construction of bridge and drainage structures. Additional roadway improvements consist of aggregate base course, asphalt pavement (including cold milling and patching), approach slabs, gutters, concrete ditch paving, guardrails, rumble strips, and pavement markings. The project involves significant coordination with the Union Pacific Railroad, requiring contractors to adhere to specific insurance, construction, and flagging requirements, including right-of-entry agreements and safety platform protocols. Environmental compliance is a critical component, with mandatory adherence to a Storm Water Pollution Prevention Plan (SWPPP) to manage sediment, waste, and water quality. Contractors must comply with USA Corps of Engineers Section 404 permits and Section 7 of the Endangered Species Act. Regular inspections will be conducted every seven days to ensure erosion and sediment controls meet manufacturer specifications and regulatory standards. Project administration is managed through the ARDOT Program Management Division, with the District Engineer David Archer and Resident Engineer Dalton Champagne serving as key points of contact.
