Sauvie Island Bridge Move
Portland, OR
Dix Corporation was awarded a subcontract by Max J Kuney Co. for the load-out, jacking, transport and placement of the Sauvie Island Bridge project located near Portland, Oregon. Dix’s contract included load-out, jacking, moving and placing the 365’ long, 44’ wide, 1680 ton bridge onto new concrete abutments, constructed by Kuney. In order to accomplish this work a jacking and skidding system was designed that allowed the bridge to be moved onto a barge. Because the barge was lower than the pier a system of towers were placed on the deck and once the bridge left the dock it was moved forward on the barge, using a combination of the skid system on shore and hydraulically operated dollies on the barge deck. When this phase was complete the distance between the bottom of the bridge to the deck was about 20’. At this point the barge was moved to the protected end of the pier where four hydraulic jacking towers were constructed and the bridge was raised another 60’. The barge was then moved down river to Sauvie Island where tugs moved the barge into position so the bridge could be jacked down onto the new foundations and grouted. In May of 2008 Dix will reverse the procedure and remove the old bridge from its foundations and move it back up river.
