The beginning of the project is located at Dalton Highway Mile Post (MP) 18 at approximately Latitude 65.601411° N., Longitude 149.066394° W.; the end of the project is located at Dalton Highway MP 37 at approximately Latitude 65.759015° N., Longitude 149.375873° W. The project site can be reached by taking the Elliot Highway north out of Fairbanks, Alaska for approximately 82 miles to the start of the Dalton Highway and continuing along the Dalton Highway for approximately 18 miles, approximately 100 miles north of Fairbanks, Alaska.
Purpose: The applicant’s stated purpose is to reconstruct the Dalton Highway between MP 18 and MP 37 to improve highway safety and performance, bring the roadway up to current design standards, reduce annual maintenance costs, and improve drainage and fish passage where applicable. For the replacement of Hess Creek Bridge, the applicant’s stated purpose is to widen the bridge to accommodate passing commercial trucks operating at speeds of approximately 50 miles per hour.
Project Description: The proposed repairs and upgrades consist of 83.38 acres of permanent impacts from the discharge of approximately 672,201 cubic yards of fill and 23.84 acres of temporary impacts from the discharge of 5,418 cubic yards of fill into waters of the U.S., including wetlands, consisting of the following components as described in Tables 2, 3, and 4.
