location map

Purpose and Need

Purpose

The Klondike Highway is the primary transportation link between Southeast Alaska and Canada. The purpose of this project is to improve the condition of the highway by implementing the following:

  • Address pavement deficiencies between MP 0.0 and MP 13.1
  • Construct embankment and repair slopes
  • Replace guardrail
  • Improve existing drainage
  • Replace existing signage

Need

The project’s needs are identified as follows:

  • The composite roadway pavement condition for the corridor, based on current FHWA standards, is rated as ‘Poor’ with a recommended treatment of rehabilitation.
  • Numerous unstable slopes and deficient embankments along the corridor result in repeated Maintenance and Operations (M&O) expenditures and impacts to users.
  • Culverts are failing and have reached the end of their service life. Back slope sloughing and erosion at culvert inlets and outlets will also be addressed to promote positive drainage.
  • Guardrail in the project corridor is damaged or is out of compliance with current standards and requires replacement.
  • Signs lack reflectivity and do not meet current standards or are missing.

Project Description

Project activities may include:

  • paving
  • pavement rehabilitation
  • drainage improvements, including culvert improvements
  • bridge improvements
  • adding/replacing guardrail and guardrail end treatments, lighting , snow poles, striping, and signs
  • adding retaining walls

Construction of the first 3-mile segment is anticipated to occur starting in 2024. The entire corridor will be divided into segments with multiple construction projects occurring in the following years.
