 Alternative C3 (a) is a bridge that would span Tongass
Narrows approximately 500 meters (1,600 feet) north of the airport
terminal. The main span of the bridge would have a vertical
clearance of 61 meters (200 feet) and a horizontal clearance
of approximately 198 meters (650 feet). The vertical and
horizontal clearances of the main span would allow for one-way
passage of cruise ships and two-way passage for most other ships,
including Alaska State ferries, under the bridge. The bridge
would connect to Signal Road on Revillagigedo Island and would
traverse the hillside southward, gaining elevation and turning
southwestward to cross Tongass Avenue and Tongass Narrows, and
then turning southward to parallel the airport runway and touch
down south of the terminal. An airport return loop road
would connect the terminal to the bridge. The road would
continue around the south end of the airport runway and then
arc northward, extending parallel to and west of the airport
runway approximately 3.5 kilometers (2.2 miles) to the north
end of the Airport Reserve property. The road at the south
end of the runway would be constructed at a grade low enough
to allow for future runway expansion plans; i.e., the runway
would be expanded as an overpass of the road. The EIS is assessing the no-action alternative and nine build alternatives:
