Ketchikan closes Gorge and Sayles streets through fall 2026 for viaduct replacement

Gorge Street and Sayles Street in Ketchikan are fully closed to vehicles through fall 2026 for viaduct replacement work, forcing motorists to find alternate routes while construction crews operate six days a week in the residential neighborhood.

The Alaska Department of Transportation and Public Facilities is replacing the existing Sayles/Gorge Street viaduct structure west of downtown Ketchikan. The project is part of a broader series of viaduct-related projects in Ketchikan, including maintenance and repair work on Tongass Avenue and Water Street viaducts. The project is scheduled for completion by September 15, 2026. Pedestrian access to residences will be maintained throughout the closure.

Construction crews are working from 7 AM to 5:30 PM, Monday through Saturday. Motorists should expect increased heavy vehicle traffic in the area and use caution near the work zone.

Motorists can check Alaska 511 for current traffic conditions and project updates.
