I-84 Sandy River and Jordan Rd. Bridges
Start Date: Summer 2010
End Date: November 2014
This project will replace two structurally deficient bridges on I-84 located over the Sandy River near Troutdale, Oregon at the gateway to the Columbia River Gorge National Scenic Area. Work began in the early summer of 2010, and will continue through the fall of 2014. Other major work activities include a widening of the Eastbound and Westbound Jordan Road bridges, improved bicycle and pedestrian access, and the construction of a temporary detour alignment. The new bridges will be more environmentally friendly, conform to current safety standards and meet aesthetic requirements of national scenic areas. This project required an innovative Hamilton-designed "top down" process for setting steel girders due to site constraints that made work bridges infeasible.
