About this file
This document is a detailed project specification for the Ghiglione Bridge Replacement project in Denali National Park, Alaska. The project involves constructing a new 4-span, 180-foot long steel girder bridge with a cast-in-place concrete deck, located 125 miles southwest of Fairbanks. The work includes structure construction, grading, drainage, base, and erosion control, with a project length of 0.201 miles. The bridge will be founded on steel pipe piles for abutments and piers, and the existing steel girder bridge will be demolished upon completion of the new structure.
The estimated price range is $10 million to $20 million, with a tentative solicitation date in Winter 2025/2026 and a fixed completion date in Summer 2027. The project scope encompasses multiple divisions of work, including mobilization, construction surveys, quality control, earthwork, slope reinforcement, aggregate base courses, bridge construction, and incidental construction. Key quantities include 1,400 cubic yards of roadway excavation, 230 cubic yards of structural concrete, 64,000 pounds of reinforcing steel, 137,000 pounds of steel structures, and temporary traffic control measures including 850 hours of flagging.
