The bridge is a replacement for a 1941 bridge which washed away. It was built in 1944 by the Westfir Lumber Company to carry logging trucks and lumber trucks to the company's lumber mill and mill pond. The company headquarters and offices were located across the river beside National Forest Development Road 19, in what is now a bed and breakfast. The bed and breakfast retains the company's walk-in safe.
The company-owned town of Westfir, the mill, and the bridge were sold to an investment firm in 1977. The lumber mill burned to the ground in the early 1980s. In 1992 the bridge ownership changed to Lane County due to property tax foreclosure. Extensive structural work in 1993 stabilized the bridge. In 2002, the roof was replaced.
Formerly, the bridge was closed to public access. In about 2003, a small park was established on the north side of the bridge. The park also serves as a trailhead to North Fork Trail #3666, which follows the Wild and Scenic section of the North Fork river. The Wild and Scenic designation ends a few hundred feet upriver from the bridge.

This covered bridge is beautiful, and feels a bit off the beaten path, in a neighborhood crossing over towards a more forested area. Train goes over the river nearby, and that was pretty cool to watch too.
I was surprised to find that this bridge had only been built in 1945. The construction was quite interesting seeing how they made it strong enough to support 20 tons.
