[edit] Route description

OR 18B begins (at its western terminus) at a junction with Oregon Route 18 and Oregon Route 22, at Valley Junction near Willimina. From there it travels eastward just north of the South Yamhill River, with the river occasionally flooding and closing the road.^[2] It passes through the community of Shipley, Oregon, before entering Sheridan. OR 18B then reconnects to OR 18 at the eastern edge of Sheridan.

The business loop was the former main route and highway until 1957, when the current Oregon Route 18 was built as a bypass. Route 18 Business is 8.60 miles long.^[3] The only traffic light on the road is in Sheridan at the intersection of 18B and Bridge Street where Sheridan Bridge crosses the South Yamhill River. In Sheridan the highway is Main Street. It is classified as a Rural Major Connector highway.^[3]

Business 18 averages approximately 5,900 vehicles per day at its eastern terminus and 6,000 near the western terminus in Willimina.^[4] Traffic averages around 5,400 vehicles per day between those two points.^[4]
