PROJECT BURNT RIVER BRIDGE REPLACEMENT PROJECT Connecting precast concrete deck panels with ultra-high-performance concrete by George Bornstedt and Craig Shike, Oregon Department of Transportation PROFILE Burnt River Bridge/Huntington, Oregon Bridge Design Engineer: Oregon DOT, La Grande, Ore. Construction Engineer: McGee Engineering, Corvallis, Ore. Prime Contractor: Hamilton Construction Co. (Oregon), Springfield, Ore. Precaster: Knife River, Harrisburg, Ore. - a PCI-certified producer UHPC Supplier: Lafarge North America Inc. Calgary, Alberta, Canada As part of an ongoing effort to develop methods and materials that increase concrete bridge deck durability, the Oregon Department of Transportation (ODOT) recently constructed the U.S. 30 Burnt River Bridge replacement project located near Huntington in rural eastern Oregon. This Federal Highway Administration (FHWA) Highways for LIFE (HfL) project demonstrated precast, prestressed high-performance concrete (HPC) deck panels composite with precast, prestressed concrete bulb-tee girders and ultra-high-performance concrete (UHPC) connections in a 160-ft-long, single-span bridge. The Burnt River Bridge consists of four 90-in.-deep precast, prestressed concrete bulb-tee girders supporting fifteen 8½-in.-deep, precast, prestressed HPC deck panels that are 9.5 ft wide and 30.8 ft long. The bridge is located on a 15-degree skew and has a 28-ft-wide clear roadway. The bridge spans the Burnt River and a Union Pacific railroad mainline. (continued next page)
