Lake Creek Bridge, Covered road bridge in Lane County, Oregon, United States.

Lake Creek Bridge, also called Nelson Mountain Bridge, is a 105-foot covered bridge carrying Nelson Mountain Road over Lake Creek near Greenleaf in Lane County, Oregon. Its upper and lower truss chords are each cut from one-piece old-growth timbers, and it has narrow ribbon windows at the eaves and portals shaped as truncated rectangular arches.

Built in 1928, the Lake Creek Bridge carried Nelson Mountain Road over Lake Creek near Greenleaf in Lane County, Oregon. It is listed on the National Register of Historic Places. A 1984 renovation added reinforced concrete abutments and new flooring to raise its load capacity.

This bridge shows how early 20th-century engineers skillfully used wood from local forests to create safe crossings for nearby communities. The construction reflects the craftsmanship and practical knowledge that people relied on during that era.

Access is generally good, though the bridge is relatively narrow and not designed for modern heavy vehicles. Visit during dry conditions, as wet weather can make the wooden surfaces slippery and unsafe.

A major renovation in 1984 added reinforced concrete supports and new flooring while keeping the structure's original appearance intact. This restoration work demonstrates how old wooden bridges can be strengthened for modern use without losing their historical character.
