Office Bridge, also known as the Westfir Covered Bridge, spans the North Fork Middle Fork Willamette River in Westfir, Oregon, linking the former mill area to the company offices across the river. Built in 1944 after a 1941 bridge was washed away, it carried logging and lumber trucks for the Westfir Lumber Company. At 180 feet, it is Oregon’s longest covered bridge, one of only two in the state with triple Howe trusses, and the only covered bridge west of the Mississippi River with a separate pedestrian walkway. After the mill era ended, the bridge was stabilized, restored, and became part of Westfir’s civic and recreational landscape.
