Alaska Department of Transportation and Public Facilities, Division of Design and Engineering Services, Point of Contact William Kulash, 2301 Peger Road, MS-2550-07, Fairbanks, Alaska 99709, states the purpose is to improve safety of the Dalton Highway between MP 120 and MP 135 using current design standards. The project area requires frequent major maintenance operations due to design and safety issues such as narrow roadway, lack of shoulders, substandard embankment material, thawing permafrost, substandard horizontal and vertical geometric features, lack of pullouts for chain-up areas, and major drainage issues. In some areas, where it is not pragmatic to meet current design standards, design exceptions and waivers have been approved by the Federal Highway Administration (FHWA). The proposed repairs and upgrades consist of 55.38 acres of permanent impacts from the discharge of approximately 729,075 cubic yards of fill and 16.72 acres of temporary impacts from the discharge of 136,707 cubic yards of fill into waters of the U.S. (WOTUS), including wetlands, consisting of the components as described in Tables 3 and 4. The Alaska Department of Transportation and Public Facilities (DOT&PF) Northern Region is seeking to improve safety of the Dalton Highway between MP 120–135 using current design standards. This Dalton Highway MP 120–135 Reconstruction Project (project) includes structural embankment replacement, realignments, widening, and resurfacing of the15-mile segment. This is the first phase of a multi-phase project along the Dalton Highway between MP 109-144. All work would be performed in accordance with the enclosed plan (sheets 1-39), dated May 11, 2023. The project extends from mileposts (MP) 120 to MP 135 of the Dalton Highway and includes the Bonanza Creek Material Site at MP 124.5 and the Coldfoot Quarry at MP 172.6. The project midpoint is at Latitude 66.698101º N., 150.664202º W. The project endpoints are at Latitude 66.601134º N., 150.718413º W. and Latitude 66.780075º N, Longitude 150.687711º W.
