U.S. Route 28
|Length||462 mi (744 km)|
|West end||US 99 in Eugene|
|East end||US 20 in Ontario|
U.S. Route 28 (US 28) is a defunct designation (since the early 1950s) of an east–west highway that was located completely in the U.S. state of Oregon. It connected US 99 in Eugene with US 20 in Ontario.
In 1937, US 28 was truncated from Florence to Eugene, which then became its western terminus in Eugene. US 28 was replaced with US 26 when US 26 was extended from Wyoming to the Pacific Ocean in 1952. The portion of US 28 from Ontario to Prineville became US 26. That highway then continued in a northwesterly direction to Portland and Astoria. From Prineville to Eugene, US 28 became U.S. Route 126, now known as Oregon Route 126.
At the intersection with Route 126, the old designation of US 28 follows US 26 and picks up the Ochoco Highway No. 41, which also follows OR 126 west to US 97 in Redmond. The Ochoco Highway ends at OR 19 near Dayville, from which US 28 followed the John Day Highway No. 5 through John Day to US 20 in Vale. The remainder of US 28 in Oregon overlapped US 20 on the Central Oregon Highway No. 7 to the Idaho state line.
