It is 40.64 miles (65.40 km) long, in two segments broken by a section of OR 36 and runs north–south.

The concurrency continues west for 1.48 miles (2.38 km) as OR 36, at which point OR 200 heads south through Elmira to Veneta.

At Veneta, OR 200 crosses OR 126 and continues south through Crow and Lorane to the Lane-Douglas County line, where it ends.

An old section of the Territorial Highway continues south as a Douglas County road to Anlauf, where it ends at an intersection with OR 99.

It can be traced to at least 1851, and by 1947 was referred to in a judicial opinion as the "Old Territorial Highway".
