About this file
This is a presolicitation document for a federal construction project at Yellowstone National Park in Wyoming.
The project, WY NP YELL 10(24), involves 4R roadway reconstruction of the Grand Loop Road from Norris to Golden Gate, Phase 3, spanning 0.7 miles plus a parking lot located 0.4 miles southwest of Mammoth, WY. The work scope encompasses excavation, blasting, rock scaling, embankment and drainage improvements, parking area improvements, roadside improvements, retaining wall construction, stone masonry, utility and waterline relocation, boardwalk construction, obliteration, base aggregate installation, asphalt paving, concrete curb and gutter, striping, and signage. The estimated price range is $45,000,000 to $55,000,000, with a tentative solicitation date of Winter 2026/2027 and a tentative fixed completion date of Fall 2028. The document provides a detailed breakdown of work quantities organized by division, including project requirements (survey, quality control, erosion control), earthwork (clearing, grubbing, excavation, rock blasting), slope reinforcement and retaining walls, aggregate and base courses, asphalt pavements, incidental construction (culverts, drains, curb and gutter, water systems, sidewalks, stone masonry, traffic control), and landscaping elements. Three schedule options (Schedule A, Schedule B, and Option Z) are presented with varying quantities for specific line items, allowing for flexibility in project scope or phasing.
