Terminal 91 Berth 6 and 8 Redevelopment

The project will redevelop berths 6 and 8, and provide 750 feet of moorage to ensure the long-term viability of the Port as the home to the North Pacific Fishing Fleet while improving the marine environment by removing creosote timber pilings.

Project Overview

This project will redevelop Berths 6 and 8 along the northeast side of Pier 90. Improvements include pile replacement, a new wharf structure, a new float system, bulkhead improvements, and office consolidation for operations, fishing and industry customers. The new berths will be equipped with shore power for fishing and industrial vessels.
