Oregon Route 58: Barnard Bridge
Overview
The Barnard Bridge is located on OR 58 (Willamette Hwy.) at milepost 33.24.  The bridge crosses the Middle Fork, Willamette River approximately one mile west of Oakridge.
 
The Barnard Bridge was built in 1955.  The 593-feet long bridge is constructed with concrete girder spans on the east and west ends and steel girder spans in the middle. 
 
In 2000 a contractor replaced the deck on the steel girder spans and added seismic retrofits, a deck drainage system, and new traffic rail. 
 
The bridge is located on an important freight route where many of the 6,300 Average Daily Trips made by vehicles crossing the bridge are commercial freight haulers.

Project Need
In 2003, ODOT conducted a statewide study of bridge conditions.  During the inspection of the Barnard Bridge, vertical and diagonal cracks were found in the concrete girders supporting the west span. 
                    
In addition, given reinforcement bar standards of the 1950’s and the increased vehicle weight of modern trucks, it was determined that the west concrete span needed repairs and strengthening. 
 
Without strengthening, weight restrictions would have to be imposed on the bridge which would result in redirecting freight haulers.  Such out of direction travel would create a significant economic impact to the freight haulers as well as local economies of the OR 58 corridor.

Project Information
The project will pressure inject the cracks in the concrete girders with epoxy.  The girders will also be strengthened by drilling down through the deck and inserting 204 stainless steel rods known as internal shear anchors.
 
Conway Construction of Ridgefield, Washington was awarded the $125,000 contract.
 
Construction will take approximately two months to complete and is expected to begin by mid-April.
 
During construction, motorists should expect  a single lane of travel across the bridge.  Traffic will be controlled by either flaggers or a single lane traffic signal.  Motorists should plan on 10-20 minute delays at the construction site.
