Alaska Department of Transportation and Public Facilities (DOT&PF), 2301 Peger Road, Fairbanks, Alaska 99709, states the purpose is to resurface the Edgerton Highway from Mile Post (MP) 24 to MP 29 in order to preserve and extend the service life of the highway and to enhance safety. The roadway would be repaved using Hot Mix Asphalt. To achieve this, the current roadway is proposed to be reclaimed using a milling machine or reclaimer. The surface is proposed to be graded and paved to as-built conditions. In addition to resurfacing, the following activities are proposed: Vegetation clearing along the proposed alignment (within the right of way boundary) and in material sites, replace signs, replace guardrails, reconditioning ditches, replace existing culverts, reapplication of pavement markings, and resurface approaches. Two 24 inch culverts would be replaced with 36 inch culverts along the project corridor for cross-drainage along the highway between MP 27 and MP 28. Replacement culverts at these locations would be installed in the same place and at the same depth as existing culverts using half width construction. Following culvert replacement work, discarded culverts and any temporary fill material in wetlands would be removed, then disturbed areas graded and seeded. Approximately 0.1-acre of palustrine scrub-shrub (PSS) wetlands would be temporarily impacted to support the replacement of two cross-drainage culverts. Temporary impacts would result from a 50 foot wide work area that would be driven on by construction equipment. If there is standing water, then perimeter control using best management practices (BMP’s) would be installed. Temporary wetland impact areas would be rehabilitated following construction activities. Materials for this project would be from these existing material sites (MS): MS 850-032-5 (South Liberty Falls Pit), and MS 850-033-5 (North Liberty Falls Pit). The project would utilize approximately 2,000 cubic yards of D-1 and 3,800 cubic yards of paving aggregates. Approximately 3 acres of PSS wetlands would be permanently impacted from removal of material at the North Liberty Falls Pit. All work would be performed in accordance with the enclosed plan (sheets 1-18), dated October 30, 2007, and October 14, 2022. The project site is located on Edgerton Highway (MP 24-29) at Latitude 61.6204º, Longitude -144.5362º; near the City of Chitina, Alaska.
