HSIP: Central Region Guardrail Inventory and Upgrade

Project Overview

The Alaska Department of Transportation and Public Facilities (DOT&PF), Central Region, under the Highway Safety Improvement Program (HSIP), prepared an inventory of guardrail segments, end terminals, and associated hardware along highspeed (50 mph or greater) routes in Central Region for damage and adherence to current DOT&PF and Federal Highway Administration (FHWA) standards. The inventory results were used to design replacements or upgrades to guardrail segments found to be in non-conformance with current State and Federal standards.

Current Status

Crews inspected approximately one million linear feet of guardrail and 2,200 end terminals in the Central Region during 2020 spring and summer. Findings indicated roughly half of these systems qualify for upgrades. Environmentally sensitive areas, including the location of wetlands and bald eagle nests, were also identified as a part of 2020 field work. In 2021, the project team completed plans and bid-ready engineering construction documents. Construction began in 2023 and is expected to be complete by fall 2024.
