Napaskiak Boardwalk

Project Location: Napaskiak, Alaska

Many rural Alaskan communities utilize boardwalks as the primary means of transportation due to high water levels and poor soil conditions.  In the Village of Napaskiak, which is located in western Alaska along the shores of the Kuskokwim River, over 4 miles of at-grade and elevated boardwalks were constructed to provide safe transportation .  The boardwalks were constructed of wood and steel frame components.  At-grade sections were founded on post-pad systems and elevated sections were founded on helical piles.  The boardwalk's structural design requirements were evaluated based on AASHTO LRFD Guide Specification for the Design of Pedestrian Bridges, Minimum Design Loads for Buildings and other Structures, the International Building Code, the Manual of Steel Construction and the National Design Specification for Wood Construction.
