Abstract:
The construction of the I-205 crossing of the Columbia River between Portland, Ore., and Vancouver, Wash., involved many different types of concrete construction. Among the methods discussed are: the use of one-piece welded steel bell forms for pier base construction, precast and cast-in-place + concrete segmental construction for prestressed spans up to 600 ft (183 m) in length, and modular falsework systems.
