Wilsonville Hayesville Interchange
Start Date: May 2006
End Date: June 2008
This design/build project involved replacement of an existing bridge with twin structures on I-5 south of the Willamette River near Wilsonville, construction of new retaining walls, and 22 miles of repaving on I-5 between Wilsonville and Salem—both northbound and southbound lanes.
“The creativeness and acceleration of work by the design-builder (Hamilton) significantly lessened the impact on traffic flow and improved safety on I-5, the West Coast’s major trade corridor and one of the top freight routes in the nation.”
