Highway No. 227 (see Oregon highways and routes), an east-west freeway through the Eugene-Springfield metropolitan area. OR 126 is routed along this freeway for its entire length. West of the I-5 interchange, the freeway is also designated as I-105, a spur of I-5. At this point, I-105 and OR 126 enter Eugene. After two exits and a Willamette River crossing, I-105 reaches its western terminus at OR 99 (West Sixth Avenue) between Washington and Jefferson streets. The bridge and viaduct carrying the last of I-105 are sometimes known as the Washington-Jefferson Street Bridge. In December 2011 the section of highway from the Washington-Jefferson Street Bridge to Springfield was renamed Officer Chris Kilcullen Memorial Highway to commemorate the fallen Eugene Police Department officer who was fatally wounded while conducting a traffic stop on the highway in April 2011. Springfield to Prineville OR 126 travels east on the McKenzie River Scenic Byway, flanking the McKenzie River for most of its length from Springfield into the Cascade Range. It turns north at Belknap Springs and follows the Clear Lake-Belknap Springs Highway, passing the eponymous Clear Lake. The highway merges with US 20 near Crescent Mountain and begins a concurrency that continues through Sanitam Junction (the terminus of OR 22) and Sisters.

In 1937, the same year a new US 99 alignment between Eugene and Junction City opened, US 28 was truncated and its western terminus moved to Glenwood (between Eugene and Springfield). On February 1, 1952, US 28 was eliminated from the United States Numbered Highway System.
