In the 19th century, a school/geographical district in northeastern Greenwood Township was known as the Green Creek District, after Green Creek, which flowed through it. A covered bridge known as the Patterson Covered Bridge was built over the creek in 1875 by Frank Derr for $804 and was named for a nearby sawmill. A concrete tee beam bridge carrying T-682 over Green Creek was built west of Benton in 1923 and is long. Another bridge of the same type, but carrying Green Creek Road over the creek, was built in 1934 south of Waller and is long. A third concrete tee beam bridge, this one carrying T-455, was constructed across Green Creek in 1936 north-northwest of Rohrsburg and is long. In 1961, a two-span prestressed box beam or girders bridge carrying State Route 4020 was built across the creek north of Orangeville and is long. A two-span steel culvert bridge carrying T-761 over the creek west of Benton was built in 1986 and is long.

Biology The drainage basin of Green Creek is designated as a Trout Stocked Fishery and a Migratory Fishery. Wild trout naturally reproduce in the creek from near its headwaters downstream to its mouth, a distance of . As of the late 1990s, brown trout have been observed in the creek. A site known as the Green Creek Floodplain is listed as a "locally significant site" on the Columbia County Natural Areas Inventory. The site consists of a section of the floodplain of Green Creek forested with hemlock in Jackson Township. Other environmentally sensitive natural features may also exist along the creek in Greenwood Township. Green
