The $16.6 million project connects 3rd Avenue between Washington Street and Schoenbar Road in Bear Valley. It is approximately one mile long, located directly above Ketchikan's 2nd Avenue residential area in steep, forested terrain. The project includes the innovative use of roller compacted concrete to construct the difficult central segment of the project. The RCC embankment is approximately 90 feet high at its maximum, and supports approximately 1,000 feet of the new roadway. RCC technology has a long history in dam construction, but fairly limited use in highway construction. It's use on the Ketchikan project is a first for Alaska. When open, the 3rd Avenue "bypass" will provide a long-sought second route for traffic from Ketchikan's west end to the downtown area, via Bear Valley.
