Inter-Continental Peace Bridge, Inc., was organized in 1968. The purpose and vision of this organization is to join the continents of the world by connecting the shores of Alaska and Siberia. To meet functional, aesthetic, safety, and economic requirements, this unprecedented project will continue to need extensive engineering study and evaluation. However, there are no insurmountable technological problems concerning the building of this bridge. Design for strength, durability, and wind and earthquake resistance can be attained using available knowledge and experience. The one major problem is resistance of bridge piers against ice floes. Ice floes up to 6 feet thick are in constant motion during certain seasons. As a result, horizontal forces in the order of 5,000 tons or more can develop on a pier. To overcome this problem, the prefabrication and construction of this bridge will be almost entirely accomplished by using precast and prestressed concrete. The bridge would consist of 220 spans, 1,200 feet in length, most of which will need a vertical clearance of only 80 feet.


The substructure will be composed of 220 precast, prestressed gravity piers, each made with a shallow base raft supporting a double-curved cylindrical tower.


A single stay cable scheme has been determined to be the most economical because the large box section can span 400 feet between the supports with a minimum number of cables. This reduces maintenance costs due to severe weather conditions at the bridge site.
