Scope Of Work
In a joint venture with Sundt Construction, Inc., Slayden was contracted to replace the original, deteriorating structure with a wider, pedestrian-friendly bridge that could accommodate the ’s growing traffic volume. The project team utilized a bold approach to construct the new bridge without shutting down traffic flow. The approach involved lifting the old bridge deck and truss with hydraulic jacks and moving it to one side, then placing it on a set of temporary piers and connecting it to temporary approach spans so that traffic could continue to use it while the new bridge was constructed. The 1,100-foot-long steel bridge truss was moved in a single 12-hour operation and became one of the longest bridge sections ever to be moved.
The new Sellwood Bridge was designed to the latest seismic standards and construction engineering which address both 500 and 1,000-year recurrence period earthquakes.
Arched form fits the natural setting and is appropriate to neighborhood scale.
Sustainable – components are made of recycled steel.
Increased safety and traffic performance.
