HSIP: Dalton Delineator Upgrade MP 247-362

Introduction

After confirmed success from the Dalton Delineator test project, we are continuing to update the delineators along the Dalton North of Atigun's Pass. This project will include upgrading the left and right delineators, with the new vertical and horizontal configuration, from Milepost 247 to 362.

Project Area

This project area will include upgrades along the Dalton Highway to the Delineators, on the left and right sides of the road, starting at Milepost 247 moving north. There is a current construction project, Dalton Highway MP 289-305 Rehabilitation, that includes the upgrade of the delineators through this stretch of road. This project will pickup at MP 305 and continue to Milepost 362, where the original test project began. After this project's upgrades, the Dalton Highway will have the new configuration of delineators starting at MP 247 all the way up to Deadhorse at MP 414, a total of 167 miles.

Project Schedule

The project team is currently working on the design and environmental documentation. We expect this project to be constructed summer 2025.

Purpose

The purpose of this project is to increase the conspicuity of the roadside delineators and thus improving the safety of travelers along the Dalton Highway. With the increased visibility of the Type XI reflective sheeting, in combination with the vertical and horizontal configuration, the delineators will help travelers to differentiate between the left and right sides of the roads.
