Owl Creek, Peoria Road Bridge

Project Description:

Peoria Road is a Rural Major Collector and is a vital route between the Albany/Corvallis and Harrisburg, Junction City and Eugene.  As of 2019, there are 3,066 vehicles a day, with 14% trucks.  The projected Average Daily Traffic is 4,577 for the year 2039.  As the piles and caps continue to decay, the bridge will likely require load restrictions, which will be detrimental to agriculture and industry. The project is located on Peoria Road just north of the intersection with Harvest Drive.

The existing 21-foot single span bridge over Owl Creek is comprised of 12” prestressed concrete slabs on timber foundations.  The north abutment is very tall with an old concrete abutment acting as a backwall to retain approach fill.  The bridge is too short, and the exposed timber piling, caps and lagging show extensive signs of decay, splits and checks.  The decay in the south abutment has progressed to a point where temporary shoring has been added to keep the bridge open to all traffic.

The existing bridge will be replaced with a single-span prestressed concrete bridge founded on steel pile and reinforced concrete abutments and wingwalls. The roadway width will be 33'-4" to support future traffic needs and better accommodate bicycles that use this road as part of the Willamette Valley Scenic Bikeway that goes from Wilsonville to Eugene. The bridge will also include new approach rails and reinforced concrete end panels at each bridge end to minimize bumps that typically form at bridge ends.

During construction, the road will be closed at the bridge site and traffic will be detoured.
