Project End Result

The Alaska Department of Transportation, in cooperation with Brechan Construction, LLC., is working to repair roadside erosion threatening the safety and stability of the Chiniak Highway at the following ten sites between MP 19 and 42.

Site 1 – Small Creek Abutment Protection / Sheet Pile

Sites 2 & 3 – Realignment / Blasting (Black Creek Canyon and Uphill Rock Face)

Site 4A – Olds River Abutment / Highway Protection

Site 4B – Kalsin River Sediment Trap & Abutment / Highway Protection

Site 5 – Box Culvert Installation

Site 6 – Roadway Realignment / Guardrail

Site 7 – Twin Creek Abutment Protection / Roadway Work

Site 8 – American River Abutment / Highway Protection

Site 9 – Bluff Erosion & Soldier Pile Walls

The two erosion issues endangering the stability of the Chiniak Highway bridges and road embankment are: 1) erosion occurring along coastal bluffs with have steepened causing mass sliding and slumping adjacent to the highway, and 2) erosion occurring at bridges and culverts from flood events and river activity. This project will address these issues by installing abutment and bank protection at several bridges along the route, adding new culverts and erosion protection, reestablishing ditches, installing retaining walls and realigning the highway where feasible and necessary. Project work is expected to be complete in September 2020.
